The rapid progress of various renewable energy conversion methods has driven an increasing demand for efficient energy storage systems. Transition metal oxides are widely utilized as electrodes in supercapacitor devices; nonetheless, however, they suffer from significant drawbacks such as limited surface area and inadequate conductivity. Doping has been recognized as an efficient approach to overcome these limitations. This current research utilized a hydrothermal technique to increase the capacitive characteristics of CoMoO3 by doping with barium ion (Ba2+). Several physical studies were utilized to confirm the crystal structure, enhanced morphology and surface area of Ba-doped CoMoO3, while the physiochemical parameters of doped electrode sample were assessed using several analytical techniques. The examination of energy storage applications included a 3.0 M KOH for performing cyclic voltammetry (CV) studies, galvanic charge–discharge (GCD), and electrochemical impedance spectroscopy (EIS). Ba-doped CoMoO3 nanocomposites exhibit significant Cs values of approximately 1001 F/g with Ed of (20.48 Wh/kg) and Pd of (192 W/kg) showcasing superior charge–discharge cyclic performance. The Ba-doped CoMoO3 electrode material exhibited superior electrochemical properties, rendering it a viable candidate for future supercapacitor devices.
