Paper Title:
Electrochemical Properties of Carbon Doped LiFePO4 Cathode Materials Prepared by Spray Pyrolysis
  Abstract

Carbon doped LiFePO4 precursor particles were successfully prepared by spray pyrolysis. The saccharides such as monosaccharide and disaccharide or organic acid were used as carbon source. SEM observation showed that as-prepared particles had spherical morphology with narrow size distribution. XRD analysis revealed that olivine phase was obtained by heating at 700°C under the atmosphere of argon/hydrogen (5%). Electrochemical measurement revealed that the discharge capacity of LiFePO4 was improved by the addition of carbon. The addition of citric acid was most effective for the stabilization of cycle life.
