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.
They used two tests to establish the maximum current limits before cell failure and applied this maximum current until cell failure. Testing was performed to determine how far cycling parameters could progress beyond the manufacturer s recommendations.
