Description

technical field [0001] The invention relates to the technical field of electrolyte suitable for lithium ion batteries, in particular to a preparation method of methyl trifluoroethyl carbonate. Background technique [0002] Methyl trifluoroethyl carbonate can be used as a co-solvent or additive in lithium-ion battery electrolytes. [0003] Lithium-ion batteries have the advantages of high energy density, high output voltage, long cycle life, no memory effect, and less environmental pollution. They are the most attractive and potential secondary batteries. At present, the solvents used in lithium-ion battery electrolytes are usually carbonates, which can improve the charge-discharge capacity and cycle life of lithium-ion batteries, but their flash point is low. In recent years, fires caused by lithium-ion batteries There are even reports of explosions. The safety of lithium-ion batteries has been widely concerned by people, and safety is also the bottleneck restricting the d...
