Raktima Basu, Sandip Dhara
Abstract
In recent years, vanadium oxides have gained immense attention in the field of energy storage devices due to their low-cost, layered structure and multi-valency despite their limited electrical conductivity and lower structural stability. In this brief review, we have focused on electrochemical properties of the stoichiometric vanadium oxides along with VOx composites. The morphology engineering, doping with heteroatom and formation of composites with carbon-based materials and/or conducting polymers in enhancing the supercapacitive performances of the vanadium oxides are discussed in detail. Finally, the potentiality and challenges of vanadium oxides nanocomposites for supercapacitor applications are discussed.
