Positive Electrode Material

Positive-electrode material LiFePO4/C was prepared using FePO4•2H2O as raw material via a rheological phase method. Orthogonal experiment was designed to systematically investigate the effects of the ratio of raw materials, calcining temperature and holding time on the morphology and electrochemical performance of LiFePO4/C. The results showed that the optimal parameters were as follows: synthesis temperature 650 °C, time 10 h. The sample prepared with optimal parameters showed discharge capacities of 147.5 mAh•g-1 at 0.2 C and 133.7 mAh•g-1 at 1 C rate, with good cycle performance.
