Fluoroethylene Carbonate (FEC) (CAS: 114435-02-8)

This product, Fluoroethylene carbonate (FEC, CAS 114435-02-8), is developed as a key electrolyte additive for lithium-ion battery systems. As a fluorinated carbonate compound, it is widely used to improve the formation of a stable solid electrolyte interphase (SEI) on the anode surface, thereby enhancing cycle stability and overall electrochemical performance. Its high purity and controlled composition make it suitable for both experimental research and advanced energy material development. Available in multiple packaging sizes, FEC is valued for its role in enabling higher voltage and longer-lasting cells. This product is commonly applied in battery electrolyte formulation studies, materials science research, and the evaluation of next-generation lithium-based energy storage systems.
