Sustainability-In-Tech : New Synthetic Graphite Boost EV Battery Lifespan by 30%

Posted on by Paul Stradling

ExxonMobil has unveiled a new form of synthetic graphite designed to extend electric vehicle battery life by up to 30 per cent, in a move that could reshape the EV materials supply chain.

A Major Energy Player With a New Direction

ExxonMobil is best known as one of the world’s largest oil and gas companies, with operations spanning upstream exploration, refining, petrochemicals and energy logistics. However, in recent years, the company has increasingly turned its attention to low-carbon technologies, focusing on areas where it believes it holds a competitive advantage, such as carbon capture, hydrogen, and chemical-based solutions.

While it has often avoided wind and solar projects, citing a lack of in-house capability, ExxonMobil has consistently invested in R&D in the materials space. This latest development, presented by CEO Darren Woods at the University of Texas at Austin’s Energy Symposium, represents a significant step into the EV battery supply chain.

What Is This New Graphite, and Why Does It Matter?

The material is a newly engineered synthetic form of graphite, used in the anode of lithium-ion batteries, that the company claims can extend battery lifespan, improve charging speeds, and increase vehicle range.

“The carbon molecule structures we’ve developed show real promise for faster charging and longer-lasting batteries,” said Woods during the announcement. “This is a revolutionary step change in battery performance.”

Synthetic graphite is already a critical ingredient in EV batteries, accounting for more than 90 per cent of commercial anode material. However, existing production methods are energy-intensive, supply chains are stretched, and natural graphite sourcing is geographically constrained, with over 60 per cent of global supply currently coming from China.

ExxonMobil says its new form of graphite is designed for consistency and high performance, and can be manufactured using carbon-rich feedstocks derived from existing refining processes. This means the company can use its current infrastructure to produce the material at scale, reducing reliance on mining operations and imported feedstocks.

From Oil Barrels to Battery Materials

The move into battery materials may seem like a departure from ExxonMobil’s traditional focus, but the company actually has quite a long-standing history in the battery space. For example, it co-invented the lithium-ion battery in the 1970s and developed the plastic separator films used in early rechargeable versions.

Now, with the acquisition of Superior Graphite’s US production assets and technology, ExxonMobil is laying the groundwork for a large-scale synthetic graphite business. According to the company’s blog, the acquisition will allow it to build a “robust, American-based supply chain” for synthetic graphite.

“We’re expanding into the advanced synthetic graphite business, and we’re doing it with a name that’s been in the game for over a century,” said the company in a September statement.

Who Could Use This Graphite, and Why Now?

The synthetic graphite is being trialled by multiple unnamed EV manufacturers, although details remain under wraps at present. Industry analysts say it could be especially valuable for high-performance EVs, commercial electric fleets, and energy storage systems (BESS) that require longer cycle lives and more stable charging patterns.

By 2030, demand for battery-grade graphite is projected to exceed 4 million metric tonnes annually (Benchmark Mineral Intelligence). With growing concerns about China’s dominance in graphite processing, Western governments and manufacturers are actively seeking alternative, scalable sources.

For EV makers, better anode materials could reduce the cost per kilowatt-hour of batteries, improve durability, and reduce consumer anxiety around battery degradation.

For consumers, the promise of longer-lasting, faster-charging batteries could mean fewer replacements, longer warranties, and better range per charge, which are all critical factors in encouraging wider EV adoption.

The Implications for ExxonMobil and Its Competitors

Although ExxonMobil has stated it does not intend to become a battery maker, the strategic move into anode materials positions it as a key supplier to one of the fastest-growing industries in the world. The company has said it expects to start commercial production of the graphite by 2029.

This puts ExxonMobil in direct competition with a range of players including Chinese graphite suppliers, Korean battery component firms, and materials companies like SGL Carbon and Syrah Resources. While some rivals focus on natural graphite mined in Africa or South America, ExxonMobil’s emphasis on synthetic production could appeal to buyers looking for stable, traceable, and lower-emissions supply chains.

It could also provide the company with a new source of revenue as demand for petrol and diesel continues to decline in line with electrification targets across Europe, the UK, and North America.

“This isn’t a step in; it’s a full-scale launch with power and purpose,” the company said. “When our product enters the market, we expect it will deliver faster charging and longer life than existing graphite materials today.”

Sustainability Claims Under Scrutiny

ExxonMobil argues that synthetic graphite offers significant sustainability benefits compared to traditional mining. For example, its internal estimates suggest the process could be less energy-intensive, more land-efficient, and have higher throughput than natural alternatives.

However, the environmental impact of producing synthetic graphite at scale remains a subject of debate. Critics point to the use of fossil-based feedstocks, the carbon footprint of high-temperature furnaces, and the lack of independent life cycle analysis to support the company’s claims.

Some experts have welcomed the technical breakthrough but say the environmental claims still need to be independently verified. While synthetic graphite can offer improved purity and performance compared to natural sources, producing it typically involves energy-intensive processes and high-temperature furnaces. Without a full lifecycle assessment, it’s unclear whether ExxonMobil’s version offers a lower carbon footprint overall.

Some environmental groups have also expressed concern that the announcement could serve as a reputational tool, allowing the company to appear aligned with energy transition goals while continuing high levels of oil and gas production. ExxonMobil has faced ongoing criticism over its lobbying record and past delays in embracing renewable energy.

