Development of BaMoO3/PANI nanocomposite for enhanced performance of supercapacitor applications

초록

Nowadays, supercapacitors (SCs) have got focus as a feasible substitute for energy storing devices (ESDs), specifically regarding exceptional power density (Pd) and considerably longer life cycle. Transition metal-based perovskite oxides are interesting substances for SCs electrodes because they have an affordable price and high specific capacitance. In this investigation, a BaMoO3/PANI nanocomposite was fabricated with a facile and affordable hydrothermal route. Several methods mainly physical and electrochemical were adopted to characterize constructed electrode substance. The Brunner-Emmett-Teller (BET) study exhibited that BaMoO3/PANI nanocomposite had a substantial specific surface area (SSA) and scanning electron microscopy examinations showed that BaMoO3 was evenly distributed on PANI. The electrochemical analyses of the manufactured BaMoO3/PANI nanocomposite was conducted by three-electrode setup in 3.0 M KOH. However, the BaMoO3/PANI nanocomposite displayed a greater specific capacitance (Cs) of 1007.71 F/g, Pd of 194.5 W/kg and energy density (Ed) of 21.17 Wh/kg at 1 A/g with exceptional cyclic stability after 3000th cycle. Hence, the BaMoO3/PANI nanocomposite is prospective electrode substance for multiple commercial applications as well as future ESDs.
