China and South Korea are the leading exporters of fluoroethylene carbonate, accounting for the majority of global supply, while the United States, Germany, and Japan represent the largest importers, driven by demand from lithium-ion battery electrolyte manufacturers. Imports by the U.S. and EU member states have risen steadily since 2022, coinciding with increased production of advanced batteries and notable volatility in fluoroethylene carbonate prices amid tightening export controls and raw material constraints.
Fluoroethylene carbonate (FEC) is a colorless to pale yellow liquid at room temperature, with low volatility and a relatively high boiling point (~190–200 °C); it is typically odorless or exhibits a faint, characteristic ethereal odor. It is classified as a cyclic carbonate and a fluorinated organic compound, specifically a fluoro-substituted derivative of ethylene carbonate. FEC is primarily used as an electrolyte additive in lithium-ion batteries, where it enhances solid-electrolyte interphase (SEI) stability on graphite anodes and improves cycle life and safety performance. It serves as a key functional component—not a synthetic intermediate—in commercial battery electrolyte formulations for consumer electronics, electric vehicles, and energy storage systems.