Barriers and Uncertainties Ahead

Despite the positive headlines, several hurdles remain. For example, the synthetic graphite market is highly competitive, and pricing pressure from natural sources remains a factor. Regulatory alignment, especially for battery materials used in vehicles sold in the EU and UK, may require third-party certification and data disclosure.

ExxonMobil also acknowledged risks around market timing and tax incentives. In a recent comment about its hydrogen and ammonia plans, Woods warned that changing government policy could create uncertainty for long-term investment.

“We can’t do it on charity,” he said, referring to the limited duration of US tax credits under recent legislation.

Even so, the company appears to be betting that its scale, technical experience, and control of the supply chain will allow it to succeed where others have struggled.

What Does This Mean For Your Organisation?

What happens next depends on how effectively ExxonMobil can scale up production and prove the performance gains it is promising. If the material lives up to expectations, it could give battery manufacturers and vehicle makers access to a more stable, domestic supply of high-performance anode material, especially in markets looking to reduce dependence on China. That includes the UK, where securing critical minerals and battery components has become a growing concern for both government and industry. A reliable source of synthetic graphite with lower volatility and consistent quality could support EV production, battery research, and even domestic energy storage projects.

For UK firms involved in automotive manufacturing, advanced materials, or clean energy systems, this may open up opportunities for new partnerships or supply arrangements, particularly if ExxonMobil’s product proves compatible with emerging battery chemistries. At the same time, UK businesses developing their own alternatives will likely face growing competition from larger, vertically integrated players able to produce materials at scale and integrate them into existing logistics and refining networks.

ExxonMobil’s move appears to signal that legacy energy companies are looking for viable routes into clean tech supply chains without abandoning their core expertise. Whether this is seen as genuine innovation or simply an extension of fossil-based operations will depend on the transparency of the data that follows. If the environmental claims can be substantiated and the product delivers on cost and performance, it may set a new standard for what synthetic graphite can do. If not, the gap between energy transition rhetoric and reality may widen even further.

Either way, the development adds some momentum to an increasingly strategic part of the EV supply chain. For governments, manufacturers, and consumers alike, a more competitive graphite market could bring welcome improvements in performance, pricing, and resilience. However, it will also bring new questions about sustainability, transparency, and where the true value in the battery industry really lies.

Sustainability-In-Tech : New Industry Powered By EV Battery Recycling

Posted on by Paul Stradling

As electric vehicle usage expands, the race is on to recycle their batteries and recover scarce materials like lithium, nickel and cobalt, thereby cutting emissions and easing dependence on mining.

A New Phase In the EV Revolution

With global sales of electric vehicles (EVs) topping 14 million in 2023, a 35 per cent increase on the previous year, attention is now turning to what happens when those vehicles reach the end of their life. The answer lies within a growing industry focused on recycling EV batteries and recovering the valuable metals they contain.

According to the International Energy Agency (IEA), more than 40 million EVs were on the roads worldwide by the end of 2023. Yet while these vehicles eliminate tailpipe emissions, their batteries pose new sustainability challenges. The raw materials used to make them, especially lithium, cobalt, nickel and graphite, are limited, unevenly distributed around the world, and often extracted in environmentally and socially problematic conditions.

This is where EV battery recycling comes in: a critical step not just for sustainability but for securing supply chains, lowering costs, and reducing dependence on virgin mineral extraction.

Why Recycle EV Batteries?

Each lithium-ion EV battery contains a tightly packed structure of anodes and cathodes, typically made from graphite and a mix of lithium, cobalt and nickel. Over time, these batteries degrade and are eventually removed from vehicles. If not properly handled, they risk leaking toxic materials into the environment or catching fire during disposal.

More importantly, without recycling, the valuable critical minerals they contain would be lost. These metals are expensive to mine and refine, and demand is expected to grow rapidly. For example, the World Bank projects that by 2050, global demand for lithium could increase by nearly 500 per cent, with cobalt and nickel not far behind.

Recycling essentially offers a more sustainable and secure alternative. By 2040, up to 50 per cent of the UK’s EV battery material demand could be met through recycling, according to estimates shared by Altilium Clean Technology, a UK-based battery recycling firm. As Dr Christian Marston, Altilium’s COO, puts it: “If we do battery recycling at scale, we can produce materials at around 20% lower cost than commercial imports—and with significantly lower emissions.”

A Circular Model Made in Britain

Altilium is an example of a company at the forefront of this movement. Based in Tavistock, Devon, with new large-scale facilities under development near Plymouth, the company has created a fully integrated recycling process that turns old EV batteries into battery-ready materials.

The heart of its process is EcoCathode™, which is a hydrometallurgical method that uses water-based chemistry instead of high-emission smelting. Here’s a brief summary of how it works:

Step 1 – Shredding

Spent EV batteries are mechanically shredded into a fine, dark powder known as “black mass”. This material contains a mix of critical metals, plastics and other by-products.

Step 2 – Acid Leaching

The black mass is soaked in a sulphuric acid solution. This dissolves the key metals (lithium, nickel, and cobalt) into a liquid form, separating them from inert or less valuable materials.

Step 3 – Graphite Recovery

Before further processing, the graphite from the anode is extracted and purified. Altilium reports a 99 per cent recovery rate for graphite, which is then reused in new anodes.

