Hydrothermal Synthesis of LiFePO4 Cathode

Hydrothermal synthesis of LiFePO4 cathode is reviewed on the basis of problems hampering the application of LiFePO4, which involves purity, morphology and conductivity. The cost of raw materials and synthetic route are considerd, and a possible way in mass production of LiFePO4 is proposed. Although the article focuses on hydrothermal synthesis of LiFePO4, but other low-temperature synthesis processes, including solvothermal, supercritical, polyol and ionothermal, are also discussed in the related sections. Finally, advantages and disadvantages of hydrothermal synthesis of LiFePO4 cathode are compared with other synthesis processes, with the focuses on the difficulty in mass production of LiFePO4, and the means to solve the problem is presented.
