Microstructures of the electrochemically prepared V2O5 center dot xH(2)O on the CNT film substrate (V2O5 center dot xH(2)O/CNT film electrode) showed that V2O5 center dot xH(2)O was heterogeneously nucleated and uniformly deposited on the CNT film substrate. The V2O5 center dot xH(2)O/CNT film electrode showed not only a high specific Li-ion capacitance of 1230 F/g with respect to the mass of the V2O5 center dot xH(2)O, but also a high rate capability. The maximum specific energy of 851 Wh/kg and specific power of 125 kW/kg were obtained from the discharging curves of the V2O5 center dot xH(2)O/CNT film electrode. They could be attributed to the electrode construction comprising a very thin film of V2O5 center dot xH(2)O deposited on the conductive CNT film substrate with a three-dimensional nanoporous structure.
