Nanostructured Li3V2(PO4)3 /carbon composite (Li3V2(PO4)3/C) is successfully prepared by incorporating precursor solution into expanded pore structure of highly mesoporous carbon. XRD, SEM and TEM are used to characterize the composite structure. The particles sizes of the samples are centered at ~ 20 nm and well dispersed in the carbon matrix. When cycled in a voltage range of 3-4.3 V, Li3V2(PO4)3/C cathode delivers a reversible capacity of 122 mAh g-1 at 1C-rate and maintains a specific discharge capacity of 83 mAh g-1 even at 32 C-rate. Therefore, nanostructured Li3V2(PO4)3 and mesoporous carbon composite has a great potential to be used as cathode material for high power lithium-ion batteries.
