摘要：
Nanosized C-LiFePO4 particles are synthesized by a microwave-assisted solid-state method. A novel conductive agent, Ag/C nanocables, is adopted for the first time to modify C-LiFePO4 so as to improve the electronic conductivity. The as-synthesized samples are characterized by powder X-ray diffraction and transmission electron microscopy to determine the microstructure and morphology. Electrochemical techniques are used to investigate the electrochemistry performance of the samples. The results indicate that the rate capacity of the Ag/C nanocables-modified C-LiFePO4 is improved due to the nanosized particle distribution and enhanced electronic conductivity.
