Solid phase synthesis of High capacity LiFePO4 _-_Influence of starting materrials _-_

Abstract

LiFePO4 was synthesized by solid-state reaction method using various starting materials.LiFePO4 with higher capacity was obtained when FeC4H2O4 or FeC2O4:2H2O was used as a source of Fe because carbon might be dispersed well in LiFePO4 powder and suppress the formation of Fe3+ effectively.
