When lithium ion battery is under abuse conditions such as short circuit, impact, overcharge, overheating, etc., a chain reaction that cannot be blocked easily occurs inside the battery, the battery temperature increases exponentially, and the battery experiences thermal runaway. During the process of battery thermal runaway, a large amount of smoke and intense jet fire often accompany. When the battery experiences thermal runaway, if not protected in time, the flame and thermal runaway process are easy to spread to the adjacent lithium ion energy storage unit, and then cause a larger scale fire and explosion accident.
