Lithium Iron Phosphate, LiFePO4 (LFP) Powder, 500g, 1.5um D50, Cathode Material

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. Most Li-ion used in consumer electronics products use other cathode materials, such as lithium cobalt oxide (LiCoO2) and lithium manganese oxide (LiMn2O4) and lithium nickel oxide (LiNiO2). The anodes are generally made of carbon, such as natural graphite and MCMB Mesocarbon Microbeads 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.
