Causes of lithium battery explosion

As the application range of lithium batteries becomes wider and wider, explosions of lithium batteries occur from time to time. To ensure the safety of the battery system, the reasons for the battery explosion must be analyzed more carefully. The reasons for the explosion of lithium batteries are probably as follows:

1. The pole pieces of the internal lithium battery are highly polarized, causing an internal short circuit of the lithium battery to cause an explosion;

2. The pole piece of the lithium battery absorbs water and reacts with the electrolyte. The gas drum causes an internal short circuit of the lithium battery and causes an explosion;

3. The quality and performance of the electrolyte itself cause the internal short circuit of the lithium battery to cause an explosion;

4. The amount of liquid injected cannot meet the technological requirements when injecting liquid;

5. In the assembly process, laser welding has poor sealing performance, and air leakage when measuring air leakage;

6. Dust and pole piece dust are likely to cause micro short circuits first;

7. The positive and negative plates are thicker than the process range, making it difficult to enter the shell;

8. The problem of liquid injection sealing, poor sealing performance of the steel ball leads to air bulging;

9. The shell wall is too thick in the incoming shell material, and the shell deformation affects the thickness;

10. Explosion caused by external short circuit;

11. Excessive ambient temperature outside is also the main cause of explosion.
