Here, we report the electrochemical performance of a polyaniline based porous ternary composite (PNHFeG) electrode material as supercapacitor, using a binary composite (NHFeG) that involves combination of flower-like nanostructured Ni(OH)2 and iron oxides-doped reduced graphene oxide (Fe-RGO). PNHFeG ternary composite was prepared through in-situ oxidative polymerization of aniline in the presence of NHFeG. The porous ternary PNHFeG composite with high surface area (239 m2g-1) notably exhibits maximum specific capacitance (Csp) of 2714 F/g at 5 A/g current density, along with 98.5% retention of its initial capacitance even after 2000 cycles. Moreover, even at a higher current density of 30 A/g, the composite electrode material maintains a remarkable Csp value of 1223 F/g. Finally, the PNHFeG electrode material reveals a power density of 1498 W/kg, along with a maximum energy density of 135.7 Wh/kg at 5 A/g, suggesting the current composite electrode material can be considered as a promising candidate for high-performance supercapacitor applications.
