General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

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.
