Recently energy storage has become a big issue since most of the energy devices have either low energy and/or power densities. So it is essential to develop highly capacitive energy storage devices. Among energy storage devices, pseudocapacitive energy storage devices (Supercapacitors) have been attracting great attention because of its intermediate position of energy and power density on the Ragone plot. Several materials are being investigated for enhancement of the energy and power density of the supercapacitors. Among various materials, especially vanadium pentoxide (V2O5) is one of the most attractive materials because it has high theoretical capacity due to several oxidation states enabling multiple electron transfer. Various wet chemical methods have been used to prepare V2O5, however these methods time consuming, require additional binders to form the electrodes. Herein, we fabricated vertically aligned V2O5 nanostructure directly on the vanadium metal substrate by anodization and evaluated electrochemical performances for high energy density electrochemical application.
