Coupled Mechanical–Electrochemical–Thermal Study on the Short-Circuit Mechanism of Lithium-Ion Batteries under Mechanical Abuse

The mechanical–electrochemical–thermal coupled failure behavior of lithium-ion batteries under external mechanical crushing has attracted a great deal of attention due to its complicated mechanism and significant safety risk. In this study, a simultaneously coupled modeling methodology incorporating mechanical, electrochemical, short-circuit, and thermal modeling is proposed for predicting the short-circuit behavior of a pouch battery under...