Step 4 – Metal Separation

Using a series of chemical tweaks, unwanted elements like aluminium and copper are filtered out. The remaining solution contains the valuable metals needed for new batteries.

Step 5 – Solvent Extraction

The lithium, nickel and cobalt are separated out one by one using an advanced chemical process involving kerosene and selective reagents. This allows for high-purity recovery of each element.

Step 6 – Reprocessing for Reuse

Finally, the extracted metals are refined into cathode active materials (CAM) and precursor materials, which can be fed directly back into battery production. This closes the loop by turning waste back into high-value battery inputs. The company claims this method produces 74 per cent less carbon emissions for CAM and 77 per cent less for anode materials compared to traditional sourcing. Their recycled components are already being tested at scale by the UK Battery Industrialisation Centre, with a major car manufacturer due to validate performance later this year.

“Closed-Loop” Supply Chain

Altilium’s aim is to create a “closed-loop” supply chain within the UK, keeping resources onshore, reducing dependence on foreign imports, and supporting national energy security. “We see batteries which are in this country as a strategic asset in the UK,” says Marston. “If you do the processing in the UK, you add the value in the UK.”

Who Else Is in the Race?

Although Altilium is leading in the UK, it’s certainly not alone globally. Several firms are now building out battery recycling ecosystems, each with different models and geographic strengths. These include, for example:

– Redwood Materials, founded by Tesla co-creator JB Straubel, is a major US player with sites in Nevada and South Carolina. The company focuses on recovering and refining materials like lithium, cobalt and nickel, and has established partnerships with Toyota, VW, and BMW. Redwood’s strategy is to build a full circular supply chain, reducing US dependence on imported minerals.

– Li-Cycle, based in Canada but operating facilities across North America and Germany, also uses hydrometallurgical recycling. The company reports recovery rates of up to 95% for key materials, and is working closely with US policymakers through funding support from the 2022 Inflation Reduction Act.

– Ecobat, the world’s largest battery recycler, which is pivoting from its traditional lead-acid battery work towards lithium-ion recycling. With a strong global logistics and collection network, Ecobat has been expanding its lithium battery services across Europe and the US. According to its website, the company is focused on achieving “closed-loop recycling rates” for lithium comparable to those already achieved for lead.

How Most EV Battery Recycling Technology Works

Most battery recycling processes follow similar core steps, i.e., collection, dismantling, shredding into black mass, and then separation and refinement of metals.
Older approaches like pyrometallurgy, which uses high temperatures to melt down batteries, are effective but extremely energy intensive and carbon heavy. They also tend to destroy some of the more delicate materials, such as graphite.

Newer techniques like hydrometallurgy, used by Altilium, Li-Cycle, and Redwood, rely on water-based chemical treatments. These enable much more precise separation of metals at lower temperatures, resulting in higher recovery rates and far lower emissions.

Altilium’s process, for example, uses sulphuric acid to soak the black mass, selectively precipitating out low-value metals like iron and copper before extracting more valuable cobalt, nickel and lithium. The graphite is recovered earlier in the process and reprocessed for reuse in new battery anodes. The resulting materials are refined to battery-grade purity and can be used to manufacture brand new battery cells.

Environmental and Economic Benefits

The sustainability case for battery recycling is pretty compelling. For example, according to a 2024 IEA report, recycling critical minerals could cut the need for new mining by up to 40 per cent by 2050. For the automotive industry, that means fewer emissions from extraction, processing, and transport, and less exposure to volatile global commodity markets.

Cost savings are also significant. Altilium estimates that its recycled CAM could be 20 per cent cheaper than virgin equivalents by 2035. This could reduce the overall cost of manufacturing a new EV by 5 per cent, which is quite a meaningful margin in a competitive industry where affordability remains a barrier to adoption.

Also, the environmental gains go far beyond carbon. For example, avoiding new mining means less disruption to ecosystems, fewer human rights violations, and a reduced geopolitical dependency on regions like the Democratic Republic of Congo (which currently supplies two-thirds of the world’s cobalt) or Indonesia (the top source of nickel).

Not Without Its Challenges

Despite the promise, the battery recycling industry is obviously still in its early industrial phase. As Dr Xiaochu Wei of Imperial College London points out, many firms have only recently begun scaling beyond pilot stages. Altilium’s own journey, from a modest lab in 2022 to a full-scale facility in 2025, illustrates both the speed and complexity involved.
Battery designs themselves are also a barrier. With so many chemistries in use, from lithium-iron-phosphate (LFP) to nickel-manganese-cobalt (NMC), recycling methods must be flexible enough to handle mixed inputs. Standardising designs or redesigning batteries to be easier to dismantle could help but will require coordination across manufacturers.

Greenwashing Risk

It should be noted here that there’s also the risk of greenwashing. For example, as competition intensifies, some firms may make sustainability claims that outpace their actual recovery rates or environmental impact. Regulation can help: the EU’s new Battery Regulation, due to phase in from 2025, will require specific thresholds for material recovery and recycled content in new batteries.

What Does This Mean For Your Organisation?

Recycling EV batteries at scale is starting to look not just possible but inevitable. With regulations tightening, supply chains under pressure, and emissions targets looming, the case for a circular battery economy is becoming hard to ignore. Companies like Altilium are showing that high recovery rates and lower-carbon processes can be achieved using homegrown innovation. If they succeed in scaling up production and maintaining performance, the UK could have a credible, strategic alternative to importing expensive critical minerals from volatile markets.

