Vinylene carbonate

Vinylene carbonate, also known as 1,3-dioxol-2-one or ethylene carbonate, is an organic compound with the chemical formula C3H2O3. It appears as a colorless transparent liquid and serves as a novel organic film-forming additive and overcharge protection additive for lithium-ion batteries. It can also be used as a monomer for the preparation of poly(vinylene carbonate).

It functions as a novel organic film-forming additive and overcharge protection additive for lithium-ion batteries, offering excellent high and low-temperature performance and anti-gas swelling properties. It helps enhance battery capacity and cycle life. Additionally, it can be used as a monomer for the preparation of poly(vinylene carbonate).
