Abstract

Olivine $LiFePO_4$ cathode materials were synthesized by hydrothermal reaction, and coated by carbon black. The powders were characterized by the X-ray diffraction. $LiFePO_4$/Li cells were characterized electrochemically by charge/discharge experiments and ac impedance spectroscopy. The result showed the discharge capacity of $LiFePO_4$/Li cell was 133 mAh/g at the first cycle, and 128 mAh/g at the 30th cycle, respectively.
