摘要

Abstract

LiFePO4/C composite cathode materials were synthesized using modified liquid precipitation and solid-state reaction in order to improve the electrochemical performance of LiFePO4 and suitable for low-cost industrial production.The crystalline structures

morphology of particles were characterized by X-ray diffraction (XRD)

scanning electron microscopy (SEM) etc.The results showed that modified liquid precipitation particles were 100nm

meanwhile

having good crystallinity .Compared with the latter，the former has higher discharge specific capacity and excellent cycle performance

whose highest discharge specific capacity was 167.91 mA·h·g-1 at 0.47C under room temperature，even at 1.0C， LiFePO4/C also had high discharge specific capacity

which was 155.71 mA·h·g-1.After 30 times cycling

the discharge specific capacity were 166.42 mA·h·g-1 and 153.81 mA· Key words: 液相沉淀法
