Lithium battery explosion accidents occur frequently. Have you ever worried that this is a quality problem? In fact, in addition to the quality problems of lithium batteries themselves, improper user operation is also a major incentive. There are three main reasons for battery explosion: external short circuit, internal short circuit and overcharge.

External short circuit

External short circuit is mainly due to poor internal insulation design of battery pack, which leads to battery cell insulation failure, thus causing short circuit. In this case, the probability of battery explosion is not high.

Internal short circuit

The internal short circuit is caused by the burr of copper foil and aluminum foil piercing the diaphragm, or the crystallization of lithium atoms piercing the diaphragm. These tiny needle-like metals can cause micro-short circuits. In this case, the probability of battery explosion is very high.

Overcharge

The explosion caused by overshoot in use is also very common. For example, the explosion caused by the internal short circuit caused by the overcharge of the mobile phone does not necessarily occur when charging. The consumer's description is that he found the mobile phone very hot when he picked it up, and it exploded after throwing it away.

Matters needing attention

In order to reduce the explosion of lithium batteries, in addition to buying lithium batteries produced by regular manufacturers in regular stores, we should also pay more attention in our lives to prevent overshoot from causing explosions!
