Abstract
Modern-era energy crises have arisen as a result of industry's quick expansion. There must be a proliferation of autonomous, renewable-energy-powered, high-capacity storage systems. The high specific capacitance (Cs) is a result of the Electric Double Layered Capacitors (EDLC's) stellar cathode characteristics. The remarkable conductivity and storage capacity of transition metal nitride-based oxides (TMOs) have made them an attractive option for use as cathode materials in SC devices. The present study successfully synthesized the TiN-CuO composite for electrode material by employing the straightforward wet-chemical method. But the fact that the TiN-CuO combination is crystalline suggests it could be used as an electrode in SCs. The electrochemical performance of the TiN-CuO electrode was also highlighted by its excellent Cs of 843.5 F g−1. Furthermore, the TiN-CuO‖MnO2-KOH electrode displays a power density (Pd) of 17595 W/kg and an energy density (Ed) of 44.88 Wh kg−1. In addition, the TiN-CuO‖MnO2-KOH electrode has shown remarkable cyclic stability of 97.3 % up to 10,000 cycles, at 10 A g−1. The electrochemical characteristics of fabricated TiN-CuO electrode material are superior to those of pure materials, rendering it an attractive candidate for use in energy storage devices such as SCs.
