Causes of lithium battery explosion

Time:Feb 01, 2023 Views:521


Cause

1. Internal polarization is large;

2. A polar slice absorbs water, reacts with the electrolyte;

3. The quality and performance of the electrolyte itself;

4. The amount of injection in injection does not meet the process requirements;

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

6. Dust and pole dust are prone to slight short circuits;

7. Positive and negative poles are thicker than the process range, and it is difficult to enter the shell;

8. Injecting liquid sealing problem, the performance of steel balls is not well sealed, leading to gas drums;

9. The shell has a thickness of the shell wall, and the deformation of the shell affects the thickness of the thickness;

10. Excessive environmental temperature is also the main cause of explosion.
