Solid-state batteries could be made more cleanly by scaling-up flash sintering

Densifying ceramics using flash sintering reduces energy use and may be used to improve the viability of manufacturing complex ceramic structures such as those required for solid state batteries by lowering the temperatures and shortening the duration of the heat treatment.

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.

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.

Warwick Racing team develop second electric race car during lockdown

The Warwick racing team usually spend their summer in the workshop building an electric race car, but lockdown this year due to the covid-19 pandemic didn't stop them from designing and virtually validating a second electric car, WRe2, and racing their original car WRe1 virtually.
