Case Study: Tianjin Institute of Power Sources achieves safer lithium-ion battery design with COMSOL Multiphysics

Tianjin Institute of Power Sources replaces hundreds of battery experiments with Comsol

The Tianjin Institute of Power Sources, a research institute in China, faced the challenge of analyzing fire hazards and safety in lithium-ion batteries for electric vehicles. Their researcher, Dr. Songrui Wang, needed to understand thermal runaway risks without relying solely on numerous dangerous and expensive physical experiments. They turned to vendor COMSOL, utilizing COMSOL Multiphysics software for simulation.

COMSOL provided a solution by enabling the creation of multiphysics models that simulate thermal behavior under adiabatic conditions, coupling heat transfer with electrochemical reactions. This approach implemented by COMSOL saved the institute and its partners significant money and time by reducing the need for physical testing. The results allowed for the optimization of cell geometry and material study, leading to a better understanding of battery safety aspects.