For UK businesses, particularly in the automotive and clean tech sectors, this opens the door to a more resilient supply chain with greater control over cost and compliance. Manufacturers looking to meet EU recycled content rules from 2025 onwards will need trusted partners, and local recyclers could offer both regulatory support and operational savings. There are also commercial advantages to be gained from marketing genuinely low-carbon products built with verified recycled inputs, which will only become more valuable as sustainability reporting requirements evolve.

The wider benefits stretch further still. Reducing the UK’s reliance on overseas mining reduces exposure to supply disruptions, ethical concerns and carbon-heavy logistics. It also supports the domestic energy transition with onshore capabilities that align with national goals on net zero and industrial growth. For stakeholders across the board, from EV manufacturers and policymakers to investors and consumers, the expansion of battery recycling signals a maturing ecosystem with real potential to deliver on sustainability promises, rather than just headline targets.

None of this, though, will be straightforward. The sector still faces infrastructure gaps, chemistry complexity and the challenge of building scale fast enough to match the rise in end-of-life EVs. However, if early leaders can maintain momentum, the next few years may see battery recycling move from pilot to pillar, a new industrial sector supporting cleaner transport, better economics and lower environmental impact all at once.

For example, real vintage vehicles typically require extensive maintenance and may not meet modern safety or environmental standards. RBW’s cars, however, provide the reliability of new vehicles, reducing the need for frequent repairs and offering features that enhance safety and convenience.

Ryan Morris, president of Meson Capital Partners and chairman of RBW, highlighted the practicality of this approach in an interview with TechCrunch back in 2023. He noted that building a classic-style car from scratch with modern electric components reduces the maintenance burden on owners, potentially expanding the market for such vehicles. “I’ve got two kids, I work a lot, I’m busy. I don’t have time to fix my car every third time I drive it,” he remarked, emphasising the appeal of reliability in today’s fast-paced world.

Economic and Environmental Impact 

From an economic standpoint, RBW and Spirit EV’s business model aims to make custom electric vehicles more affordable and accessible. By purchasing components in larger quantities and streamlining production processes, they can reduce costs compared to traditional auto restoration shops. This efficiency not only benefits the company but also makes sustainable transportation options more attainable for consumers.

Environmentally, the promotion of electric vehicles contributes to global efforts to reduce greenhouse gas emissions. As countries implement stricter regulations on emissions and encourage the adoption of electric vehicles, companies like RBW may begin to play a crucial role in facilitating this transition. By offering vehicles that are both sustainable and aesthetically appealing, RBW hopes to address environmental concerns while meeting consumer desires.

Challenges and Future Prospects 

Despite their innovative offerings, RBW and Spirit EV face challenges inherent in entering a new and evolving market. The demand for brand-new, classic-style electric vehicles is still emerging, and companies must navigate uncertainties related to consumer acceptance and market dynamics.

In an interview, Peter Swain acknowledged these challenges but remains optimistic about the future, saying, “We’re in a new market, which we’ve created. It’s pretty unique—brand-new, classic EV cars. But where’s it going to go? Let’s be honest, we don’t know exactly”. The company’s strategy involves continuous innovation and responsiveness to market feedback, positioning them to adapt as the industry evolves.

Connecting EV-as-a-Service to Sustainability 

The EV-as-a-Service model offered by Spirit EV has significant implications for sustainability. By providing resources and expertise to other manufacturers, it helps reduce the overall environmental impact of vehicle production. This collaborative approach fosters innovation and promotes the adoption of electric vehicles on a broader scale.

The future impact of their approach will likely unfold as part of the broader evolution of the electric vehicle market and its response to global sustainability goals.

Sustainability-in-Tech : New EV Batteries Charge In 5 Mins

Posted on by Paul Stradling

A new fast-charging battery technology from Nyobolt that can charge an EV battery from 10 to 80 per cent in just under five minutes has just successfully completed its first demo road test.

Live Demo 

Founded in 2019, Cambridge-based EV battery company Nyobolt has just conducted its first live road test demo of the new battery in Bedford, in front of an invited audience of industry professionals. The new battery, which was fitted to a sports car and tested over two days, achieved a range of 120 miles after four minutes. The company says this was achievable because the first four minutes are at a constant current of 500A.

Still A Success Despite Challenges On The Day 

In lab conditions, the fast-charging battery can charge from 0 per cent to 100 per cent in six minutes but on the day, factors like the hot weather, issues with the car’s cooling system, plus having to use an on-site charger (not made by Nyobolt) meant that it only charged from 10 per cent to 80 per cent in four minutes and 37 seconds. However, that is still a very impressive result considering that a Tesla supercharger takes 15-20 minutes to charge a car battery to 80 per cent. Using a 350kW DC charger, Nyobolt says its batteries can charge at twice the speed of the fastest-charging vehicles on the road without the degradation typically associated with lithium-ion batteries.

Fast Charge And Retention  

Nyobolt also points out that independent testing of its technology by a leading global OEM has confirmed that its longer-lasting (and more sustainable batteries) can achieve over 4,000 fast charge cycles, or 600,000 miles, maintaining over 80 per cent battery capacity retention. This is considerably higher than the warranties of much larger EV batteries on the road today and highlights longer-lasting performance benefit of Nyobolt’s battery technology.

