Vanadium pentoxide nanofibers with diameters less than 100 nm and lengths of several micrometers were successfully synthesized by a simple hydrothermal method from the V2O5 xerogel with the addition of KMnO4 as an oxidant for preventing the vanadium ion from being reduced. The effect of experimental conditions on the nanocrystalline V2O5 characteristics has been investigated, such as pH value of the solution, reaction temperature, reaction time and kind of oxidants. The morphologies and the crystallographic structures of the final products were characterized by scanning electron microscopic images and X-ray powder diffraction (XRD) patterns. The electrochemical measurements of the cyclic voltammograms and charge-discharge curves were carried out to reveal the electrochemical properties of the final products.
