Web8 okt. 2024 · Thermal runaway caused by external fire is one of the important safety issues of lithium-ion batteries. A fully coupled multi-region model is proposed to simulate the thermal response of lithium battery under fire conditions. The external fire is modelled by LES with an extended EDC combustion model. WebLithium Abstract Overcharge is a hazardous abuse condition that has dominant influences on cell performance and safety. This work, for the first time, comprehensively investigates the impact of different overcharge degrees on degradation and thermal runaway behavior of lithium-ion batteries.
