Description

TFEC (Trifluoroethyl Chloroformate) | Boost Cycle Life & Stability

        Extended Cycle Life: Significantly reduces capacity fade by protecting the cathode from degradation during long-term cycling.

  • Enhanced High-Voltage Stability: Enables stable operation of batteries at higher voltages (e.g., >4.4V), unlocking greater energy density.

  • Improved Thermal Safety: Contributes to a more thermally stable battery system, a critical factor for safety.

  • Superior Cathode Protection: Forms a thin, uniform, and protective CEI (Cathode Electrolyte Interphase) on sensitive materials like Lithium Cobalt Oxide (LCO) and Nickel Manganese Cobalt (NMC).

  • Compatibility: Effective in carbonate-based electrolytes and compatible with silicon-anode systems.
