An ultrathin film of V2O5 is electrodeposited on the surface of carbon nanofibers to obtain a high surface area with an improved electrode conductivity. This provides a high pseudocapacitance of 1308 F g−1 with respect to the effective contribution from the deposited oxide layer. The schematic shows the distribution of V2O5 throughout the nanofiber. The graph shows the dependence of the specific capacitance on the deposited amount of V2O5.
