What is Vinylene Carbonate？

Vinylene Carbonate is a cyclic carbonate ester appearing as a colorless to pale yellow transparent liquid. It is soluble in most organic solvents including acetone, acetonitrile, and dimethyl carbonate, but reacts with water. The compound contains a highly reactive carbon-carbon double bond conjugated with a carbonate group, making it a valuable electrolyte additive for lithium-ion batteries to form stable solid electrolyte interphase (SEI) films.

Safety Profile:

Vinylene Carbonate is flammable and causes severe skin burns and eye damage. May cause respiratory irritation. Use appropriate personal protective equipment including chemical-resistant gloves, face shield, and adequate ventilation when handling. Avoid contact with skin and eyes. The substance is toxic to aquatic life. For comprehensive safety information, always consult the full Safety Data Sheet (SDS).

Storage Requirements:

Store in a cool, dry, well-ventilated area under inert atmosphere (argon or nitrogen). Keep containers tightly closed and sealed. Maintain storage temperature between 2-8°C. Keep away from moisture, heat, and open flames. Handle under dry inert gas when opening containers.

Transport & Packaging:

Vinylene Carbonate is packaged in glass bottles or HDPE plastic bottles (1 kg or 5 kg net weight per bottle) under inert gas atmosphere, placed in sturdy outer containers. Transport as flammable liquid and corrosive material according to applicable regulations. Ensure containers are properly sealed and protected from physical damage during transportation. Store away from incompatible materials.
