Analysis of the important components and advantages of lithium battery electrolyte

Important components of lithium battery electrolyte The electrolyte is generally prepared from raw materials such as high-purity organic solvents, electrolyte lithium salts, and necessary additives under certain conditions and in a certain proportion. (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) Additives: film-forming additives, conductive additives, flame retardant additives, overcharge protection additives, additives to control the content of H2O and HF in the electrolyte, improve Low-temperature performance additives, multi-functional additives; advantages of lithium battery electrolyte The electrolyte used in lithium batteries is lithium perchlorate, lithium hexafluorophosphate and so on. As an important component of lithium batteries, electrolyte plays an irreplaceable purpose in improving the cycle performance and energy density of lithium batteries. It is a guarantee for lithium batteries to obtain the advantages of high voltage and high specific energy. The future direction of lithium battery electrolytes is very broad. . All in all, the future development trend of lithium battery electrolytes will be a gradual transition from the current organic liquid electrolyte to the solid electrolyte, during which various electrolytes of other systems will appear. The research and development of the electrolyte must not only comprehensively consider its electrochemical properties, thermodynamic properties, kinetic properties, etc., but also consider the compatibility of the corresponding positive and negative materials and the detailed use conditions of the battery for comprehensive design, so as to obtain each Comprehensive overall improvement of performance indicators. The improvement of the overall performance of lithium batteries is a comprehensive project that requires the coordinated progress of all components. The electrolyte plays the role of conducting electrons between the positive and negative electrodes of the lithium battery, which guarantees that the lithium battery obtains the advantages of high voltage and high specific energy. Lithium batteries are eco-friendly, so the future direction of this type of electrolyte is very broad. In general, the use of lithium battery electrolyte is very large, and its development prospects are also very broad.
