中文摘要	LiFePO/sub 4//carbon composite cathode material with the microstructure of nano-particles aggregated was prepared by granulating and subsequent pyrolysis process with carbon source of polyvinyl alcohol (PVA). The single LiFePO/sub 4/ phase and amorphous carbon could be found in the products. The influence of granulating process on the microstructure was significant. A special micro-morphology of optimum sample was observed. The capacity and cycle performance were studied at the charge and discharge rate of 0.1 C,0.2 C,0.5 C and 1 C. The optimum cathode sample (LFP/C4) has high reversible capacity and well cycle stability. Along with the increasing of cycle number, the capacity increases to its saturate value. After several cycles, the capacity is 149.9, 136.9, 123.2, 108.1 mAh middot g/sup -1/, respectively. Specially, at high 1 C rate, the cell reaches 63.6% of theory capacity to discharge capacity and has minor polarization effect with only 177 mV of potential difference ( Delta V) of charge-discharge median capacity.
