AGV balance car 12V55AHOPZS tubular battery capacity calculation method3 lithium negative modification






Peled in 1979, the concept of SEI film was first proposed. The multi-phase chemical structure of the SEI membrane had a direct impact on electroplating, peeling behavior and cycle life of metal lithium batteries. It is an important aspect of solving the challenge of metal lithium secondary battery.


According to the current research, the modified idea of ​​the Lithium negative electrode by modifying the SEI film is mainly: (1) The main component of the SEI film is made of decomposing reaction product of negative electrode lithium and electrolyte, and modified the SEI film by improving the electrolyte. Yes * Direct and efficient method; (2) artificial non-in-situ forms a layer of SEI film in lithium negative surface, more flexible, and the plan is more simple and economical.






3.1 Modified SEI film by electrolyte in situ


Typically, the lithium battery electrolyte is mainly composed of an organic solvent, a lithium salt, and an additive, and almost all of the electrolyte components have an important effect on the formation of the SEI film, and the stable SEI film is formed directly by improving the component of the electrolyte. Direct efficiency.
