The reaction between the negative electrode of the lithium battery and the electrolyte.home solar energy storage lithium battery manufacture

release time:2023-04-22 Hits: Popular:AG11 battery

　　The carbon material of the lithium battery negative electrode is inevitable to react with the electrolyte during the first charge and discharge process of the battery. The impact on the lithium battery in this process:

　　1. Destroy the structure of the carbon negative electrode, the reaction of the occurrence will cause the structure of the carbon material to change

　　2. Protect the surface of carbon material, that is, forming a passivation film on the surface of the carbon negative pole or is called SOLID ELIDRECTRETE Interface (Solid Electrolyte Interface)

　　Three different reactions of electrolytes to negative carbon reaction changes

　　The solvent ion cross the electrode/electrolyte interface directly into the carbon material layer. The solvent molecules of the embedded layer restore the decomposition of lithium salt between the graphite layer under a lower potential, and at the same time generate a large amount of gases to cause the lithium ion with the lithium ionization of the solvent of the carbon material structure. This process is also generated by lithium salt and gas, but the generated lithium salt electrical medium will deposit on the carbon negative surface to form a passivation film to prevent the solvents from being embedded and restored.
