Analysis of the Causes of Lithium Battery Explosion.18650 lithium rechargeable battery

release time:2023-09-08 Hits:     Popular:AG11 battery

  

  1. Large internal polarization;

  2. The electrode absorbs water and reacts with the electrolyte, causing a gas bubble;

  3. The quality and performance issues of the electrolyte itself;

  4. The amount of liquid injected cannot meet the process requirements;

  5. Poor sealing performance of laser welding during the assembly process, resulting in air leakage during leak detection;

  6. Dust and polar dust can first cause micro short circuits;

  7. The positive and negative electrode plates are thicker than the process range, making it difficult to insert into the shell;

  8. Liquid injection sealing problem, poor sealing performance of steel balls leading to air bubbles;

  9. The incoming material of the shell has a thick shell wall, and the deformation of the shell affects the thickness;

  10. The high temperature outside is also the main cause of the explosion.
