A supercapacitor (SC) is a device that possesses outstanding potential to impart significant breakthroughs in energy storage. The current study deals with an experimental investigation in developing NiCo layered double hydroxides/reduced graphene oxide/ Bismuth sulfide ()nanocomposites and exploring its characterization as well as electrochemical measurement. Efficient straightforward and adaptable synthetic approach is implemented to prepare the nanocomposite. In the present investigation XRD, SEM, EDS, TEM, Raman spectroscopy are applied for the characterization while CV, GCD are used for electrochemical measurement of the nanocomposite. In the present study, the as-prepared nanocomposite exhibits rod type structure. The nanocomposite exhibits a decreased band gap and greater free electrons, suggesting that the nanocomposite favors electron transport. The nanocomposite possesses significantly high specific capacitance value of 1139 F/g at current density (CD) of 1 A/g compared to that of NiCo-LDHs/rGOand. Further, the nanocomposite exhibits energy density (ED) of 36.86 Wh/kg and power density (PD) of 919 W/kg at a current density of 1 A/g. Because of its non-toxicity, plentiful availability, environment friendly and cost effectiveness, the as-developed nanocomposite finds significant real-world applications in SCs.
