Analysis on the composition of lithium battery electrolyte

The composition of lithium battery electrolyteThe electrolyte is the four key materials of lithium batteries, called the blood of lithium batteries. And other advantages, what do we know about the composition of lithium battery electrolyte? The following author will analyze in detail the composition of lithium battery electrolyte and the types of lithium battery electrolyte. What is the composition of lithium battery electrolyte? Lithium battery electrolyte is mainly composed of three parts: (1) Solvent: cyclic carbonate (PC, EC); chain carbonate (DEC, DMC, EMC); carboxylate (MF) , MA, EA, MA, MP, etc.) (used to dissolve lithium salt). (2) Lithium: LiPF6, LiClO4, LiBF4, LiAsF6, etc. (3) Additives: film-forming additives, conductive additives, flame retardant additives, overcharge protection additives, additives for controlling the content of H2O and HF in the electrolyte, additives for improving low-temperature functions, and multifunctional additives. The electrolyte used in lithium batteries should generally meet the following basic requirements: A. The ion conductivity is high, generally 1x10-3~2x10-2S/cm. b. High thermochemical stability, no separation in a large voltage range. C. In a large voltage range, through a large electrochemical window, the stability of the electrochemical function is maintained. It has good compatibility with other parts of the battery, such as electrode material, electrode collector liquid and gap. Safe, non-toxic and non-polluting.
