摘要
LiFePO4 nanorods were facilely synthesized under hydrothermal condition. The crystalline structure and particle morphology of LiFePO4 powders were characterized by X-ray diffraction （XRD）, and field emission scanning electron microscopy （FE-SEM）. The electrochemical properties of LiFePO4/Li cells were investigated by galvanostatic test and cyclic voltammetry （CV）. The XRD result demonstrated LiFePO4 powder had an orthorhombic structure with a space group of Pnma. The synthesized LiFePO4 nanorods exhibited a first discharge capacity of 155 mAh·g-1 （91% of theorectical capacity） close to the theorectical capacity of LiFePO4 （170 mAh·g-1） at 0.1 C.
