摘要
LiFePO4 material was synthesized at 650 degrees C in an N-2 atmosphere using a sot-gel method. This material showed a well developed XRD pattern (orthorhombic structure, Pnma) without peaks at 2 theta-41 degrees, indicating the absence of FeP or metallic Fe2P impurities. The Li/LiFePO4 cell showed a high initial discharge capacity of more than 140mAh/g and no capacity decrease until the 50th cycle (>99.0%).
