Due to the infinite relative volume variation of lithium metal anode, the solid electrolyte interphase(SEI) is very fragile and prone to rupture, which can lead to continuous damage/regeneration of the SEI, resulting in electrochemical inefficiency [22]. After continuous charge and discharge cycles, the growth of Li dendrite is emerging, which ...

Metallic lithium and electrolyte are unstable, and excessive metallic lithium deposition will cause the formation of dendrites to pierce the separator and cause battery short circuit. The most ideal solution at present is to develop anode materials with higher lithiation potential to reduce the risk of lithium deposition.
For battery packs, mechanical abuse can result in contact between high voltage components and conductive components, leading to a short circuit. For battery packs with liquid cooling systems, another possible cause is the cooling system rupture leading to the leakage of coolant, which may subsequently lead to a short circuit [29].
