<p>With an emphasis on supercapacitor applications, this work offers a straightforward, scalable method for creating binary composite designs for electrode materials. SrFe₂O₄ was combined with reduced graphene oxide (rGO) to make the composite. The creation of supercapacitors, which are prized for their high energy density, quick charging and discharging rates, extended life cycle, and affordability, is what makes this work significant. For electrochemical testing, nickel foam was used as the electrode substrate, and 3-M KOH solution as the electrolyte. The binary compound rGO-SrFe₂O₄ was produced via sol-gel auto-combustion before assessment.” The composite rGO-SrFe₂O₄ exhibited a specific capacitance of 445.4 F/g at a scan rate of 10 mV/s, as determined by electrochemical studies, highlighting the synergistic effect of rGO. Moreover, according to galvanostatic charge-discharge (GCD), the specific capacitance value for rGO-SrFe₂O₄ was found 425 F/g at 1 A/g. This study aims to pave the way for the development of cutting-edge materials with higher performance, broadening the scope of potential energy storage applications by revealing the synergistic effects of reduced graphene oxide with strontium ferrite in electrodes.</p>