Benefits 

The company says its ultra-fast charging battery eliminates slow and inconvenient recharge stops, i.e. it saves time and combats ‘range anxiety’.

In Talks With Other OEMs 

Nyobolt doesn’t intend to make its own EVs but says it is now in talks with eight OEMs about using its technology in high performance EVs.

Lighter EVs 

Nyobolt also says that the fact that the 35kWh battery pack, as tested in the EV prototype, is compact could also benefit car makers and motorists, enabling energy-efficient electric vehicles that are cheaper to buy and run, and use fewer resources to manufacture.

Nyobolt’s co-founder and CEO, Dr Sai Shivareddy says: “Our Nyobolt EV demonstrates the efficiency gains facilitated by our fast-charging, longer-life battery technology, enabling capacity to be right-sized while still delivering the required performance,” and adds “Nyobolt is removing the obstacle of slow and inconvenient charging, making electrification appealing and accessible to those who don’t have the time for lengthy charging times or space for a home charger.” 

What Does This Mean For Your Organisation? 

Nyobolt’s groundbreaking fast-charging battery technology could be transformative for various stakeholders within the EV ecosystem. For Nyobolt itself, this development not only validates their technological innovations but may well also position them at the forefront of the EV battery market. The successful demonstration in Bedford, despite the challenges faced, highlights their capability to deliver a product that can significantly reduce charging times while maintaining high performance and longevity. This achievement is likely to attract further interest from OEMs and investors (8 are interested already), accelerating Nyobolt’s growth and market penetration.

For other EV manufacturers, the introduction of Nyobolt’s technology presents both an opportunity and a challenge. The ability to charge an EV battery to 80 per cent in under five minutes sets a new benchmark in the industry and is likely to compel other manufacturers to either adopt this technology or innovate rapidly to remain competitive. This could lead to a surge in partnerships and collaborations as manufacturers try to integrate these advanced batteries into their next-generation vehicles. Also, the focus on sustainability and longer battery life aligns with the broader industry goals of reducing environmental impact and improving the overall efficiency of EVs.

The EV market as a whole stands to benefit significantly from this technological leap. The reduction in charging times addresses one of the primary concerns of potential EV buyers – range anxiety. Faster charging infrastructure will likely catalyse broader adoption of EVs, as it makes the transition from traditional petrol and diesel vehicles more seamless. The compact nature of Nyobolt’s battery packs means vehicles can be lighter and more energy-efficient, potentially lowering the cost of EVs and making them more accessible to a wider audience. This could lead to a more rapid shift towards electric mobility, reducing the carbon footprint of the transportation sector.

For EV buyers, Nyobolt’s technology promises a more convenient and user-friendly experience, i.e. the ability to recharge quickly and efficiently means less time spent at charging stations and more time on the road. This may be particularly appealing to those with busy lifestyles or limited access to home charging setups. Also, the extended battery life and capacity retention may translate to lower long-term costs and enhanced vehicle reliability. As a result, consumers can expect a more cost-effective and sustainable ownership experience, which could drive higher satisfaction and loyalty within the EV market.

Nyobolt’s fast-charging battery technology, therefore, could herald a new era in the EV industry (which needs a boost about now), offering substantial benefits across the board. From improving Nyobolt’s market position and challenging other manufacturers to elevate their offerings, to making EVs more appealing and accessible to consumers, this innovation could reshape the landscape of electric mobility in the UK and beyond. Organisations within the EV sector will, no doubt, be closely monitoring these developments and considering how to integrate or respond to this technology to stay ahead in a rapidly evolving market.

Featured Article : Tesla Robotaxi In August

Posted on by Paul Stradling

Following a fall in Tesla EV sales and profits, Tesla boss Elon Musk has announced that he’ll be unveiling a ‘Robotaxi’ on August 8 this year.

May Swap Lower Cost EV For Robotaxi 

Reports initially indicated that Mr Musk’s Tesla company would be abandoning its plans to build a lower-cost EV (the Model 2) in favour of building the ‘robotaxi’ instead using the same small EV platform that was designed to power the lower-cost EV. However, Mr Musk took to his ‘X’ platform to quash that rumour.

What Is A ‘Robotaxi’? 

The robotaxi will be an autonomous ride-hailing service but it’s not yet clear if it will resemble a typical car or a vehicle without a steering wheel or pedals.

Promised Years Ago 

A Tesla car with autonomous capabilities was first promised back in 2016 as a way for Tesla owners to make an income from their cars as part of a ride-sharing network. At the time, the idea was that owners could add their car “to the Tesla shared fleet just by tapping a button on the Tesla phone app” enabling them to make money from the car while they’re “at work or on vacation” thereby “significantly offsetting and at times potentially exceeding the monthly loan or lease cost.” 

In 2017 and 2019 the ‘robotaxi’ idea – autonomous cars as part of a ride-sharing network – was floated again. Musk then said a couple of years later that a robotaxi with no steering wheel or pedals would enter the market by 2024.

Markets Pleased 

Mr Musk’s announcement that the robotaxi will be unveiled on August 8 initially pleased the markets with Tesla (TSLA) stock closing up nearly 5 per cent shortly after.

Automated Driving Features Anyway 

Teslas already have a driver-assistance system called ‘Autopilot’ as standard, anyway. However, for an extra $12,000, owners can buy a “full self-driving,” or FSD feature. However, this does not yet enable full autonomous driving capabilities but instead adds some automated driving features.

