Popis: | A novel symmetric supercapacitor electrode material, rGO-SnO2-polyaniline nanocomposite,was synthesized using graphite oxide, SnCl2.2H2O, and pure Aniline as precursors in a scalable and straightforward one-pot process. Analysis revealed that the rGO-SnO2-polyaniline composite had been successfully synthesized. When the two-electrode supercapacitor was assembled using 1M H2SO4, it showed an outstanding specific gravimetric capacitance of 524.2 F/g at a 5 mV/s scan rate. To the best of our knowledge, such a higher value for a two-electrode specific capacitance for a supercapacitor was never reported.Furthermore, even at a high current density of 1 A/g, the material disclosed an outstanding charge-discharge characteristic. Thus, the rGO-SnO2-polyaniline nanocomposite couldalso be used as an electrode for commercial supercapacitors. |
