8 major reasons for the explosion of lithium batteries

Lithium battery manufacturers: There are too many accidents in the explosion of lithium batteries in life, such as Samsung mobile phone battery explosion, wholesale mobile battery manufacturers explain the eight reasons for the explosion of lithium batteries

1. The internal poles of the lithium battery vary greatly, causing the explosion of the lithium battery;

2. The rechargeable lithium battery pole piece absorbs water and reacts with the electrolyte swell, which will also cause the lithium battery to explode.

3. The quality and performance of the rechargeable lithium battery electrolyte itself.

4. When the manufacturer injects liquid into the lithium battery, the amount of liquid injection does not meet the process requirements, resulting in a safety hazard of the lithium battery.

5. The problem of sealing after filling the lithium battery has not reached the standard, resulting in poor sealing performance and battery swell.

6. In the assembly process, the laser welding sealing performance is poor, leakage.

7. The cause of the explosion is dust, and the extreme dust is easy to cause micro short circuit.

8. The positive and negative electrodes of lithium battery are thick.

The 8 major reasons for the explosion of lithium batteries should be noted in the following 6 points:

1, external short circuit

2, internal short circuit

3, overcharge

4, over discharge

5, the water content is too high

6, the negative capacity is insufficient
