Mechanical Properties of Real Aged Li-Ion Batteries

Description

Aged Li-ion pouch cells from a recent EV were subjected to a mechanical deformation. In comparison with respective fresh cells, they showed a more critical safety relevant behaviour-failure, and subsequent internal short-circuit at a lower deformation level and lower force. In order to identify the component that is mainly responsible for the altered cell behaviour, further coupon tests and microscopic analysis were carried out.
