Canadian Light Source CT scans also reveal that electrolyte liquids inside the battery are sucked into the expanded pore space created by microcracked positive electrode materials. CLS PHOTO
THE Journal of the Electrochemical Society recently published research from the Canadian Light Source (CLS) of the University of Saskatchewan, which showed how the charge/discharge cycles of batteries cause physical damage eventually leading to reduced energy storage. This new work points to a link between cracks that form in the battery material and the depletion of vital liquids that carry the charge.CLS researcher Toby Bond used X-rays to help engineer powerful electric vehicle batteries with longer lifetimes. Bond used the BMIT facility at CLS to produce detailed CT scans of the inside of batteries. Working with…
