Vertically aligned mixed V2O5–TiO2 nanotube arrays for supercapacitor applications

Author affiliations

Abstract

Highly ordered mixed V2O5–TiO2 nanotubes can be formed by self-organizing anodization of Ti–V alloys with vanadium content of up to 18 at%. In the resulting oxide nanotube arrays, the vanadium is electrochemically switchable leading to a specific capacitance that can reach up to 220 F g−1 and an energy density of 19.56 Wh kg−1 with perfect reversibility and long-term stability. Thus these mixed oxide nanotubes may be considered as a promising candidate for supercapacitors.
