Will mobile phone batteries really explode? Under what circumstances will they explode?

Will mobile phone batteries really explode? Yes. The battery is responsible for storing electrical energy in the cell part, but when overcharged or overdischarged, it may break down the diaphragm in the inferior battery cell, short-circuit the cell, and cause high temperature and high pressure to explode. Therefore, the mobile phone battery is most likely to explode during the charging process. Under what circumstances will it explode? In addition to charging explosions, mobile phone batteries can also explode when they are not charged. The reason is that high voltage has been created when the mobile phone is charged before, and it has reached the critical point of the battery shell. When the external temperature and pressure exceed the critical point, an explosion will occur. To put it simply, there are three important reasons for the explosion of mobile phone batteries: 1. Battery quality Many mobile phone explosion accidents in China are mostly caused by fake original batteries. Industry veterans have revealed that these counterfeit original batteries are all recycled and refurbished old batteries. Excessive raw material impurities, unqualified workmanship, and inadequate battery safety protection design will cause battery explosion. 2. The battery cell is overcharged for a long time. Under the long-term charging state, overcharge and overcurrent will also cause high temperature and high pressure, which may cause hidden danger. Lithium-ion batteries may instantaneously discharge under special conditions such as temperature, humidity, and poor contact, resulting in a large amount of current, spontaneous combustion or explosion. 3. Battery short circuit When the mobile phone is in a high temperature state, or is subject to impact, metal friction, etc., it may cause the battery to short circuit and explode.
