Effects of Sintering Temperatures on the Solid-Phase Synthesis of Lithium Vanadium Phosphate for Lithium-Ion Cathode Materials

Abstract:

Li3V2(PO4)3/C composite cathode material was prepared by carbothermal reduction using LiOHH2O, NH4H2PO4, NH4VO3 as raw material, sucrose as a coated carbon source, respectively. The electrochemical properties of Li3V2(PO4)3/C composite material prepared at different sintering temperature between 750°C and 900°C were investigated. The results demonstrated that by adjusting the sintering temperature, the electrochemical performance of the Li3V2(PO4)3/C material tends to be excellent, and when the temperature reaches 750°C, the Li3V2(PO4)3/C composite cathode material with the best electrochemical properties can be obtained.
