HYDROTHERMAL SYNTHESIS OF LITHIUM IRON PHOSPHATE CATHODES AND ITS ELECTROCHEMICAL PERFORMANCE

Liu Ling

ABSTRACT: LiFePO4 powders were prepared via hydrothermal synthesis. The effects of synthesis conditions on structure and electrochemical behavior of LiFePO4 were studied. The samples were characterized by X-ray Diffraction, Scanning Electron Microscope (SEM) and charge-discharge test. The study showed that LiFePO4 had an ordered layered structure and good electrochemical properties. The results showed that the performance of the powder was affected by the stoichiometric of the reactants and the synthesis parameters.
