AB - Due to the severity of environmental degradation and depletion of natural energy resources, research on sustainable energy storage systems have become quite popular. Supercapacitor is one of the most innovative and promising type of energy storage devices. The effective performance of supercapacitor greatly depends on the electrode material. Therefore, new type of nanocomposite has been fabricated with βCD-stabilized CuO nanoparticles (CuO-βCD NPs) on Co-Al layered double hydroxide (Co-Al LDH) utilizing solvothermal process. The wet impregnation technique facilitates the formation of three distinct CuO-βCD/Co-Al LDH nanocomposites in the ratios of 1:1, 1:2, and 2:1 by promoting the growth of CuO-βCD on Co-Al LDH in corresponding compositions. Synthesized nanocomposites are characterized using a variety of spectroscopic techniques. The average pore size of 2:1 CuO-βCD/Co-Al LDH is 1.7 nm whereas the specific surface area and approximate pore volume of this nanocomposite are 38.306 m2 g−1 and 0.043 cm3 g−1, respectively. Electrochemical investigations like cyclic voltammetry (CV), galvanostatic charge–discharge (GCD), electrochemical impedance spectroscopic (EIS) measurements and along with cycle stability studies are performed to examine the electrochemical performance of synthesized nanocomposites. The 2:1 ratio has revealed improved specific capacitance (SC) of 1567 F g−1 at 0.45 A g−1 in 1 M potassium hydroxide medium in three electrode systems and maintains 76% of its original SC even after 5000 cycles. The improved electrochemical performance of 2:1 ratio reveals the appropriateness of this material as an effective electrode for supercapacitor application.
