Methyl 2,2,2-Trifluoroethyl Carbonate (FEMC)
CAS 156783-95-8
Battery-grade fluorinated linear carbonate; solvent or co-solvent promoting a LiF-rich SEI on graphite and silicon anodes.
Battery Electrolyte Materials
Fluorinated linear carbonates and esters used as solvents, co-solvents and film-forming additives in lithium-ion, lithium-metal and silicon-anode electrolyte formulations.
Products
Bis(2,2,2-trifluoroethyl) Carbonate (TFEC)
CAS 1513-87-7
Additive for high-voltage cells; reduces electrolyte flammability and decomposes preferentially to a durable LiF-rich SEI.
2,2,2-Trifluoroethyl Acetate (TFEA)
CAS 406-95-1
Electrolyte component and trifluoroacetylation reagent; supports SEI formation and improves cycle life.
2,2-Difluoroethyl Acetate (DFEA)
CAS 1550-44-3
Fluorinated building block used in electrolyte development, API and agrochemical synthesis.
