Over the coming few years automakers will be looking to integrate Li-ion batteries with significantly improved performance into new EV models. They are looking to the research community to develop ways to improve Li-ion cell chemistry that would boost battery life, store greater energy to improve range, reduce battery cost, increase the power available to the EV during acceleration, and remove the reliance on a supply chain for cobalt over which there are significant ethical concerns. The biggest improvements in performance are likely to arise from refinements to the chemistry of the cathode.
Developing a new generation of Li-ion cathodes that meet performance requirements presents a major scientific and commercial challenge, but the benefits to automakers and their supply chain are both large and near-term. The CATMAT project represents a fresh approach to meeting these challenges.
CATMAT will place considerable emphasis on understanding the fundamental mechanisms at work within novel cathodes that currently prevent the use of nickel-rich cathodes (with low or no cobalt) and plans to exploit this new knowledge to inform the discovery of novel cathode materials with enhanced properties. It will identify the most promising new cathode materials, scaling up their synthesis and assimilating them into fully battery cells to demonstrate performance.
Milestones (to September 2023):
CATMAT’s advances in high performance cathodes will be taken forward to innovation and potential commercialisation through its industrial partners, which will provide important pathways to technological impact. Partners include leading players in the chemical, materials, cell manufacturing and automotive sectors. Their perspectives on commercialisation opportunities and technology transfer will be woven throughout the project. The project team is committed to nurturing entrepreneurship and supporting potential spin-out activity. UKBIC could potentially take forward CATMAT’s research into commercial scale demonstration, to expedite the commercialisation of promising candidates and maximise industrial impact to the UK.
