N2 - In recent years, supercapacitors attracted researchers as a potential replacement for electrochemical energy storage devices primarily because of their remarkable power density and significantly extended cycle life. This research focuses on synthesis of novel BaCeO3 and BaCeO3@rGO nanohybrids fabricated via hydrothermal route for supercapacitor devices. Various physical and electrochemical analytical techniques used for characterization of fabricated electrode samples. The galvanostatic charge discharge (GCD) plot used to analyze prepared pure BaCeO3 and BaCeO3 @rGO samples. The specific capacitance value for BaCeO3 646 F g−1 and 1488 F g−1 for BaCeO3@rGO. The energy density was also measured to be 65 Wh Kg−1 and power density 324 W kg−1 at 1 A g−1. The incorporation of reduced graphene oxide into BaCeO3 improves conductivity provides more active number of sites enhanced surface area and favors quicker charge transportation which leading to an increase in capacitance. The electrochemical stability fabricated composite that it exhibits stability even after undergoing 5000th cycles. The outstanding efficiency of supercapacitor applications is attributed to mechanical versatility, strong cooperation and combined effects of BaCeO3 and rGO nanosheets. The Nyquist plot investigates lower value of charge transfer resistance 0.87 Ω for BaCeO3@rGO nanohybrids. The observed significant stability of material suggests its potential as a highly prospective candidate for advancing next-generation energy storage devices.
