Effects of electrolyte, thickness, and casing stiffness on the dynamic response of lithium-ion battery cells

The dynamic response of lithium-ion cells under mechanical loading is known to feature significant strain-rate effects. Opposite trends in failure strength have been observed between elliptic cells (with hard shell casing) versus pouch cells, when cells were subjected to high-speed loads. This paper elucidates the reason for the observed effects by comparing dynamic data from tests on lithium-ion cells in different configurations. It reports on...