What Makes Tesla Uniquely Able To Introduce A Robotaxi? 

In addition to the original plan for owners to be able to add their car to the Tesla ride-sharing network, and the FSD feature, other factors that make Musk’s Tesla (perhaps uniquely) able to make a robotaxi include:

– Data Collection at scale. Tesla vehicles on the road today are equipped with a suite of sensors that collect vast amounts of data on real-world driving conditions (2.5 million miles of self-driving data from customers every day). Tesla uses this data to continuously improve its Autopilot and FSD algorithms through machine learning. This crowdsourced data collection model is unique to Tesla and is a critical component of its strategy to achieve full automation.

– Vertical integration. Tesla’s vertical integration strategy encompasses the manufacturing of its own batteries, software development, and vehicle production. This control over the entire supply chain and development process allows for rapid iteration and deployment of new technologies, which is essential for the development of an autonomous robotaxi.

– Energy efficiency and operational cost. Tesla’s electric vehicles are known for their energy efficiency, which can significantly reduce the operational cost of running a robotaxi service. Lower costs could make Tesla’s robotaxi service more competitive against traditional ride-sharing services and personal car ownership.

– Innovative battery technology. Tesla’s continuous innovation in battery technology, aiming for higher energy density, longer lifespan, and lower costs, will be critical for the economic viability and sustainability of a robotaxi fleet.

– Telsla’s brand image and consumer trust. Tesla’s brand is strongly associated with innovation in electric vehicles and autonomy. This existing consumer trust and interest could, therefore, encourage quicker adoption of its robotaxi service.

What About Regulation?

Although Tesla has experience in navigating the regulatory landscape for electric vehicles and autonomous vehicles, one of the significant challenges of getting an autonomous robotaxi service on the road is likely to be whether Tesla can successfully navigate the regulatory hurdles.

Another challenge that Tesla may be faced with to get robotaxi on the road could be of a technical nature, i.e. having to add more enhanced sensors, cameras, and other equipment to enable it to achieve full autonomy.

Hype Vs Reality? 

Other more sceptical commentators have seen Musk’s announcement as perhaps just a tactic to boost share prices and keep investors focused on the future of his company by dangling a new product (and one that’s been dangled before a few times). It’s also been suggested (e.g. by Adam Crisafulli of Vital Knowledge) that it’s a case of Tesla perhaps trying to distract from the poor current EV market conditions, and that the hype may not live up to the reality.

What Does This Mean For Your Business? 

With the EV market going through a bit of a slump and with Tesla stock prices having struggled recently, the more sceptical among us could be forgiven as seeing this announcement as ‘classic Musk’, i.e. floating a new product to give things a boost.

The idea and the original vision for the robotaxi fleet dates back to 2016 but it may now be the case (although Musk denies it) that he’s going to prioritise the robotaxi over the lower-cost EV (Model 2) car.

If successful and all regulatory and technical challenges are overcome, the introduction of a robotaxi could have a number of industrywide ripple-effects. In fact, it could shake up several industries, compelling traditional automakers to fast-track autonomous and electric vehicle technologies. Ride-hailing services could see a direct threat to their business models, as robotaxis promise lower costs and potentially cheaper fares for consumers.

This new service could also impact public transportation usage, influence insurance industry standards due to changing risk profiles, and necessitate new regulatory frameworks. Urban planning may also need to evolve to accommodate autonomous vehicles, and while there could be job displacements in driving professions, new opportunities in tech and fleet management may arise.

Also, with robotaxis being electric, they could contribute to reducing transportation’s environmental footprint, aligning with sustainability goals. These ripple effects, therefore, would span across multiple sectors, prompting widespread innovation and adaptation. All that said, we’ve now got to wait a few months to see if (and how) Musk delivers on his promise.

Sustainability-in-Tech : New £4 Billion EV Battery Factory in Somerset

Posted on by Paul Stradling

Tata Group’s global battery business ‘Agratas’ has confirmed previous announcements that it will invest £4bn in a brownfield site near Bridgwater in Somerset to make it the UK’s biggest electric vehicle (EV) battery manufacturing facility.

Somerset To Be Centre Of UK’s Green Energy Revolution

Somerset Council has reported that the Agratas factory should create up to 4,000 jobs and many more as part of the supply chain and will, “put Somerset at the centre of the UK’s green energy revolution with the potential to kick-start countywide and regional economic growth and jobs”. 

The Leader of Somerset Council described the Agratas EV battery factory plans, which could see Somerset become the UK’s biggest producer of electric vehicle (EV) batteries, as “momentous and of global significance”. 

The EV factory will be built on the old Royal Ordnance Factory site, once a major employer in the area until its decommissioning in 2008. It’s been reported that the Agratas factory will be smaller, taking only 50 per cent of the land but should, by the early 2030s (production will begin in 2026), have the capacity to produce 40GWh of battery cells annually – half the EV battery manufacturing capacity for the UK’s automotive sector (enough batteries for 500,000 passenger vehicles). It’s understood that JLR and (not surprisingly) Agratas will be the first customers for the batteries.

Residents 

Agratas says it’s informing the thousands of residents around Puriton of its plans via a leaflet through the door, provision of a community WhatsApp channel for progress updates, and an introductory event in the coming weeks.

