What should I do if the lithium battery expands due to heat? The reason for the expansion? How to fix it?

Lithium battery swells because the internal positive and negative chemical materials are short-circuited, super current, internal puncture short-circuit and other reasons, which cause rapid changes in internal chemical substances. The internal gas generates gas due to high temperature, and the battery is highly sealed. The product of this kind of gas cannot be discharged, only the expansion of the shell deforms, which has produced a larger space to store the gas.

The reason:

1. Overdischarge and overcharge of lithium battery;

2. Micro short circuit, that is, the diaphragm is damaged, which leads to partial contact between the positive and negative electrodes of the battery;

3. Continuous floating charge of lithium battery at high temperature causes side reactions of electrolyte and high rate charge and discharge at high temperature;

4. Charging at low temperature is actually a micro-short circuit caused by lithium piercing the diaphragm;

5. The aluminum plastic film of the outer packaging is corroded;

6. If the vacuum is not clean, or the mobile phone battery is used in a high altitude environment, the mobile phone batteries are all soft packaging, which has a great impact.

How to fix:

The lithium battery swells and is scrapped. For safety reasons, there is no need to repair it. It is recommended to hand over the battery to a recycling company for recycling.
