Under what circumstances, the mobile phone battery will explode?

There are three important reasons for the explosion of mobile phone batteries: (1) Battery quality Actually, battery explosions currently occur, and many are caused by the use of non-original batteries. Inferior batteries sold by unscrupulous merchants counterfeit as original batteries may explode due to excessive raw material impurities, unqualified manufacturing processes, and inaccurate battery safety protection related designs. (2) If the battery is overcharged for a long time, overcharge or excessive current may lead to high temperature and high pressure, and the safety of the battery is buried. Lithium-ion batteries may cause excessive instantaneous current under special temperature, humidity, and poor contact conditions, and the battery may explode or ignite spontaneously. (3) Battery short circuit When the battery is in a high temperature state, or subjected to impact or metal friction, it may cause an electric short circuit and explode.
