A novel hierarchical nano/microstructure of LiFePO4 microspheres consisting of nanofibers has been synthesized by a solvothermal approach with a mixture of water and 1,2-propanediol as solvent. The influences of temperature and solvent composition on the morphology and electrochemical performance of the products are investigated. The optimum temperature is 140 degrees C, and the optimum solvent composition is 1 : 5 for the volume ratio of water to 1,2-propanediol. The initial discharge capacity of the LiFePO4/C microsphere electrode is high and up to 163.9 mA h g(-1) and the capacity increased gradually to 164.9 mA h g(-1) after 10 cycles, indicating the excellent stability of the materials.
