The adoption of electric vehicles has created a huge demand for battery metals such as lithium, nickel and cobalt; and this will accelerate each year as electric vehicles replace conventional vehicles. UK-based OEMs pay hundreds to recycle end-of-life lithium-ion batteries that are then exported abroad for material recovery, with the material later repurchased. Recycling of batteries in the UK will provide a stable and sustainable supply of indigenously sourced metals that will be vital for the UK’s automotive needs.
Anwar Sattar, Lead Engineer at WMG, explains: ‘‘The UK has some of the best research organisations in the world, and this facility will now enable us, like our international peers, to take our innovations to the EV market direct.
“We can now carry out kilogramme scale research which will allow us to attain data that is much more valuable to the UK industry, allowing them to make informed decisions about issues such as material handling and separation, scalability, product quality and waste production.’’
Professor David Greenwood, CEO of the WMG Centre HVM Catapult and Director of Industrial Engagement adds: “Batteries are a key enabler to the use of zero carbon energy, and they are a great industrial opportunity for the UK. Making them uses significant quantities of valuable materials, so it is essential that they are safely collected and recycled at the end of their useful life – providing the material feedstock for future generations of batteries. Today’s processes recover as little as 50% of the mass of the battery, and require large quantities of energy and chemicals as inputs. This new facility at WMG will allow us to research new recovery techniques which are more effective, cleaner and cheaper to operate.”
The new recycling facility, funded by the High Value Manufacturing Catapult, is situated within the Advanced Materials Manufacturing Centre. It is equipped with state-of-the-art equipment such as a wet alkaline scrubber which will enable researchers to safely carry out experiments that are not possible elsewhere. It is designed to accommodate pilot scale recycling machinery including dryers, furnaces, separators, and various reactors for the chemical recovery of metals. The facility will also host a scaled-up version of WMG’s novel lithium recovery process which will be able to recover over 90% of the lithium in a battery at very high purities.
Various projects are already underway at the facility including an £8.9m project ‘Recycling of EV Cells from Obsolete Vehicles at Scale’ (RECOVAS). Supported by the Advanced Propulsion Centre, the project will create a circular supply chain for electric vehicle batteries in the UK.

MOU signed between Johnson Matthey, Faraday Institution, Britishvolt, Oxford University, UK Battery Industrialisation Centre, Emerson & Renwick and University of Warwick
HARWELL, UK (19 August 2021) A consortium of seven UK-based organisations has signed a memorandum of understanding to combine ambitions to develop world-leading prototype solid-state battery technology, targeting automotive applications.
Solid-state batteries offer significant potential advantages over conventional lithium-ion batteries and could be transformational in meeting the UK’s net zero commitments through the electrification of transport. The successful outcome of the collaboration would be to harness and industrialise UK academic capability to produce cells using highly scalable manufacturing techniques that leapfrog the cost-effectiveness and performance achieved elsewhere.
The consortium comprises the following world-leading organisations in battery research, development and manufacturing:
· Faraday Institution – the UK’s independent institute for electrochemical energy storage research, which has led the consortium’s formation and will lead its development.
· Britishvolt – the UK-based Gigaplant developer, with a site in NE England.
· E+R (Emerson & Renwick) – a world leading designer of manufacturing equipment.
· Johnson Matthey – a global leader in sustainable technologies and the UK’s leading battery materials business.
· Oxford University – that leads the Faraday Institution’s solid-state battery project (SOLBAT) and provides the necessary scientific understanding to the consortium.
· UK Battery Industrialisation Centre – the pioneering battery manufacturing development facility to enable UK battery manufacturing scale-up and facilitate upskilling in the battery sector.
· WMG, University of Warwick – leaders in battery R&D and initial scale-up capability, as well as academic and apprenticeship skills development.
The preliminary design for a prototyping facility has been developed. Sources of funding are currently being sought.
Minister for Investment Lord Grimstone said: “Collaboration between industry, government and our world-leading academic institutions is putting the UK at the forefront of global efforts to develop innovative automotive technologies, such as solid-state batteries.
“It is the work of our internationally-renowned research and development base, like those brought together by this consortium, that will give us the tools needed to forge a strong and sustainable future for the automotive sector and increase our contribution to combatting climate change.”
“I am delighted to be able to announce the formation of this unique consortium for the advancement of solid-state battery prototyping that includes leading UK-based organisations at many stages in the value chain,” said Professor Pam Thomas, CEO of Faraday Institution. “Our leadership in this venture signals a move towards a role that the Faraday Institution will increasingly play as a trusted convener of significant partnerships between UK industry and academia as a route to commercialise breakthrough science emerging from our research programmes to maximise UK economic value.”
