Trifluoroethyl Methyl Carbonate (FEMC) (CAS: 156783-95-8)

This product, trifluoroethyl methyl carbonate (FEMC, CAS 156783-95-8), is a fluorinated carbonate compound developed for advanced energy storage applications, particularly in lithium-ion battery electrolytes. Its molecular structure combines a trifluoroethyl group with a methyl carbonate moiety, which imparts high oxidative stability, low viscosity, and enhanced compatibility with high-voltage cathode materials. As a functional solvent or additive, FEMC helps improve cycling performance, safety, and electrochemical stability of electrolyte systems. It is commonly used in research laboratories and pilot-scale development targeting next-generation battery chemistries, including high-energy-density lithium metal and lithium-ion cells. Available in a range of batch sizes from 20 g to 1 kg, the material is suitable for both small-scale optimization and extended experimental studies, supporting reproducible results in electrolyte formulation and material characterization.
