Abstract: . A highly efficient nickel/copper oxide-PANI grafted nitrogen-doped reduced graphene oxide (NiCu-PANI/N-rGO) nanocomposite electrode material was developed for hybrid supercapacitors (HSCs). The prepared HSC achieved an excellent specific capacitance of 290 F g−1 at the current density of 1.5 A g−1. The rate capability of the device was recorded as 37% at 10 A g−1 current density and the calculated energy density was also recorded as 32.6 W h kg−1 at the power density of 670 kW kg−1. After 8000 charge-discharge cycles in the KOH electrolyte solution, an excellent capacitance retention (82%) was realized. These findings effectively illustrated the possible uses of the manufactured hybrid supercapacitor to mitigate upcoming energy demands.
