Vinylene Carbonate (VC)

Vinylene Carbonate (VC) – SEI Film-Forming Additive for Li-ion Batteries

Vinylene Carbonate (VC) is a key electrolyte additive used in lithium-ion batteries to enhance SEI (Solid Electrolyte Interphase) formation on the anode surface. Even in small concentrations (typically 1–5%), VC significantly improves battery life, thermal stability, and cycle performance.
