Abstract. Thermal runaway is the main cause of lithium-ion battery accidents. Once a single battery occurs the thermal runaway, the whole battery pack will have the risk of explosion. Adding an insulating layer between the batteries and the module can reasonably and effectively inhibit the thermal runaway diffusion.
