Bis(2,2,2-trifluoroethyl) carbonate (BTFC) is a fully fluorinated linear carbonate solvent engineered to enhance the electrochemical and thermal stability of lithium-based battery electrolytes. Its highly fluorinated structure facilitates the formation of a stable, LiF-rich interphase, which is critical for suppressing parasitic reactions, improving Coulombic efficiency, and enabling long-term cycling—especially in lithium-metal and high-voltage systems. BTFC also contributes to flame retardancy and lowers electrolyte flammability.
Battery-grade BTFC is an excellent choice for cutting-edge electrolyte systems requiring improved safety, wide electrochemical windows, and robust interfacial performance.
