Application

Ethylene sulfite (ES) is a sulfur analog of ethylene carbonate (EC), which can be used as an electrolytic additive for the formation of liquid electrolytes. These electrolytes are useful in the fabrication of lithium-ion batteries.

Ethylene sulfite is used as a film forming and high temperature additive for electrolytes in lithium ion batteries. It improves decomposition resistance of electrolyte.
