Description

Fluoroethylene Carbonate (FEC)

RESEARCH GRADE MATERIAL

Product Introduction
Fluoroethylene Carbonate (FEC) is an important electrolyte additive for lithium-ion batteries, serving as a co-solvent. It facilitates the formation of electrolytes with high reversible capacity, enhances battery cycle efficiency and discharge capacity retention. Excels in improving battery performance (especially low-temperature performance) and is suitable for high-voltage systems. Its fluorine-containing structure enables the formation of a thin, stable Solid Electrolyte Interface (SEI) layer and provides excellent oxidation resistance. Widely used in battery material research.
