hospho-olivine LiFePO has been prepared using a facile hydrothermal method by optimizing the reaction temperatures. Structural and morphological properties of the as-prepared LiFePO powders are systematically characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), infrared spectra, UV-vis spectra, and Mossbauer spectroscopy. It is demonstrated that the samples prepared in the temperature range from 160 to 200 ℃ crystallize in a single phase of phospho-olivine structure. All particles are rod-like,showing dimensions of approximately 150~200 nm in width and 500~600 nm in length with apreferential growth direction of [001]. Within the lattice of LiFePO rods, Fe sites, which increases the cell volume. The electrochemical performance of LiFePO is investigated by charge/discharge experiments.It is found that LiFePO rods prepared at 200 ℃ deliver a specific discharge capacity of 147 mAh g disorderly occupying the Li
