clear colorless to light yellow liquid

Vinylene carbonate (VC) can be used as an electrolytic additive for ionic liquid electrolyte for the formation of lithium-ion batteries. It can also be used in the formation of hybrid solid electrolyte interphase (SEI) for the fabrication of lithium-based batteries.

Vinylene carbonate is used as an additive to electrolyte solutions for anode side Lithium-ion batteries. It also acts as a sealant to seal at least a portion of the silicon-polyvinyl acid interface. It is further used for great improvement of high temperature performance of the battery.

Vinylene carbonate is produced by the known method by eliminating hydrogen chloride from chloroethylene glycol carbonate by means of tertiary amines, in particular triethylamine. Chloroethylene glycol carbonate is obtained by free radical chlorination of ethylene glycol carbonate by means of chlorine or sulphuryl chloride. This synthesis was published for the first time in 1953 by Newman and Addor (JACS, 1953, page 1263; JACS 1955, page 3789).

Nonflammable

Purify it by zone melting, or distillation, and stabilize it with 0.5% of 2,6-di-tert-butyl-p-cresol. [Beilstein 19 III/IV 1597, 19/4 V 72.]
