Uses：Vinyl carbonate is a new type of film forming additive and overcharge protection additive for lithium- ion batteries. It can form solid electrolyte interface film (SEI film) by electrochemical reaction on the negative electrode surface during the initial charge and discharge of lithium-ion batteries, and effectively inhibit the embedding of solvent molecules. Vinyl carbonate has good performance at high and low temperature and excellent anti-bloating function, which can improve the capacity and cycle life of the lithium-ion battery. In addition, Vinyl carbonate can also be used as a monomer for the preparation of polyvinyl carbonate.

Storage：This product should be stored in a cool, dry and ventilated place. Keep away from heat and fire source. Avoid direct light irradiation. Avoid contact with oxide, reducing agent, acids and bases.
