New insight into how lithium-rich cathode materials for high energy EV batteries store charge at high voltages

High energy storage batteries for EVs need high capacity battery cathodes. New lithium-excess magnesium-rich cathodes are expected to replace existing nickel-rich cathodes but understanding how the magnesium and oxygen accommodate charge storage at high voltages is critical for their successful adaption. Research led by WMG, University of Warwick in collaboration with U.S. researchers employed a range of X-ray studies to determine that the oxygen ions are facilitating the charge storage rather than the magnesium ions.

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.

Revolutionising the manufacturing industry through digitalisation

Until now, smaller manufacturing companies have missed out on the productivity benefits of digital technologies and data-driven solutions. Too many manufacturers don’t know where to start, and lack the skills required to deploy and use digital solutions. The costs are perceived to be high and the return on investment is unclear. A consortium, including WMG at the University of Warwick, has been awarded funding through the Government’s Manufacturing Made Smarter Challenge to tackle this problem by developing a Smart InforMation PLatform and Ecosystem for Manufacturing (SIMPLE).

High-rate Li-ion batteries demonstrate superior safety

As the inevitable growth of transport electrification continues, the types of batteries that will be used in such vehicles, their charging parameters, infrastructure and timeframes are key considerations that will speed up the transition to electrification. In the paper, Determining the Limits and Effects of High-Rate Cycling on Lithium Iron Phosphate Cylindrical Cells’ published in and on the cover of the Journal Batteries, researchers from WMG, University of Warwick investigated the impacts on battery cell ageing from high current operation using commercial cells.

Battery ageing model developed by WMG to support all-electric vehicles

Extensive research, carried out by researchers from WMG, University of Warwick included characterisation, performance, safety and degradation testing of an EV battery, with degradation being the key focus to understand the impact on battery pack warranty.
