摘要：The effect of pH concentrations on the size and morphology of FePO4&bullxH2O particles synthesized in a hydrothermal reactor was investigated in this work. FePO4&bullxH2O was prepared through co-precipitation by employing Fe(NO3)3&bull9H2Oand H3PO4 as raw materials. The LiFePO4 obtained through lithiation of FePO4&bullxH2O by using glucose as a reducing agent at 700°C. The electrochemical performance of LiFePO4 powder synthesized at 700°C were evaluated using coin cells by galvanostatic charge/discharge.The results indicated that the synthesized LiFePO4/C composites (pH=2) showed a superior electrochemical capacity of 146 mAh/g and possessed a capacity favorable cycling maintenance at the 0.1C rate and high electronic conductivity. © (2013) Trans Tech Publications, Switzerland.
