Research Progress in Li3V2(PO4)3 as Polyanion―type Cathode Materials for Lithium―ion Batteries

The polyanion―type cathode material of Li3V2(PO4)3 is an ideal cathode material for next―generation lithium―ion battery. It has attracted wide attention due to its comprehensive merits in high specific capacity, excellent structural stability, high operating―voltage, and low cost, etc. The structure, electrochemical properties, preparation methods, existing open questions and possible solutions of certain bottleneck issues of Li3V2(PO4)3 were discussed in detail in this paper. The research trends of Li3V2(PO4)3 cathode material was also prospected.
