As a Lithium Battery Pack Supplier, let's analyze the cause of the explosion of a lithium battery:
1. Internal polarization is large;
2. The pole piece absorbs water and the echo drum is generated with the electrolyte;
3. The quality of the electrolyte itself, the performance title;
4. The amount of liquid injection during the injection time does not meet the process requirements;
5. The laser welding and welding sealing performance is poor in the process of the device, and the air leakage is measured.
6. Dust, extreme dust is easy to cause micro-short circuit, the cause of the cause is unknown;
7. The positive and negative electrode sheets are thicker than the process area, and it is difficult to enter the shell;
8. The title of the liquid injection seal, the bad performance of the steel ball seal leads to the air drum;
9. The shell material has a thick shell wall, and the shell deformation affects the thickness;
