Abstract

Lithium iron phosphate(LiFePO4)has received particular interest as cathode materials for large-size lithium-ion batteries in electric vehicles application. The preparation process of LiFePO4 varies with starting materials. This paper reviews the research progress in various synthetic routes for LiFePO4 developed by Shanghai Jiao Tong University with focus on the preparation process of LiFePO4/C and its charge-discharge performance. Approaches to improve the performance of LiFePO4/C cathode in different working temperature range are also presented. Finally,the process engineering problems of LiFePO4/C cathode material preparation are discussed,including the effects of reductant,carbon source and process equipment.
