Abstract
Li0.97Er0.01FePO4/C composite was prepared by solid-state reaction, using particle modification with amorphous carbon from the decomposition of glucose and lattice doping with supervalent cation Er3+. All samples were characterized by X-ray diffraction, scanning electron microscopy, multi-point Brunauer Emmett and Teller methodes. The electrochemical tests show Li0.97Er0.01FePO4/C composite obtains the highest discharge specific capacity of 154 mAh g−1 at C/10 rate and the best rate capability. Its specific capacity reaches 131 mAh g−1 at 2C rate. Its capacity loss is only 14.9 % when the rate varies from C/10 to 2C.
