Abstract:

As a promising electrode material, vanadium pentoxide (V2O5) has the advantages of abundant reserves, non-toxicity and high capacitance potential. The material properties can be optimized through the strategies of V2O5 nanosizing and compounding. This paper reviewed the recent applications of V2O5/C nanocomposites in the fields of supercapacitor energy storage. The preparation methods of V2O5/C nanocomposites with different dimensions, the influence on morphology and electrochemical performance were summarized. Strategies for enhancing the electrochemical properties were discussed via the component optimization, increasing effective specific surface area, heteroatom doping and constructing ternary nanocomposites. V2O5/C nanocomposites overcame the limitations of single electrode materials with their unique structure and excellent efficiency, which had strong practical application potential. Finally, the problems faced by V2O5/C electrode materials in terms of performance improvement, mechanism exploration and large-scale production were proposed, and the future development trend of electrochemical energy storage technology were presented, that is, the development of high-performance and intelligent new composite materials or energy storage devices, which provided theoretical and practical support for the construction of efficient and safe electrochemical energy storage systems.
