LiFePO4 is expected as the promising cathode materials for lithium-ion batteries. Chemical precipitation is an ideal method to prepare LiFePO4. From the point of view of two kinds of precursor synthesis routes, overseas and domestic research advances of LiFePO4 prepared by chemical precipitation are summarized, in which metal ion doping and carbon coating are usual modification methods. The existing problems in researches and future research directions are discussed and prospected, which provides references for researches of LiFePO4 cathode materials.
