Introduction to lithium battery electrolyte

Lithium battery electrolyte is the carrier of ion transmission in the battery. Generally composed of lithium salt and organic solvent. The electrolyte is used to conduct ions between the positive and negative electrodes of the lithium battery, which guarantees that the lithium battery can obtain the advantages of high voltage and high specific energy. Electrolyte is generally prepared from raw materials such as high-purity organic solvents, electrolyte lithium salts, and necessary additives under certain conditions and in certain proportions. As the blood of the lithium battery, the electrolyte is responsible for the transportation of lithium ions. Its quality will directly affect the performance of the lithium battery and also affect the safety of the lithium battery to a certain extent. The electrolyte is an ionic conductor used for conduction between the positive and negative electrodes of a lithium battery. It is made up of raw materials such as electrolyte lithium salt, high-purity organic solvents and necessary additives in a certain proportion. Warm use, cycle life, safety performance and other aspects play a crucial role. The electrolyte is mainly composed of three parts: solvent: cyclic carbonate (PC, EC); chain carbonate (DEC, DMC, EMC); carboxylic acid esters (MF, MA, EA, MA, MP, etc.). Lithium salt: LiPF6, LiClO4, LiBF4, LiAsF6, etc. Additives: film-forming additives, conductive additives, flame retardant additives, overcharge protection additives, additives to control the content of H2O and HF in the electrolyte, additives to improve low-temperature performance, and multifunctional additives.
