The electrolyte solvent is closely related to the comprehensive performance of the battery.The commonly used electrolyte solvents and their physical properties in China are introduced,among which di-methyl carbonate and methyl ethyl carbonate have the highest usage.At the same time,the current produc-tion technology of dimethyl carbonate and methyl ethyl carbonate is mainly introduced,and the advantages and disadvantages of the production process of dimethyl carbonate are compared.The mainstream process for synthesizing dimethyl carbonate by ester exchange method is also discussed.Finally,the production ca-pacity and market situation of the two main electrolyte solvents are analyzed,and the direction for future in-dustrial development is proposed.
