Synthesis and characterization of LiFePO4 prepared by sol-gel technique
LiFePO4 material was synthesized at 650℃ in an N2 atmosphere using a sol-gel method.This material showed a well developed XRD pattern (orthorhombic structure,Pnma) without peaks at 20=41 °,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%).
