The SafeBatt project, involving battery experts from WMG at the University of Warwick, has won a Safety Innovation Award at the Electrical Product SafetyLink opens in a new window Conference. 

The conference was held in London on Thursday (21^st November) with the awards recognising and celebrating the best engineering collaborations and innovations across the UK. 

Funded by the Faraday Institution, SafeBatt is a collaboration of seven universities as well as industry partners investigating the science behind battery safety.  

The University of Warwick is shedding the light on a distinguished battery researcher this International Day of Women and Girls in Engineering.

Dr Melanie Loveridge, Reader in Battery Materials and Cells at WMG at The University of Warwick, is also committed to improving the inclusivity of women and minority groups in her area of work. Her research focuses on lithium-ion batteries, helping to power net zero and a more sustainable world.

Dr Loveridge said: “The first lithium-ion batteries were used in small Sony cameras, now we are relying on them to power electric vehicles. We need much bigger sources of power to last longer, which has been a significant challenge.

“I conduct forensic analysis of batteries to help understand how they degrade over time, which is really important in knowing how to improve the way we manufacture them. Understanding why batteries fail is crucial, as the world shifts to more sustainable energy sources.

“My team uses specialised equipment such as electron microscopy, Xray based characterisation and mapping chemical elements in materials to look at the components within batteries under high magnification. Battery forensics needs a huge orchestra of highly sophisticated techniques.”

Starting her career in the industry, Dr Loveridge became fascinated with the science of batteries and decided to pursue an academic role to learn more. This has led to her publishing over 40 academic papers.

With over 15 years’ experience in academia, she has also given evidence from for her research specialisms for influential panels such as the House of Lords Science & Technology Committee and The Shadow Cabinet’s Round Table on Energy Storage.

Dr Loveridge added: “My research area is such a multidisciplinary field. I can interact with engineers and scientists from across many academic disciplines and industry partners, which is not commonplace in a lot of academic circles. It’s amazing to collaborate with lots of different people.”

Alongside her academic achievements, Dr Loveridge champions equality, diversity and inclusion (EDI) in her work. She has recently been appointed as Associate Dean of Research – where she is supporting an enhancing culture project funded by The University of Warwick, on a survey-led initiative with an aim to understand the challenges and barriers faced by minority groups and women in leading STEM-based research.

“Fortunately, lots of the funders I work with, such as the Faraday Institute, really value diversity and inclusion; we now have to show how we have outlined commitments to EDI in all of our grant applications. I think the gender imbalance in senior roles will change, but this will take time.

"As part of my EDI role, I’m also trying to make the working environment more inclusive, particularly for special interest groups. I find this really rewarding.”

By championing sustainable research, such as Dr Loveridge’s vital work on batteries, The University of Warwick is committed to creating a more sustainable world. Its Strategy 2030 sets out five key sustainability pathways to follow, including achieving Net Zero carbon emissions from scopes 1 and 2 by 2030, and scope 3 by 2050.

The University of Warwick has been awarded millions of pounds to boost British production of crucial materials for electric car batteries.

The £12 million in funding has been awarded by the Faraday Battery Challenge to the High Value Manufacturing Catapult at WMG at the University of Warwick, and CPI at NETPark (North East Technology Park), in County Durham.

It will be used to create the new Advanced Materials Battery Industrialisation Centre (AMBIC).

The Centre will bridge the gap between academic research and battery production and will focus on how batteries can be made to work more efficiently, as well as on equipment and skills development.

The Centre is needed to help the UK develop the electric vehicle batteries of the future, with reduced costs, more sustainable materials and improved performance.

Electric vehicle batteries make up around half the cost of a new electric vehicle, so reducing the cost of their production is crucial to lowering the cost of EVs to parity with combustion engine vehicles.

The funds are part of a wider investment strategy by the Faraday Battery Challenge and the High Value Manufacturing Catapult to ramp up Britain’s battery production and infrastructure to boost the UK’s domestic battery supply chain.

Professor David Greenwood, CEO of the WMG High Value Manufacturing Catapult Centre said: “Cathode and anode active materials make up more than 50% of the value of an automotive battery cell.

“For the UK to take its great academic research into production, and to capture the billions of pounds of resulting economic value in the UK, we need facilities which allow Britain to scale up and fully evaluate new materials. This investment, alongside the combined skillsets of CPI and WMG will provide that capability for the UK.”

The funds are specifically to help turbocharge the scale up of battery materials manufacturing within the UK. Only by producing batteries on a wider scale domestically can the EV industry make sure there is no bottleneck in supply and demand. By strengthening UK supply chains of battery materials, WMG is working with UKBIC and others to create a more resilient supply chain.

Thomas Bartlett, Challenge Deputy Director for the Faraday Battery Challenge, said: “AMBIC will bring together two emerging regions of battery innovation and manufacturing; the North-East and Midlands, under one facility to de-risk and accelerate battery materials scale up in the UK.

