1. Large internal polarization!
2. The electrode piece absorbs water and reacts with the electrolyte to form an air drum.
3. The quality and performance of electrolyte itself.
4. The liquid injection volume can not meet the process requirements.
5. In the assembly process, the sealing performance of laser welding is poor, and the gas leakage and gas leakage measurement are missed.
6. Dust and electrode dust are easy to cause micro short circuit at first, and the specific reason is unknown.
7. The positive and negative electrode sheets are thicker than the process range, and it is difficult to enter the shell.
8. The sealing problem of the liquid injection and the poor sealing performance of the steel ball lead to air drum.
9. The shell wall of the incoming shell is too thick, and the shell deformation affects the thickness.
