LiFePO4/C materials were synthesized by spray-drying method. The particle size of the LiFePO4/C was controlled by mechanical crushing or airflow crushing. The morphology, structure and electrochemical properties of the materials were characterized. The results show that: The smaller powder particle and better particle size distribution could be got using the two granularity control methods above. The special surface area of the material increased, the tap density decreased and the high rate performance deteriorated when the particle size of LiFePO4/C was controlled. After the particle size of LiFePO4/C is controlled the contacts of LiFePO4/C and carbon will deteriorate. The special capacity of the material decreases and the rate performance deteriorates, due to the stripping of carbon.

Enhanced high-rate performance of TiO2-B nanowires can be achieved by introducing “lattice voids” to produce a partially disordered structure. The obtained TiO2-B nanowires can show the same excellent rate capability as TiO2-B nanotubes, but a much higher volumetric capacity and better capacity retention.
