Is abnormal leakage of the energy storage device a problem of the oil circuit

Why do Lib batteries go bad?

LiBs are sensitive to high power charging (fast charging), a too high or too low operating temperature, and mechanical abuse which eventually leads to capacity fade, short-circuiting, and the hazard of thermal runaway [3, 5, 6, 7, 8, 9]. Repeated fast charging can expedite battery aging, resulting in shorter battery life.

Did thermal runaway cause fire and explosion of lithium ion battery?

Why is overcharging a Lib a safety concern?

Generally, overcharging is considered the most severe safety concern, and it is usually caused by the malfunction of the charging control system, inappropriate design of BMS, and even the capacity inconsistency in the cells. Hence, developing the methods of efficiently controlling voltage plays a crucial role in resolving the safety issues of LiBs.
