LiFePO4 material was synthesized at 650°C in an N2 atmosphere using a sol-gel method. This material showed a well developed XRD pattern (orthorhombic structure, Pnma) without peaks at 2θ=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%).

nanoMn3O4was prepared by a simple solvothermal method. The structure, morphology and electrochemical properties of the products were investigated by XRD, SEM and constant current discharge-charge test. The results of XRD and SEM shows that nanoMn3O4is high-purity, and it’s diameter is about 30 nm. It could deliver an initial discharge capacity of 1324.4 mAh g-1at the current density of 25.5 mA g-1, and the specific discharge capacity is 586.9 mAh g-1after 30 cycles at the current density of 30.4 mA g-1.

Plate-like LiMnPO4particles were prepared by polyol method. The chemical and physical properties of plate-like LiMnPO4particles were characterized by XRD and SEM. The thickness of plate-like LiMnPO4particles was approximately 35 nm. XRD pattern of plate-like LiMnPO4was good agreement with orthorhombic olivine structure. The first discharge capacity of C/LiMnPO4cathode was approximately 95 mAh/g. 99.9 % of initial discharge capacity was maintained after 100 cycles.
