Application

1. Used as Li-ion battery electrolyte additive. Ethylene sulfite is an excellent membrane formation additive, which is capable of preventing propylene carbonate from intercalating to graphite and remarkably extending cycle life of Li-ion batteries whose anodes are made of modified natural graphite.

2. Used as pharmaceutical intermediate as well as intermediate in organic synthesis.
