Interpretation of Simultaneous Mechanical-Electrical-Thermal Failure in a Lithium-Ion Battery Module

NREL's contributions to the U.S. Department of Energy's Computer-Aided Engineering of Batteries (CAEBAT) project largely focus on improving, validating, and incorporating mechanical-electrochemical-thermal (MECT) models into crush software tools. Abuse reaction/thermal runaway, internal short-circuit, and electrical/chemical/thermal network models are used by NREL researchers to evaluate battery safety issues at all scales. This video showcases NREL’s MECT models with the computer simulation of a lithium-ion battery experiencing mechanical-electrical-thermal failure.
