“…VOP nanocomposites exhibit a unique nanorod structure and excellent electrical properties, making them an emerging material for use as electrode materials in supercapacitor applications. 84 Pullanchiyodan et al used two-dimensional transition metal disulfide (molybdenum disulfide (2D MoS 2 )) and transition metal oxide (vanadium pentaoxide, V 2 O 5 ) as negative and positive electrodes, respectively, to make hybrid supercapacitors (HSCs). By combining these positive and negative electrodes in a 1 M Na 2 SO 4 water-based electrolyte, the developed HSC showed an operating potential of 2.0 V. The area capacitance and energy density of HSC were 30 mF cm −2 and 8.2 μWh cm −2 , respectively, at a scanning rate of 1 mV s −1 for the electrochemical analysis of HSC at a stable operating potential of 1.4 V. After 5000 energy storage materials, ultrathin twodimensional transition metal oxide materials have great advantages.…”

In the direction of novel energy materials, one area of intense research focus is creating new electrode materials to enhance the electrochemical performance of supercapacitors. Compared to other metal elements, vanadium has numerous valence states (+2 to +5). Materials based on vanadium oxide will show various electrochemical characteristics, which makes choosing the electrode material for a supercapacitor quite convenient. They still have a lot of room to increase the electrochemical performance of their electrode materials, which might be very useful in large-scale commercial supercapacitor applications. This review focuses on effective ways of improving the electrochemical performance of metal-and vanadium oxide-based electrode materials. To develop unique structures with more REDOX active sites, various synthesis approaches have been used, including carbon-based composites and the addition of transition metal cations. Future prospects and difficulties are addressed along with existing research approaches to clarify how advances in these materials can improve the use of supercapacitors.
