Graphene-based materials have been widely studied in the field of supercapacitors. However, their electrochemical properties and applications are still restricted by susceptibility graphene-based to curling agglomeration during production. This study introduces a facile method for synthesizing reduced graphene oxide (rGO) nanosheets activated carbon based on olive stones (OS) with polyaniline (PAni) surface decoration development Several advanced techniques were used examine structural samples. The obtained PAni@OS−rGO (1:1) electrode exhibits high capacity 582.6 F·g−1 at current density 0.1 A·g−1, an energy 26.82 Wh·kg−1; thus, it demonstrates potential efficacious storage. In addition, this material remarkable cycling stability, retaining over 90.07% capacitance loss after 3000 cycles, indicating promising long cycle life. Overall, research highlights biomass-derived OS presence PAni rGO advance high-performance

Abstract Supercapacitor's demand for hybrid vehicles, portable electronic gadgets, and high‐power applications is increasing unexpectedly. However, supercapacitors′ inadequacies (i. e., inflated costs, poor energy density, erratic cycle life) need to be addressed by introducing novel composite materials developing facile synthesis techniques which can give them high surface area improved electrochemical stability. Moreover, supercapacitor electrodes based on ternary composites should designed broaden their application range deal with the challenges. The primary aim of this review explore recent advances in field supercapacitors address challenges field. Specifically, we have focused nanocomposites comprising Graphene‐Conducting Polymers‐Metal Oxides (G‐CPs‐MOs) Sulfides (G‐CPs‐MSs). Our investigations centred around exploring various techniques, morphology analysing reported evaluations highlight potential prospects they present.
