The hydrothermal method has been utilized to synthesize graphitic carbon nitride (g-C3N4) polymers and cobalt oxide composites effectively. The weight percentage of g-C3N4 nanoparticles influenced the electrochemical performance of the Co3O4-g-C3N4 composite. In an aqueous electrolyte, the Co3O4-g-C3N4 composite electrode, produced with 150 mg of g-C3N4 nanoparticles, revealed remarkable electrochemical performance. With an increase in the weight percentage of g-C3N4 nanoparticles, the capacitive contribution of the Co3O4-g-C3N4 composite electrode increased. The Co3O4-g-C3N4-150 mg composite electrode shows a specific capacitance of 198 F/g. The optimized electrode, activated carbon, and polyvinyl alcohol gel with potassium hydroxide were used to develop an asymmetric supercapacitor. At a current density of 5 mA/cm2, the asymmetric supercapacitor demonstrated exceptional energy storage capacity with remarkable energy density and power density. The device retained great capacity over 6k galvanostatic charge–discharge (GCD) cycles, with no rise in series resistance following cyclic stability. The columbic efficiency of the asymmetric supercapacitor was likewise high.

“…Optimized electrodes were used in hybrid supercapacitors with activated carbon (AC) with an area capacitance of 126.1 mF cm –2 and an energy density of 29.6 mWh cm –2 at a power density of 2.6 W cm –2 . 5000 cycles were performed at 5 mA cm –2 with a retention rate of 87% . Improvements over capacitors, higher energy density, and power density suggest that Co 3 V 2 O 8 may be an attractive material for SC electrodes.…”

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.