“Through the Faraday Battery Challenge’s £12m investment in the High Value Manufacturing Catapult we will establish a truly world-class facility to support the growth of a battery materials supply chain. With AMBIC and previous investments in cell, module and pack scale-up at UKBIC and R&D in the wider ecosystem, the UK will now be in a position to support businesses from “powder to pack” and from lab to commercial scales.”

Katherine Bennett, CEO of the High Value Manufacturing Catapult, said: “The next generation of battery technologies are critical to the green energy transition and a major opportunity for UK manufacturing. Realising that potential will require combining our collective expertise and this investment from the Faraday Battery Challenge is a brilliant example of that in action.

“In CPI and WMG, the Advanced Materials Battery Industrialisation Centre has two centres that are at the very forefront of chemical processing and battery cell development; together they can turbo charge battery materials scale-up.”

Frank Millar, Chief Executive Officer at CPI, said: “The Advanced Materials Batteries Industrialisation Centre will enhance the UK’s existing competitive advantages in batteries technology, and it stands to become a catalyst for the UK to address some of the biggest challenges we face as a nation. By giving innovators the opportunity to harness our expertise we can tackle issues such as climate change, while growing a sector that will be vital to the future of the economy.”

WMG, at the University of Warwick, has received a share of £19 million from the Faraday Institution - the UK’s flagship institute for electrochemical energy storage research.

The funding has been allocated to four key battery research projects aimed at delivering an impact for the UK. These existing projects across three different research areas — next generation cathode materials, electrode manufacturing and sodium-ion batteries — have been reshaped to focus on the areas with the greatest potential for success.

WMG is taking a key role in two of the four, reshaped projects entitled FutureCAT and Nextrode.

WMG’s Professor of Battery Innovation, Louis Piper, will now co-lead FutureCAT, a battery cathode research project, focusing on understanding novel redox processes as a route to stabilise both high capacity, high performance, nickel rich and emerging cathodes and scalable designer morphologies. The project will build on its success in developing reliable, scalable routes to deliver a longer lifetime, high-energy/power cathodes, essential for electric vehicles.

Whereas in Nextrode, a battery electrode project, WMG is one of six university partners, led by the University of Oxford, alongside six industry partners. Researchers at WMG will investigate ways to make electrodes for Li-ion batteries unlocking the electrochemical potential.

Professor Pam Thomas, CEO, Faraday Institution, commented: “The Faraday Institution remains steadfast in its commitment to identify and invest in battery research initiatives that hold the greatest potential for making significant societal, environmental, and commercial contributions. This announcement signals the completion of our latest round of project refocusing, enabling us to allocate even more effort towards those areas of research that offer maximum potential in delivering transformative impact.”

James Gaade, Research Programme Director commented: “We are pleased that the reshaping process has bolstered the capabilities and expertise of researchers on the four projects. The realignment includes a focus around research into sustainable manufacturing methods and materials, and the need to further develop and scale up manufacture of promising materials discovered in the first three years of the projects.”

FutureCat – High nickel content, high performance cathode materialsLink opens in a new window 

FutureCat, co-lead by WMG’s Professor Louis Piper, and the University of Sheffield’s Professor Serena Cussen is targeting step-changes in:

• Understanding novel redox processes as a route to stabilise both high capacity, high performance, nickel rich and emerging cathodes. The project continues its focus on doped and dual-doped lithium nickel oxides (LNO) (both polycrystalline and single crystals), including use of protective coatings. The team will also investigate the use of polyanionic cathodes, use modelling to inform the search for new candidate materials, and research designer electrolytes with the intention of stabilising the interphase layer.
• Scalable designer morphologies. The project will build on its success with doped-LNO in developing reliable, scalable routes to deliver a longer lifetime, high-energy/power cathodes through the use of gradient morphologies, co-doped cathodes (with the aim of delivering reversible discharge capacities exceeding 220 mAh/g), single crystal particles and thin coatings.
• Materials delivery: The scale up of the high nickel W-LNO material previously developed by FutureCat is being transferred to the Degradation project for testing in industry-relevant pouch cells. FutureCat will continue to investigate the manufacturing scale-up of other Ni-rich cathode materials, down-selecting promising active materials based on earth-abundant elements. Research includes the use of laser patterning to increase power densities, investigation of cracking as a failure mechanism to determine routes to resilient cathode manufacture, atomic layer deposition of coatings to improve electrode longevity, and optimisation of cycle life through the use of electrically conductive binders.

Nextrode – electrode manufacturingLink opens in a new window 

Nextrode is focused on researching, understanding and quantifying the potential of smart electrode manufacturing to reduce manufacturing costs and improve the performance of batteries. Benefits could be realised in both mature material systems already used commercially and in new emerging high performance battery systems. The project is developing new practical manufacturing innovations – including traditional slurry cast electrodes and novel low or no solvent electrodes – that could deliver the benefits of smart electrodes to the industrial scale and improve sustainability of processes.

The project is researching the underpinning manufacturing science that could alleviate constraints in electrode manufacturing through engineering particle design and improved understanding of the relationship between powder properties and deposition/calendering techniques. Nextrode is designing manufacturing process steps and using advanced in-line measurements to enable slurry casting to be brought under closed-loop control. Researchers are manufacturing new arrangements of anode and cathode materials, identifying conditions where benefits are maximised and developing cells that expand the energy-power-lifetime design space.

