Battery explosion reasons

Battery explosion reasons
1, large internal polarization;
2, the pole pieces absorb water, react with the gas cylinder gas drum;
3, the quality of the electrolyte itself, performance issues;
4, Note liquid injection time not up to process requirements;
5, the assembly process of laser welding sealing performance is poor, leaking gas leak test;
6, dust, pole piece dust first lead to micro short circuit;
7, positive and negative films than the process of partial thick, hard shell;
8, liquid seal problem, the ball seal performance is not good lead to gas drum;
9, Shell incoming shell wall thickness, shell deformation affect the thickness;

10, the external environment is too high temperature is the main cause of the explosion.
