Preparation of Li3V2(PO4)3/C Cathode Material Enhance Performance for Lithium Ion Batteries

Due to the high stability and potential characteristics to the economical and environmental, the Li₃V₂(PO₄)₃ increased the global concern on the polyanionic materials. In this work, we using Li₂CO₃, V₂O₅, NH4H2PO4 and PEG as raw materials to compared the flow phase reaction and high temperature solid state synthesis of lithium vanadium phosphate composites. The results of this study can be considered in making decision which conditions of achieved precipitation of carbon source can be efficiently applied in a real Electrochemical performance manufactory. The obtained results indicated that using Glucose as carbon source, and calcined at 800 ℃, 0.1C rate current conditions, high temperature solid state sintering of lithium vanadium phosphate composites for the first time following a discharge capacity of 119.31mAh/g, which has a good reusability performance.
