Predicting the slow death of lithium-ion batteries

In electric cars, the new technology could improve driving range estimates and prolong battery life

17-Sep-2020

Batteries fade as they age, slowly losing power and storage capacity. As in people, aging plays out differently from one battery to another, and it's next to impossible to measure or model all of the interacting mechanisms that contribute to decline. As a result, most of the systems used to ...