Agratas – Clean And Green Operations 

Agratas says the “world-class gigafactories” it’s building in India and now the UK unlock green growth opportunities for global customers, that it has a “sustainability-first approach” and that its operations are “accelerating the global transition to net zero.”  

Agratas points out that it’s not just the contribution of the product that will help with the climate crisis. It’s also keen to highlight how its factories (like the one to be built in Puriton, Somerset) are designed to be powered by clean sources of electricity and should include a purpose-built renewable energy plant, thereby supporting its goal of 100 per cent clean power across all its operations. In terms of a nearby (renewable) energy plant, it’s worth noting that the Somerset factory site is only 15 miles from Hinkley point nuclear power station.

Challenges 

In addition to other challenges, The United Kingdom’s ambition to be a leader in the electric vehicle (EV) market has been somewhat hampered by its lack of domestic battery manufacturing facilities (known as gigafactories). This gap has posed significant challenges and implications for the UK’s automotive industry and its transition to electric mobility, e.g. supply chain vulnerability, competitiveness and investment attraction, job creation and economic growth, meeting its environmental targets, and more.

The confirmation that a major EV battery gigafactory will be sited here has, therefore, been greeted enthusiastically by the UK government and those involved in the EV industry.

What Does This Mean For Your Organisation? 

Building an EV battery gigafactory in Somerset in the UK is likely to bring many important benefits. These include countrywide and regional economic growth and jobs – 4,000 new high-skilled green tech jobs. Also, the fact that Agratas will work with local and regional partners (e.g. Somerset Council, Bridgwater and Taunton College, and the wider Gravity Smart Campus) will mean bespoke education and training programmes with the promise of high-value local jobs for local people in the future. Also, the UK’s ambition to be a major player in the EV market will be well-served by having a battery factory here, and this will boost EV production in the UK, attract manufacturers and investment, and boost the economy.

On the green and sustainability front, the fact that Agratas has a sustainability-first approach and plans to use clean sources of electricity are clearly likely to be attractive. For residents in the Bridgwater area, which also has the first in a new generation of nuclear power stations (Hinkley Point C) being built just a few miles down the road, the EV battery site will contribute even more to the massive boost that the local economy has received in recent years.

All that said, for many people in the UK, there is still the downward pressure of a cost-of-living crisis taking priority over decisions to purchase expensive electric vehicles that don’t yet have anything more than what many would describe as a barely adequate charging network in place. Also, despite the EV factory’s sustainability and environmental focus, it should be remembered that there is still an environmental cost being paid in the mining, production, and transportation of materials including lithium, cobalt, and nickel for EV batteries, not to mention the scarcity of such materials.

Sustainability-in-Tech : Promising Lithium Breakthrough For EV Market

Posted on by Paul Stradling

Stanford researchers have discovered a simple way to boost the range of lithium metal batteries to twice the range of conventional lithium-ion batteries which could provide a massive boost to the EV market.

Lithium-Ion Batteries 

Rechargeable lithium-ion batteries (LIBs) are currently used in a wide array of electronic devices, including smartphones, laptops, tablets, power tools, portable speakers, drones and (importantly) electronic vehicles. Although they have a high energy-density and longer lifespan compared to many other types of rechargeable batteries, scientists have been testing a variety of new materials and techniques to improve the lifecycle of the kind of batteries needed to push forward with electric vehicle (EV) ambitions.

Lithium Metal Batteries 

Lithium metal is thought the be a serious next-generation contender for EV batteries and they are different from lithium-ion batteries in that (as the name suggests) they contain lithium in its metallic form. One of the key advantages is that lithium metal batteries can go 500 to 700 miles on a single charge, which is twice the range of conventional lithium-ion batteries in EVs today.

Issue 

However, one major issue (until now) of lithium metal batteries is that they lose their capacity to store energy after just a few cycles of charging and discharging. This would obviously be impractical for drivers who expect rechargeable electric cars to operate for years.

The Stanford Research Breakthrough 

Researchers from Stanford University have announced a lithium metal battery breakthrough that is both low-cost and simple and could double the range of electric vehicles. During their research, they discovered that by simply resting the battery in the discharged state, lost capacity can be recovered and cycle life increased. The researchers say that this improvement can be made just by reprogramming the battery management software, with no additional cost or changes needed for equipment, materials, or production flow.

Discharge And Rest 

The researchers highlighted how repeated charging and discharging of a lithium metal battery results in the build-up of additional dead lithium with solid–electrolyte interphase (SEI) around it. This causes the battery to rapidly lose capacity.

Using lessons learned in previous research they found that completely discharging the battery so there is zero current running through it, and resting it in the discharged state (for just one hour) strips the metallic lithium from the anode and dissolves away some of the SEI matrix (surrounding the dead lithium). This means that once the battery is recharged, the dead lithium can reconnect with the anode (the solid SEI matric mass is no longer in the way).

The result is that the dead lithium comes back to life, thereby enabling the battery to recover lost capacity, generate more energy, and extend its cycle life.

Given that the average (American) driver spends about an hour behind the wheel each day, the researchers say the idea of resting a car battery for several hours is, therefore, feasible.

Guide For Future Studies 

The research report’s senior author Yi Cui, a professor of energy and engineering in the Stanford Doerr School of Sustainability said of the findings:

“Lithium metal batteries have been the subject of a lot of research,” and “our findings can help guide future studies that will aid in the advancement of lithium metal batteries towards widespread commercial adaptation.” 

