In this study, excellent performance and wide operating voltage are obtained with an aqueous electrolyte. Aqueous electrolytes attracted more attention than other (such as organic solvents, ionic liquids) in supercapacitor applications because of their safety, low cost, nontoxicity. Polypyrrole (PPy), aniline 2-sulfonic acid (ASA) modified electrodes hydrothermal synthesized on carbon felt (CFt) for applications. We investigate the presence concentration ASA polymerization PPy. Furthermore, a high 3.0 V asymmetric (ASC) graphite plate is assembled 3 M KCI. CFt/PPy/ASA(0.02)//GP exhibits specific capacitance value 902.9 F g−1 at 5 mV s−1 after 5000 cycle-life testing 93.6% retention scan rate 1000 s−1.
