Unlocking the coupling mechanical-electrochemical behavior of lithium-ion battery upon dynamic mechanical loading

Dynamic mechanical loading, e.g. impact, is one of the major catastrophic factors that trigger short-circuit, thermal runaway, or even fire/explosion consequences of lithium-ion batteries (LIBs). In this study, the mechanical integrity and electrical coupling behaviors of lithium-ion pouch cells under dynamical loading were investigated. Two types of experiments, namely compression and drop-weight tests, are designed and conducted. The...
