Abstract
A facile ultrasonic-assisted synthesis (UAS) technique was employed to synthesize bare (BWO-Bare) and heat-treated 600 °C Bi2WO6 nanostructures (BWO-600), which serve as an affordable and ecofriendly supercapacitor electrode material. Extensive structural, morphological, and electrochemical investigations on BWO-600 revealed homogeneous dispersion, exhibiting a remarkable specific capacity of 614 C/g (6 M aqueous KOH electrolyte) in a three-electrode configuration and 376 C/g when assembled as a symmetric supercapacitor. BWO-600 exhibited impressive cyclic stability with a capacitance retention of 84% after 10,000 cycles in 6 M KOH. According to the Dunn and Trasatti analytical method, BWO-600 exhibits an 82% diffusive contribution and an 18% capacitive contribution at a relatively low scan rate. The BWO-600 symmetric supercapacitor demonstrates its effectiveness across diverse electrochemical applications with a remarkable peak energy density of 20.8 Wh/kg and power density of 4.1 kW/kg.
