Fluoroethylene carbonate 114435-02-8 is used as an electrolyte additive in Lithium ion batteries. It enables the formation of thin, smooth and stable passive solid electrolyte interphase (SEI) layer, which is insoluble in the electrolyte, in turn increasing the cycling efficiecny and discharge capacity retention of the secondary battery.
