Abstract

The carbon coating Li3V2(PO4)3 powder samples were synthesized by carbon incorporation solid state reaction.The structure,morphology and electrochemical properties have been studied by X-ray powder diffraction,scanning electron microscopy and automatic battery tester system,respectively.Carbon coating on Li3V2(PO4)3 would prevent the particles from agglomerating,reduce the particle size,raise the conductivity and improve the samples′ electrochemical performance.

Key words： Li3V2(PO4)3; carbon coating; conductivity; electrochemical performance
