| 1,The internal polarization is large. |
| 2,The pole piece absorbs water and reacts with the electrolyte, causing an air bulge. |
| 3,The quality and performance of the electrolyte itself. |
| 4,The liquid injection amount can not meet the process requirements. |
| 5,The laser welding sealing performance is poor in the installation process, and the gas leakage is detected. |
| 6,Pole dust is the most likely cause of micro short circuit. |
| 7, The positive and negative electrode plate is thicker than the process range, and it is difficult to enter the shell. |
| 8,Injection sealing problem, the sealing performance is not good, resulting in gas drum. |
| 9,The shell itself has a thick shell wall, and the deformation of the shell affects the thickness. |
| 10,The high temperature of the external environment is also the main cause of the explosion. |
