Fluoroethylene Carbonate CAS 114435-02-8

Fluoroethylene carbonate is a kind of chemical, the main Electrolyte Additive of lithium ion battery, the formation of SEI film performance is better, the formation of a tight structure layer but does not increase the impedance, can prevent the electrolyte further decomposition, improve the low temperature performance of the electrolyte.

Fluoroethylene Carbonate (FEC) is a high-purity, organic carbonate solvent often used in electrolyte solutions for lithium-ion batteries. It has a molecular weight of 156.03 g/mol and is recognized for its superior performance in enhancing the stability and safety of lithium-ion batteries. FEC plays a crucial role in the formation of solid electrolyte interface films on the anode, reducing gas generation and improving overall battery efficiency. This solvent is colorless, has a slight ether-like odor, and is typically stored and transported under controlled temperatures to maintain its quality and effectiveness.
