[PDF Version]Starting from the external strain mechanism of the lithium battery, the strain change of the lithium battery explosion proof valve under normal conditions and overcharge is studied. Based on the comparison of the two conditions, an online warning scheme using sliding window and data standard deviation is proposed.
Despite some progress in current research on the TR explosion of lithium-ion cells, little attention has been given to the TR explosion characteristics of cells after charging and discharging at different capacity rates (C-rates), especially in confined spaces.
Gas generation of Lithium-ion batteries (LIB) during the process of thermal runaway (TR), is the key factor that causes battery fire and explosion.
Consequently, some scholars have begun to study the in-situ explosion characteristics of lithium-ion cells during TR, exploring the effects of cell materials, SOC, ventilation conditions, heating power, and other factors in both open and confined spaces.
The main reason for this is the spontaneous combustion accident caused by the thermal runaway of the battery. According to the characteristics of LIBs, new energy vehicles can ignite very quickly, almost instantaneously, or even explode [ 8, 9, 10 ].
Their findings demonstrated that under overcharge conditions, battery combustion is more severe, leading to higher fire risks. Experimental studies on the thermal runaway (TR) of lithium-ion batteries have shown low repeatability and involve certain risks, requiring significant human and material resources.
