Lithium iron phosphate (LFP) is an inorganic compound with the formula LiFePO₄. It is a gray, green, or black solid that is insoluble in water.

Lithium iron phosphate is used as a positive electrode material (cathode) of lithium iron phosphate batteries, a type of Li-ion battery. The negative electrode (anode) material for these batteries is typically graphite. This battery chemistry is used in power tools, electric vehicles, solar energy installations and more recently large grid-scale energy storage.

Lithium iron phosphate exists naturally in the form of the mineral triphylite, but as found naturally, this material has insufficient purity for use in batteries. Thus, battery-grade LFP powder must be synthesized.
