What are the components of lithium battery electrolyte?

Lithium battery electrolyte composition (1) Solvent: cyclic carbonate (PC, EC); chain carbonate (DEC, DMC, EMC); carboxylic acid esters (MF, MA, EA, MA, MP, etc.); (Used to dissolve lithium salt) (2) Lithium salt: LiPF6, LiClO4, LiBF4, LiAsF6, etc.; (3) New additives: film forming additives, conductive additives, flame retardant additives, overcharge protection Additives, new additives to control the content of H2O and HF in the electrolyte, new additives to improve low temperature function, multifunctional additives. Solvent analysis commonly used in lithium battery electrolyte Carbonate: Ethylene carbonate (EC) is an organic solvent with excellent functions that can dissolve a variety of polymers. It irritates the eyes, affects the respiratory system and damages the skin. This product should be stored in a cool, ventilated, dry place, and stored and transported in accordance with general chemical regulations. Carboxylic acid esters: There are many types, the cost is also relatively cheap, and the purity is simple to achieve. The chemical properties are fairly stable, that is, it is not very simple to be oxidized (except formate), and it is not very simple to be reduced, and it is mostly liquid at room temperature. Carbonate and carboxylate: The mixed solvent of the two can make the lithium battery pack have a high potential for forming the SEI film on the negative electrode during the first charging process, prevent solvent reduction, ensure battery safety, and improve the capacity retention rate of low-temperature batteries. Rate charge and discharge capacity. Disclaimer: Some pictures and content of the articles published on this site are from the Internet. If there is any infringement, please contact to delete it.
