Abstract:

This paper focuses on the safety research of traction batteries under mechanical abuse. The failure mechanism of Li-ion batteries under mechanical abuse, such as indentation, nail penetration and compression, are summarized and analyzed, and a variety of analysis models currently used for the simulation on battery mechanical abuse are reviewed in detail. Finally, an outlook of future researches on the failure mechanism, the simulation models and the safety design of battery mechanical abuse are given.

Key words: lithium-ion battery, mechanical abuse, failure mechanism, simulation model