Solid-state batteries (SSBs) offer significant potential advantages over existing lithium-ion battery technologies, including the ability to hold more charge for a given volume (leading to increased electric vehicle (EV) range) and reduced costs of safety-management. Early deployment of SSBs is likely to be in consumer electronics, niche automotive applications and unmanned aerospace, before being used in broader EV markets. The Faraday Institution forecasts that, in 2030, SSBs are likely to take a 7% share of the global consumer electronics battery market and a 4% share of the EV battery market. Global SSB revenues from sales to EV manufacturers are expected to reach $8 billion by 2030 and then grow rapidly to 2040 and 2050 when the market is expected to become extensive.
However, there are fundamental scientific challenges that need to be addressed before high power SSBs with commercially relevant performance can be realised. The Faraday Institution’s SOLBAT project has made considerable progress in addressing these challenges over the last three years.
The construction of the one-of-a-kind facility being developed by the collaboration will enable SSB technology to emerge from UK university laboratories. It will allow larger cells to be produced using scalable manufacturing techniques that will be improved iteratively through deep investigation of the causes of problems that emerge during manufacture and testing of prototype batteries. This will leverage the collective knowledge of Faraday Institution SSB researchers and the industrial partners.
Christian Gunther, CEO, Battery Materials at Johnson Matthey comments, “The realisation of a prototype solid-state battery cell will be a great achievement for the UK battery industry, and this consortium will be a critical enabler for delivering this milestone. Delivering enhanced range and safety over traditional lithium-ion battery technologies will be a key driver for battery electric vehicle adoption, supporting the transition to a net zero future.”
Dr Allan Paterson, Chief Technology Officer, Britishvolt comments, “Solid-state is the holy grail of battery solutions. Solid-state batteries have the potential to increase energy density significantly over battery technology available today and could dramatically, and positively, change the world of electric vehicles. Britishvolt will be at the forefront of commercialising this step change over the coming years. This collaboration, which includes major global industrial leaders such as Johnson Matthey and academic leadership from University of Oxford, underscores another key objective in our technology roadmap – home grown intellectual property.”
Professor Peter Bruce, Principal Investigator of SOLBAT, comments: “It’s fantastic to see the culmination of combined UK academic strength in solid-state battery research come to fruition. I’m proud that the work of the Faraday Institution SOLBAT project, led by Oxford University, will make a significant contribution to the UK’s green energy revolution.”
Ian Whiting, Commercial Director at UKBIC added: “Our newly opened national battery manufacturing scale up facility is already contracted to scale new cells and battery packs by companies basing their manufacturing centres in the UK. It’s a really exciting time for this fast-growing industry. We’re scaling technologies that will be the core products of the UK’s emergent Gigafactories. But we need to think even further ahead and solid-state battery technology is going to be a big part of that. This collaboration is what is needed to give the UK the edge it needs in creating a centre of excellence for solid-state batteries and we’re excited to be part of it. The bringing together of academic and industrial know how in this space is key to unlocking Britain’s electrified potential.”
David Greenwood, Professor of Advanced Propulsion Systems, and CEO of WMG High Value Manufacturing Catapult comments: “Early forms of solid-state battery are already around us, but we have yet to see solutions which are both mass-manufacturable and meet the performance and cost targets for future transport applications. There remains huge opportunity for innovation in this space, and this initiative will provide the route for the UK to fast-track candidate technologies to industrialisation.”
Andrew C Jack, Sales Director, E&R Group comments, “E&R Group are delighted to be contributing our world renowned engineering expertise working in partnership Faraday and the wider consortium on this exciting development for next generation battery production for the UK.
Highly efficient grid-scale electricity storage at fifth of cost – researchers modify hybrid flow battery electrodes with nanomaterials
Researchers in WMG at the University of Warwick, in collaboration with Imperial College London, have found a way to enhance hybrid flow batteries and their commercial use. The new approach can store electricity in these batteries for very long durations for about a fifth the price of current technologies, with minimal location restraints and zero emissions.
Wind and solar power are increasingly popular sources for renewable energy. Unfortunately, intermittency issues keep them from connecting widely to the National grid. One potential solution to this problem involves in the deployment of long-duration battery technology, such as the redox flow battery. Despite its great promise the current costs of this system are a key determining factor to real-world adoption. An affordable grid battery should cost £75/kWh, according to the US Department of Energy. Lithium-ion batteries, which lead the charge for grid storage, cost about £130/kWh.
