To address the issue of excessive use of fossil fuels, which are causing environmental pollution; researchers are continuously exploring for alternative energy sources. Although a greater no of renewable energy production devices has been explored but storage is still a big problem. Supercapacitor are the well-known and effective energy storage device. Here, rGO was combined with spinel-based metal oxide to synthesize a BaFe2O4/rGO electrode using hydrothermal procedure. The material exhibited significant surface zone, as determined through Brunauer–Emmett–Teller (BET) study. Scanning electron microscopy (SEM) confirmed that BaFe2O4 was uniformly and tightly distributed over the rGO surface. The synthesized electrode displayed high Cs of 1498.673 F g−1, an Ed of 54.693 Wh kg−1 and Pd of 256.3 W kg−1 at jd of 1 A g−1. Moreover, Nyquist graph shows lowest solution impedance (Rs) of 0.75 Ω, signifying excellent electrical conductivity. The material also maintained its performance after 5000th cycles, demonstrating impressive stability. This study highlights the innovative design of BaFe₂O₄/rGO nanocomposite, where incorporation of rGO effectively addresses poor conductivity of pristine BaFe₂O₄, thereby enhancing its electrochemical performance for supercapacitor (SCs) applications.
