摘要：

Composite material based supercapacitors have attracted interest as promising green and efficient candidates in energy storage application. In the present work, the copper oxide/nickel oxide (CuO/NiO) and its carbon composite with hetero atom (N) doped graphene (CuO/NiO/N-rGO) were successfully synthesized by probe sonication assisted solvothermal procedure and used as active electrodes in supercapacitor application. The CuO/NiO/N-rGO composite material was utilized as an electrode in supercapacitor and exhibited specific capacitance of similar to 220 F g(-1) at a current density of 0.5 A g(-1). Significantly, capacitance retention of the electrode was found to be 97% even after 5000 charge-discharge cycles. The high electrochemical performance and cyclic stability of CuO/NiO/N-rGO indicated the composite to be a promising candidate for supercapacitor applications. (C) 2020 Elsevier B.V.
