Lithium iron phosphate (LFP)

1kg, powder form.

CAS Number: 15365-14-7

Lithium iron phosphate (LiFePO₄), also known as LFP, is a cathode material used in lithium ion (Li-ion) batteries. Its primary applications are electric vehicles (EV) and distributed energy storage. The anodes are generally made of carbon, such as natural graphite and  mesocarbon microbeads(MCMB)synthetic graphite

LFP powder is coated by carbon for use in lithium ion batteries as the cathode material. Carbon-coated lithium iron phosphate (C-LiFePO₄) powders have been produced at the commercial scale by a controlled solid-state reaction method.
