Vinylene Carbonate (VC), CAS 872-36-6, is a colorless liquid with a boiling point of approximately 162°C. It is a highly polar compound with excellent solvency and is widely used in chemical and electrochemical applications.
In lithium-ion batteries, Vinylene Carbonate is a key electrolyte additive used to improve electrode/electrolyte interface stability. VC is electrochemically active and can decompose at relatively low potentials on lithium-based anodes, forming polymeric species that contribute to a stable solid electrolyte interphase (SEI).
Application in Lithium-Ion Batteries
VC is commonly incorporated into lithium-ion battery electrolytes together with carbonate solvents such as ethylene carbonate (EC) and propylene carbonate (PC). During the initial charging process, VC can preferentially decompose and contribute to SEI formation, helping reduce undesirable interfacial reactions and improve long-term battery stability.
For advanced battery applications, high-purity, battery-grade electrolyte components with carefully controlled water and acid levels are essential for consistent electrochemical performance.
