| 抄録(英) | In this work a comprehensive, experimentally validated, model is developed to simulate thermal runaway (TR) and venting in lithium-ion pouch cells, with NMC-based cathode, where TR is initiated by external heating. It is based on a coupled electrical-thermal previous model that included the initial energy input, the chemical decomposition processes of the anode, cathode and the electrical energy released by an internal short circuit and currently extended to include gas generation, internal pressure and venting dynamics. The model captures key features of TR, such as temperature evolution and temperature change rate, internal pressure changes and venting. Its findings are expected to support the foundation for future research dedicated on improving battery safety. 翻訳 |