Now WMG researchers have found a way of enhancing hybrid flow batteries or regenerative fuel cell (RFC) technology that could store electricity for very long durations for about one-fifth the cost of current storage technologies, with flexibility in siting and with minimal environmental impact. The technology combines carbon-based electrodes with economically sourced electrolytes, (manganese or sulphur, which are abundant chemicals in the planet) by means of a simple and yet highly effective electrophoretic deposition of nano-carbon additives (nitrogen-doped graphene) that enhance the electrode durability and performance significantly in highly acidic or alkaline environments.
The researchers have published their findings in a paper entitled, ‘Hybrid Redox Flow Cells with Enhanced Electrochemical Performance via Binderless and Electrophoretically Deposited Nitrogen-Doped Graphene on Carbon Paper Electrodes’ in the December 2020 edition of the journal ACS Applied Materials & Interfaces.
Dr Barun Chakrabarti, a Research Fellow in WMG at the University of Warwick and one of the lead authors on the paper said:
“This EPD technique is not only simple but also improves the efficiencies of three different economical hybrid flow batteries thereby increasing their potential for widespread commercial adoption for grid-scale energy storage.”
The hybrid flow battery’s total chemical cost is about 1/30th the cost of competing batteries, such as lithium-ion systems. Scaled-up technologies may be used to store electricity from wind or solar power, for multiple days to entire seasons, for about £15 to £20 per kilowatt hour. These batteries are also extremely useful for grid-scale load levelling applications as their design is very flexible due to their unique feature of sizing their power independently of their energy.
The energy density of a hybrid flow battery, especially the polysulphide/air system (S-Air), is 500 times higher than pumped hydroelectric storage. It is also so much more compact and can be placed near any renewable generation.

Background history to this area of research
Development of the EPD technology began in 2013, when Professor Low joined WMG as an Assistant Professor and researched industrial Lithium-ion battery manufacturing processes. EPD involves the migration of electrically charged particles through a fluid that is under the influence of an electric field generated by applying the right potential.
Although EPD is an industrially adopted process such as for depositing industrial coatings onto conductive substrates, its mass-scale adoption for energy storage applications has only recently seen some success. Supported by EPSRC’s First Grant (EP/P026818/1, https://gtr.ukri.org/projects?ref=EP%2FP026818%2F1) and Industrial Strategy Challenge Fund on battery and supercapacitor manufacturing (EP/R023034/1, https://gtr.ukri.org/projects?ref=EP%2FR023034%2F1), Low’s research team have developed EPD for preparing lithium-ion battery electrodes that meet industrial standards for thickness and mass loadings and published their finding in ‘Batteries and Supercaps’ (https://chemistry-europe.onlinelibrary.wiley.com/doi/full/10.1002/batt.201900017). They have also produced carbon electrodes with nanomaterials for improving the practical performance of vanadium-based flow batteries using deep eutectic solvent electrolytes, and published their finding in ‘Batteries’ (https://www.mdpi.com/2313-0105/6/3/38).

Used EV batteries could be used to power rickshaws in Bangladesh, as researchers from WMG, University of Warwick, seek to find out how they can be repurposed for the rickshaws and lower peoples’ carbon footprint.
Motorised rickshaws, also known as easy-bikes, have gained popularity in Bangladesh due to their cost-effectiveness with one million of them all over the country.
In order to reduce the carbon footprint, researchers at WMG are exploring the possibility of repurposing used EV Li-ion batteries thanks to a £25,000 grant from Global Challenges Research Fund (GCRF), an award from the UKRI aimed to deliver scalable solutions to issues faced by low and middle-income countries.
Currently, Li-ion batteries retire from EVs after reaching 70-80% of their state of health (SoH). At 70% SoH, the lithium-ion battery still have 3 times higher energy density than a new lead-acid battery, and potentially can have a lifetime of 3-5 years in easy-bike application.
The researchers hope to repurpose the batteries to improve the energy storage life from 6-12 months to 3-5 years, which in turn will reduce the number of batteries being recycled and improve the ecosystem.
The new application of Li-ion batteries will be better environmentally without an additional cost in transport. As easy-bike replaces manual driving, the quality of life will improve significantly and bring a socio-economic change to a large community in Bangladesh. Furthermore, this development could reduce the consumption of grid-connected electricity which could be used to develop industries and infrastructure.
In fact, there are currently one million rickshaw pullers in Bangladesh who earn $4.8 billion every year. The new development in easy-bikes will directly improve their economic status. A few million people involved in vehicle support such as mechanics and manufacturing industries will also be benefited.
