Application

FEC is the main electrolyte additive in lithium ion batteriesLIB. FEC enables the formation of passive solid electrolyte interphase layer. With compact construction without increasing electrical impedance, that SEI film has better performance in LIB, which can significantly improve the performance of the electrolyte under low temperature.

Packaging and storage

This product is packed in stainless steel barrels with quick joint (N2 pressure: 0.11~0.13MPa ), with packing specification 200kg/200L, 100kg/100L or 25kg/25L. It should be stored in a cool, dry and draughty warehouse.
