In　the　present　work,　nanocomposite　Li3V2(PO4)(3)/carbon　is　successfully　synthesized　by　combining　a　sol-gel　method　and　a　nanocasting　route,　and　then　it　is　characterized　by　means　of　X-ray　diffraction　(XRD),　thermogravimetric　analysis　(TG),　N-2　adsorption-desorption,　and　transmission　electron　microscopy　(TEM).　Furthermore,　this　nanocomposite　is　used　as　a　cathode　material　for　Li-ion　intercalation　and　exhibits　large　reversible　capacity,　high　rate　performance　and　excellent　long-term　cycling　stability.　For　instance,　a　large　reversible　capacity　of　95　mA　h　g(-1)　and　an　average　Coulombic　efficiency　of　99.1%　can　be　maintained　even　after　3000　cycles　at　a　high　rate　of　20C　in　the　potential　range　of　3.0-4.3　V.　Moreover,　the　Li3V2(PO4)(3)/C　nanocomposite　delivered　a　large　capacity　of　127　mA　h　g(-1)　at　a　high　rate　of　10C　in　the　voltage　range　of　3.0-4.8　V.　The　super　results　might　be　attributed　to　the　unique　hierarchical　architecture　of　the　Li3V2(PO4)(3)/carbon　nanocomposite.
