Methyl trifluoroethyl carbonate (FEMC), also known as fluoroethane methyl carbonate and (2,2,2-trifluoroethyl) methyl carbonate, has a molecular formula of C4H5F3O3 and is a chemical substance. FEMC appears as a colorless liquid and has the advantages of good chemical stability, good flame retardancy, high voltage resistance, good film-forming properties, and low viscosity. As a fluorinated additive for electrolytes, it has broad application prospects in the field of lithium-ion batteries.

In recent years, fluorinated additives have been used as functional electrolyte additives, and the industry’s prosperity has continued to increase. The fluorine atoms in fluorinated additives replace hydrogen, which can effectively increase the oxidation potential and reduction potential of the electrolyte, thereby improving battery cycle performance. ETFEC, MFA, ETFA, FEMC, etc. are representative products of fluorinated additives. As the application demand for fluorinated additives grows, the development speed of the FEMC industry will further accelerate.

According to the “2023-2028 China Methyl Trifluoroethyl Carbonate (FEMC) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center >》shows that lithium-ion batteries are the largest demand side of FEMC. Benefiting from the accelerated development of the new energy automobile industry, the market demand for power batteries is increasingly strong, and lithium-ion batteries are the representative product of power batteries. According to statistics from the Ministry of Industry and Information Technology, my country’s lithium-ion battery production will reach 750GWh in 2022, a year-on-year increase of more than 130%. As a fluorinated additive for electrolytes, FEMC has broad application prospects in lithium-ion battery electrolyte systems. As downstream demand grows, the industry development space will continue to expand.

FEMC can effectively improve the high-voltage stability of lithium-ion battery electrolyte, but its redox stability is poor. In recent years, attracted by market prospects, global enthusiasm for FEMC research and development has continued to rise. In November 2021, the KhalilAmine team at Argonne National Laboratory in the United States added fluoroethylene carbonate (FEC) to the electrolyte containing FEMC and DFEC, and successfully produced high-voltage lithium ions with good redox stability and good cycle stability. Battery electrolyte. In the future, with in-depth research and technological advancement, high performance will become the mainstream development trend of the FEMC industry.

The main players in my country’s FEMC market include Shandong Shida Shenghua Chemical Group Co., Ltd., Wuhan Kmic Biomedical Technology Co., Ltd., Hubei Jiufenglong Chemical Co., Ltd., Hubei Shineng Chemical Technology Co., Ltd., Hubei Shuangyan Chemical Co., Ltd., etc. Shi Dasheng Huawei is my country’s leading FEMC company, focusing on the research, development, production and sales of lithium-ion battery electrolytes. Currently, Shi Dashenghua is promoting a FEMC production project with an annual output of 2,000 tons.

Industry analysts said that FEMC has the advantages of high voltage resistance and good film forming properties, and is in strong demand in the field of lithium-ion batteries. The pace of development continues to accelerate. In recent years, with in-depth research and technological advancement, the market share of high-performance FEMC has continued to increase. At present, my country’s FEMC market is dominated by small and medium-sized enterprises, and the industry concentration is low. In the future, companies with high-performance FEMC large-scale production capabilities are expected to occupy more market shares.
