Paper Title:
Synthesis of LiFePO4/C by Carbon Thermal Reduction Method and its Electrochemical Properties
  Abstract

LiFePO4/C were successfully synthesized by carbon thermal reduction method at sintering temperature of 650 °C for 12h, using Li2CO3, FePO4 and three organic carbon sources (citric acid, glucose and ascorbic acid) as starting materials. The crystal structure, morphology and electrochemical performances were characterized by X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM) and Charge/Discharge Test. The results showed that the sample using glucose as carbon source was shuttle type porous particles with bore diameter from 50 to 100 nm, charge/discharge test showed that the sample had not only high initial discharge capacity of 155.1mAh/g at 0.1C (17mA/g), and 144.8 mAh/g at 1C, but also excellent rate performance. Moreover, the capacities lose which was only 0.97% after 10 cycling number at 1C indicate its good cycling stability.
