Abstract:

CuO/CoS composite based electrodes are easy to synthesize using hydrothermal processes assist to develop high-performance supercapacitor materials in a sustainable way. The hydrothermal synthesis of CuO, CoS and CuO/CoS nanocomposite was reported here with an emphasis on energy storage devices. The physical characterization  are employed to evaluate textural, structural and morphological properties of manufactured material. Additional approaches for assessing electrochemical efficiency of materials are CA, CV, EIS and GCD by using Nickel foam as a conductive base under a 3-M KOH electrolyte. Electrochemically enhanced data demonstrated high specific capacitance (C_sp) of 1238 F/g at current density (j_d) of 1 A/g with power density (P_d) of 303 W/kg and energy density (E_d) of 63.38 Wh/Kg. This research not only highlights that CuO/CoS nanocomposite is an appropriate component for electrode development of supercapacitor, but also gives a novel approach for generating high-performing nanocomposite materials at a low cost that might be used in a number of upcoming energy storing applications.
