Lithium iron phosphate or lithium ferro-phosphate (LFP) is an inorganic compound with the formula LiFePO
₄. It is a gray, red-grey, brown or black solid that is insoluble in water. The material has attracted attention as a component of lithium iron phosphate batteries,^[1] a type of Li-ion battery. This battery chemistry is targeted for use in power tools, electric vehicles, solar energy installations^[2] and more recently large grid-scale energy storage.^[3]

Most lithium batteries (Li-ion) used in consumer electronics products use cathodes made of lithium compounds such as lithium cobalt oxide (LiCoO
₂), lithium manganese oxide (LiMn
₂O
₄), and lithium nickel oxide (LiNiO
₂). The anodes are generally made of graphite.

Lithium iron phosphate exists naturally in the form of the mineral triphylite, but this material has insufficient purity for use in batteries.
