Strain-rate dependence of the failure behavior of Lithium-Ion pouch cells under impact loading

A series of dynamic indentation tests over a velocity range of five orders of magnitude was conducted on Lithium-ion pouch cells with two different impactors. The strain-rate dependence of the failure development and fracture mode was analyzed by studying the cell's external response during the intrusion process and investigating postmortem internal fracture surfaces. A detailed force intrusion analysis is combined here for the first time with...
