The lithium battery electrolyte additive industry is developing rapidly and the market demand for fluoroethylene carbonate (FEC) continues to rise.

Fluoroethylene carbonate (FEC), also known as 4-fluoro-1,3-dioxolane-2-one, has a chemical formula of C3H3FO3 and is a chemical substance. Fluoroethylene carbonate appears as a colorless and transparent liquid. In its pure material state, its chemical properties are stable. It is mainly used to prepare lithium battery electrolyte additives, which can improve battery cycle life and capacity.

The synthesis methods of fluoroethylene carbonate include halogen exchange method and direct fluorination method. The halogen exchange method is the mainstream synthesis method of fluorinated ethylene carbonate, and can be subdivided into organic base catalyst method, solid dispersion method, phase transfer catalyst method, etc. The phase transfer catalyst method usually uses chlorinated ethylene carbonate, fluorinating agent and organic solvent as raw materials. A phase transfer catalyst is added to increase the solubility of alkali metal fluoride in non-polar organic solvents, further improve the reaction rate, and finally produce Fluoroethylene carbonate.

According to the “2022-2027 Fluoroethylene Carbonate Industry In-depth Market Research and Investment Strategy Suggestions Report released by the Industrial Research Center , there is a correlation between the development of the fluoroethylene carbonate industry and the shipment volume of lithium battery electrolyte additives. my country’s electrolyte industry started late and initially relied entirely on imports. Driven by technological innovation and market demand, my country’s electrolyte has gradually realized import substitution, and the industry has ushered in a stage of rapid development. In 2021, my country’s lithium battery electrolyte additive shipments reached 35,000 tons, a year-on-year increase of 75.8%. Fluoroethylene carbonate is widely used as an electrolyte additive in the production process of lithium batteries, accounting for nearly 40.0% of my country’s electrolyte additive market.

Fluorinated ethylene carbonate is a fluorine-containing additive that is currently widely used, with strong demand in the fields of new energy vehicles, medicine, pesticides, chemicals, etc. The SEI film produced by fluorinated ethylene carbonate contains more lithium fluoride components, which can significantly improve the performance of lithium batteries, especially the cycle stability of silicon-based lithium batteries. In recent years, with the rapid economic development and the deepening of environmental protection concepts, the purchase of new energy vehicles in my country has increased significantly, driving the continued increase in lithium battery shipments. Fluoroethylene carbonate, as a segmented product of lithium battery electrolyte additives, has an increasingly strong market demand.

Rongcheng Qingmu High-tech Materials, Yongtai Technology, Suzhou Huayi New Energy, Jiangsu Huasheng Lithium Battery, Zhangjiagang Hankang Chemical, etc. are the main manufacturers of fluorinated ethylene carbonate in my country. Huasheng Lithium Battery focuses on the production and sales of lithium battery electrolyte additives. In 2021, the company’s fluorinated ethylene carbonate sales volume reached 2,000 tons, ranking first in the industry.

Industry analysts said that fluorinated ethylene carbonate is in strong demand in the field of lithium battery electrolyte additives. Driven by technological innovation, the industry The development prospects will continue to improve. At present, my country’s fluoroethylene carbonate industry is highly concentrated, with leading companies occupying a dominant position in the market. With the rapid development of downstream industries such as new energy vehicles, my country’s fluoroethylene carbonate market will continue to expand.