What Does This Mean For Your Business? 

This latest rechargeable EV battery research combined lessons learned from previous research and this new research to reveal a low-cost, simple way to potentially double the range of an EV battery. The range anxiety of EV drivers has been one of several factors that has limited the growth of the EV market, so this simple solution could have a major positive influence on EV sales and use. This, in turn, has positive implications for reducing our reliance on fossil fuels, thereby helping to tackle global warming and meet emissions targets.

That said, as acknowledged by the Stanford researchers, more research needs to be done. Also, there’s also the matter of the environmental damage created by lithium mining to consider, and research is currently being carried out into many different non-lithium-based battery technologies such as sodium-ion batteries, and calcium-ion batteries. Also, organic rechargeable batteries, which are transition-metal-free (other metals used in LIBs), eco-friendly, and cost-effective could potentially address the environmental and economic concerns associated with the widespread use of transition metals in batteries.

Although the recent Stanford breakthrough is promising, there’s still some way to go in terms of finding cost-effective and sustainable EV batteries that provide the required performance levels.

Sustainability-in-Tech : Green BT Street Cabinets To Become EV Charging Points

Posted on by Paul Stradling

In line with the government’s aim to increase the number of electric vehicle (EV) charging points from 50,000 to 300,000 by 2030, the BT Group has announced that it will be repurposing its old, green street cabinets to EV charging points.

60,000 New EV Charging Points 

The move, as part of a pilot scheme beginning in Scotland “in the coming weeks” will see BT’s end-of-life green street cabinets being repurposed to add 60,000 new chargers nationwide.

Green Boxes 

BT’s green boxes, a familiar sight on many streets, have traditionally been used to house cabling for phone lines and broadband but BT says the cabinets are slowly becoming obsolete as fibre-optic broadband is rolled out across the country. The company says that when the boxes reach the end of their life the old broadband equipment can be recycled, and EV points housed there instead.

Easy To Repurpose 

The BT Group says green boxes can be converted simply by using a small device to supply renewable energy to an on-street charging point, without the need to create a new power connection. The technology can actually be deployed in cabinets which are either in use or due for retirement.

Huge Step 

Tom Guy, Managing Director at BT Group said: “Our new charging solution is a huge step in bringing EV charging kerbside and exploring how we can address key barriers customers are currently facing.” 

Other Ideas 

An insufficient number of charging stations and whether charging points are available at home (or at work) have long been seen as major challenges to the growth of EV ownership in the UK (along with other factors like the price of EVs).

Some of the many suggestions for other potential kerbside solutions include:

– Lamp posts, especially in residential areas where traditional charging stations might be impractical, and they already have an electrical connection, which can be modified to include charging points.

– Parking meters. This would save space plus make use of the existing power supply and payment systems.

– Utility poles (similar to lamp posts), which have an existing power supply and are widely distributed, making them a viable option for EV charging.

– Street furniture such as benches, bus shelters, or other street furniture with integrated solar panels which could be equipped with charging capabilities.

– Retired/classic telephone boxes (only available now in some areas) can (and have been) repurposed as EV charging points, combining cultural heritage with modern technology.

– Bollards could be equipped with charging technology.

– Public toilets, which have been getting scarcer due to closures from council cuts, already have electricity for lighting and heating, and could be adapted to include EV charging points.

– Solar-powered recycling bins with built-in Wi-Fi and charging capabilities are one suggestion of an innovative way to combine waste-management and EV charging.

– Pop-up, temporary charging hubs / mobile charging stations, in areas with high demand, using existing power sources or portable generators.

What Does This Mean For Your Organisation? 

The innovative repurposing of BT’s green street cabinets essentially kills two birds with one stone, breathing new life into old infrastructure while tackling the UK’s lack of EV charging points. It’s one step in the right direction towards sustainable technology and environmental responsibility and it sounds as though it has the potential to make a major contribution (60,000) to the UK’s target of having 300,000 EV charging points by 2030. However, bear in mind that this is still only a pilot scheme.

It also seems like quite a practical option for a broad segment of the population. For organisations operating in the EV sphere, this expansion could also open new avenues for growth and innovation, as the increased infrastructure will likely stimulate demand for electric vehicles.

Environmentally, the repurposing of existing structures for EV charging aligns with green initiatives and carbon reduction goals and utilising existing assets, such as BT’s green boxes, is a way to reduce the environmental impact of constructing the necessary new EV charging stations in the UK. It also highlights how sustainability can be achieved through intelligent innovation, rather than just new construction.

Exploring the other potential kerbside solutions, like integrating charging capabilities into lamp posts, parking meters, and even public toilets, underscores the potential for creative solutions to the EV charging challenge. A versatile approach like this could well be the key to meeting the challenge of insufficient charging points in a faster, more affordable way at scale.

However, it’s still important to acknowledge that there are other remaining challenges within the EV market, such as the high initial cost of EVs, the need for widespread adoption of renewable energy sources to truly realise the environmental benefits of EVs, and the technical challenges associated with rapidly scaling up EV charging infrastructure. Addressing these issues requires a concerted effort from both the private and public sectors, with continued innovation and investment in sustainable technologies being paramount.

That said repurposing BT’s green street cabinets, alongside other innovative kerbside solutions, could offer a blueprint for how we can meet our environmental targets while fostering the growth of the EV market in the UK.
