| 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. |
