This paper presents the synthesis, characterization, and fabrication of a prototype supercapacitor employing lead oxide nanoparticles (Pb₃O₄ Nps) dispersed reduced graphene oxide (rGO) nanocomposite as electrode material. Novel minium Pb₃O₄ Nps and the rGO platelets are synthesized using the precipitation method and modified microwave treatment. The various weight percentages of Pb₃O₄ Nps (1 wt%, 3 wt%, & 5 wt%) are blended with rGO using ultrasonication process followed by stirring process. The prepared nanomaterials are characterized to predict diffraction patterns, molecular vibrations, surface morphology, and elemental composition of Pb₃O₄ Nps, rGO, and Pb₃O₄-rGO nanocomposites. The Pb₃O₄-rGO nanocomposites are coated on the brass substrate and the charge storing characteristics of the electrode systems are evaluated using an electrochemical workstation which displays a remarkable specific capacitance value of 377F/g for Pb₃O₄-rGO nanocomposite prepared using 3 wt% Pb₃O₄ Nps coated electrode system at the scan rate of 5 mV/s and displays high retention stability of 95% after 2500 cycles. A prototype is fabricated in a pilot-scale study, where its charge-discharge behavior is demonstrated using a 9 V battery. After charging, a green light-emitting diode is activated for around 11 min while connecting 7 devices in series.
