Analysis Of The Cause Of Lithium Battery​ Explosion

Analysis of the cause of lithium battery explosion

1, the internal polarization is larger

2, the pole piece absorbs water and reacts with the electrolyte

3, the quality of the electrolyte itself, performance issues

4, the amount of liquid injection does not meet the process requirements when injecting liquid

5, laser welding and welding sealing performance in the assembly process is poor, leaking, leak detection when leaking

6, dust, pole piece dust is easy to lead to micro short circuit

7. The positive and negative electrodes are thicker than the process range, and it is difficult to enter the shell.

8, the problem of liquid injection sealing, steel ball sealing performance is not good, resulting in air drum

9. The shell material has a thick shell wall and the shell deformation affects the thickness.
