Nickel copper cobalt oxide (NiCuCoO) ternary metal oxide nanoparticles were synthesized by employing the hydrothermal method. NiCuCoO electrode demonstrates a specified capacity of 596 C g⁻¹ at 1 A g⁻¹, high capacitance retaining of 99% even if 1000 sequences at the density of current 10 A g⁻¹, and significant extended cyclic strength over 1000 sequences. The gathered asymmetric supercapacitor (ASC) tool via NiCuCoO as the cathode and activated carbon as anode materials achieve a specified capacity of 168 C g⁻¹ at a current density of 1 Ag⁻¹, an excellent capacity retaining of 95% even later than 5000 sequences at a density of current 10 A g⁻¹. The fabricated device exhibits a high density of energy and power is 96 Wh kg⁻¹ and 841 W kg⁻¹. The prepared material confirms an excellent capacitance routine, so this work represents for a next-generation energy storage device.