The new phase of research projects described will progress over the two years from 1 October 2023 to 30 September 2025.

Researchers at WMG, University of Warwick’s Forensics & Advanced Characterisation of Batteries Group, have secured £1.5m funding for materials analysis in multiple format batteries.

The funding, from the University of Warwick’s Academic Equipment Fund and the High Value Manufacturing Catapult, will be used to purchase a Plasma Focused Ion Beam (PFIB) microscope. The microscope is key to the accelerated development of new battery chemistries, providing unique access to the critical interfaces within battery cells that dictate best performance. This will be instrumental in developing new materials for better batteries, regardless of their end use application.

This PFIB will be the first specifically configured microscope dedicated to battery research in the world, allowing researchers at WMG to inform battery manufacturing, answer key scientific questions and link with industry and growing supply chains.

There is increased recognition in the battery community that the integration of new chemistries needed for the UK Government’s 2030 electric vehicle battery targets will require integrating new manufacturing processes with advanced microscopic characterisation. The PFIB has been specifically designed to address the critical challenges of studying alkali-based battery systems and will provide unique insights needed for the development of next generation batteries.

The performance of battery materials is dictated by the stability, efficiency and functionality of the interfaces, i.e. the solid electrolyte interphase (SEI) at the anode and oxygen-induced cathode-electrolyte interface (CEI) at the cathode. Attempts to analyse these interfaces, in order to determine structure and chemistry, is seriously compromised using conventional techniques by the extreme air-sensitivity, beam sensitivity and the high volatility of certain species present. The specially configured PFIB microscope will address these issues.

WMG is one of seven HVM Catapult centres in the UK and is the lead centre for transport electrification. Investment in this PFIB is part of a range of equipment investments by the HVM Catapult and the University of Warwick to maintain WMG’s leading position in battery technology.

The PFIB has already secured interest from the Faraday Institution and from the Royal Academy of Engineering’s Lord Bhattacharyya Education Programme. Starting in the Autumn, a student will use this for a project entitled “The development of a new multi-modal capability for investigating the performance-controlling interfaces and microstructures that underpin operation of battery materials.”

The Lord Bhattacharyya Education Programme provides up to 90 bursaries annually for local students from lower socio-economic backgrounds. The objectives for the scheme include encouraging a greater number of young people from a more diverse range of backgrounds, raising their aspirations and skill levels. Moreover, it supports the growth of a science and engineering skills base for the UK.

The project will make extensive use of the new system to develop strategies for studying the degradation of buried interfaces and structure dynamics in state-of-the-art high Ni NMC cathodes as a function of cycle ageing i.e., the evolution of the cathode-electrolyte interphases. The platform provides some unique opportunities for developing powerful new ways to characterise these controlling interfaces and will form the basis for the project. Preliminary research will commence in October 2023. The project will be advertised online for interested applicants to apply – the studentships page, Jobs.ac.uk, FindAPhD.com and the Doctoral College website.

New research has shown that understanding how oxygen participates in energy storage is critical for developing higher energy density batteries, in a new paper published by experts at WMG, at the University of Warwick.

Using advanced X-ray techniques, researchers at WMG, together with the Faraday Institution's FutureCat consortium, have obtained new insights into the oxygen redox activity in conventional ni-rich cathodes, which will help to deliver improved electric vehicle performance.

Range anxiety is a key concern of many potential EV buyers, but range is steadily improving as battery technology and research evolves. The Faraday Institution’s Next Generation Lithium-Ion Cathode Materials project, FutureCat, aims to develop understanding of existing and newly discovered cathode chemistries to deliver improved EV performance, whilst considering sustainability.

Professor Louis Piper, from WMG at the University of Warwick, who led the research explained: “Transitioning to electrification requires integrating advanced materials science into battery processing to develop cheaper, safer, faster and better batteries, which is the focus of our research.”

The battery field is moving to increasing nickel contents in cathodes to meet the Government’s stringent EV 2030+ targets. These roadmaps assume successful strategies in material development to allow cathodes like W-LNO to operate at high voltages without degrading. This work provides the platform towards realising that goal by better understand the redox mechanisms (i.e., the reactions that enable charging/discharging the battery) at high voltage operation.

The study employed advanced x-ray characterisation techniques at the Diamond Light Source in Oxford and at WMG. The team at WMG utilised novel in-house x-ray absorption spectroscopy which enabled researchers to look at the electrode redox process of the battery cathodes after careful disassembly. Researchers were surprised to find that the oxidised oxygen species had the same characteristics as another group of Li-ion battery cathodes, Li-excess transition metal oxides. Reconciling how the same oxidised oxygen environment exists in both conventional and Li-excess cathodes is critical for unlocking how to develop the next generation of cathodes.

Professor Piper adds: “This work highlights how large-scale collaborative fundamental studies are needed even for supposedly ‘known’ systems.”

WMG will be continuing with further studies in this field, supported by the Faraday Institution, for the benefit of cathode battery manufacturers.
