Stanford study finds charging Li-ion cells at different rates boosts the lifetimes of EV battery packs

Green Car Congress

Stanford University researchers have devised a new way to make lithium-ion battery packs last longer and suffer less deterioration from fast charging. It was later explained that the million-mile battery concept was not really a new chemistry, but just a way to operate the battery by not making it use the full charge range. Resources.
