Abstract

The cathode is the most important component of a lithium-ion battery. The olivine structure lithium iron phosphate (LiFePO4) with its numerous appealing features, such as high theoretical capacity, acceptable operating voltage, increased safety, environmental benignity, and low cost, has attracted extensive interest as a potential cathode material for Li-ion batteries. As a precursor, FePO4 can be used to produce LiFePO4 on a large scale with high bulk density, discharge rate, and capacity. This can be realized by controlling the crystal size and morphology of FePO4. The characteristics, structure, and synthesis methods of FePO4 are discussed in this review. The relative merits of these synthetic methods, as well as some suggestions on how to improve them, are also presented.
