摘要：
The preparation of vanadium-modified olivine LiFePO4 was attempted using vanadium-modified FePO4 precursor which was synthesized by controlled crystallization. The structure and electrochemical behavior of V-LiFePO4 with different vanadium contents were investigated. The electrochemical behavior of V-LiFePO4 materials at high rate and low temperature was compared with that of the LiFePO4 material. Incorporation of vanadium improved the electrochemical performance of LiFePO4. The investigation showed that the 3%V-modified LiFePO4 presented the best electrochemical performance.
