Lithium iron phosphate battery refers to the ion battery with iron phosphate as the positive electrode material.

There are many kinds of cathode materials for lithium ion batteries, mainly potassium Burgundy, lithium manganese, lithium nickel, ternary materials, lithium iron phosphate and so on. Lithium cobaltate is the positive electrode material used by most lithium-ion batteries at present, while other positive electrode materials have not been mass-produced in the market due to a variety of reasons. Lithium iron phosphate is another type of ion battery. In terms of material principle, lithium iron phosphate is also an embedding/deembedding process, which is exactly the same as lithium cobalt and lithium manganate.

Lithium iron phosphate is gradually entering the Li-ion power battery market due to its advantages in safety, cycle life and material cost.