This project eventually could lead to mass production of second-life Li-ion batteries in Bangladesh, in conjunction with UK automobile industries, which will create job opportunities for thousands of people.
Dr Mohammad Al-Amin from WMG, University of Warwick comments:
“To prevent climate change, all cars in the future will need to be electric. However, the batteries in EVs once they have reached their end of life, for car purposes, is something that can be explored more, as there is still energy left in them to be used.”
“If we can re-purpose them to be used for easy-bikes in Bangladesh it will help lower their carbon footprint and provide the country with a new economy. Thousands of jobs opportunities could be created both in Bangladesh and the UK.”

· Nextrode project could revolutionise the way electrodes for Li-ion EV batteries are manufactured
· Smart high performance electrodes could enable EVs to travel further and be more durable
· WMG at the University of Warwick will research and model new and existing manufacturing processes to unlock full potential of electrochemical materials in cells
The Faraday Institution funded “Nextrode” project, involving WMG at the University of Warwick, will research ways to make electrodes for Li-ion batteries which unlock the electrochemical potential of their ingredients.
WMG, at the University of Warwick, is one of six university partners in the Nextrode project, which is led by the University of Oxford, alongside six industry partners – including the UK Battery Industrialisation Centre (UKBIC) who will be researching how to make electrodes for Li-ion Electric Vehicle batteries more efficiently.
Today’s Li-ion batteries are made using a 'slurry casting' process, whereby the active materials are mixed in a wet slurry and coated onto thin foils of aluminium or copper, then dried and compressed. This process is highly effective for mass production, but is developed empirically through trial and error, at great cost to the manufacturer.
In this project, WMG will gain greater depth of knowledge in that process with a view to being able to predictively model and optimise it, so that future electrodes can be cheaper, store more energy, and get to market faster. To do this, WMG will use their state-of-the-art “battery scale up” facility, as well as taking data from the UKBIC when it opens next year.
Furthermore, slurry cast electrodes limit the performance of the battery as the active electrochemical materials are uniformly distributed throughout the electrode structure. Research has shown that arranging the materials in a structured way can dramatically improve battery performance, but at present there is no mass-manufacturing route to do so. This project will investigate new manufacturing methods to create structured electrodes in a cost effective way at high manufacturing volumes.
“Battery manufacturing is a critical industry for the UK to grow. It is highly competitive, and to win, we will need excellence in both science and manufacturing. The Nextrode project brings these two elements together to make future Li-ion batteries for Electric vehicles more energy efficient and affordable. Our unique research facilities are key to acquiring the knowledge required to deliver a step change in industrial capability."
Professor Patrick Grant from Oxford University who will lead project comments:
“Nextrode aims to strengthen the scientific understanding of existing electrode manufacturing so we can make it more flexible and extract further performance gains, but we will also develop a new generation of manufacturing approaches for ‘smart” electrodes where the different electrode materials are arranged with greater precision and provide even greater performance benefits. We anticipate these benefits could be realised for almost any type of battery chemistry”.
This project is just one of five that the Faraday Institution has announced today, 4th September. In total, it will award up to £55 million to five UK-based consortia to conduct application-inspired research over the next four years to make step changes in the understanding of battery chemistries, systems and manufacturing methods.
Business Minister, Nadhim Zahawi comments:
“Today’s funding backs scientists and innovators to collaborate on projects that will deliver a brighter, cleaner future on our roads. We are committed to ensuring that the UK is at the forefront of developing the battery technologies needed to achieve our aim for all cars and vans to be effectively zero emission by 2040.”
Neil Morris, CEO of the Faraday Institution comments:
“It is imperative that the UK takes a lead role in increasing the efficiency of energy storage as the world moves towards low carbon economies and seeks to switch to clean methods of energy production. Improvements in EV cost, range and longevity are desired by existing EV owners and those consumers looking to purchase an EV as their next or subsequent car. Our research to improve this web of battery performance indicators (which are different for different sectors) are being researched, with a sense of urgency, by the Faraday Institution and its academic and industrial partners. Our fundamental research programmes are putting the UK at the forefront of this disruptive societal, environmental and economic change.”
UK Research and Innovation Chief Executive, Professor Sir Mark Walport, comments:
“Bringing together experts across industry and academia, this exciting research will grow our understanding of battery chemistries and manufacturing methods, with the potential to significantly improve the UK’s ability to develop the high-performance electric vehicles of the future.
