<p>MoS₂/WO₃ nanocomposites were effectively manufactured with multiple weight ratios, which include MW-1 (4:6) and MW-2 (1:1), through hydrothermal and wet chemical technique. The XRD experimental findings suggested that the crystalline crystallinity of the created nanocomposite with a ratio of (4:6) was boosted. MW-1 suggested a raised specific capacitance of 331 Fg⁻¹ at 1 Ag⁻¹ of current due to the synergistic effect within Mo⁴⁺ and W⁶⁺ ions and their distinctive surface properties. The asymmetric supercapacitor (ASC) was set up by employing MoS₂-based tungsten oxide electrode components as the cathode and activated carbon (AC) as the anode. The ASC operated satisfactorily at a significant potential variance of 1.2 V. Contrary to sulfide and oxide-based supercapacitors that were earlier explored, the MW-1//KOH//AC ASC produced an energy density of 17.4 Whkg⁻¹ at a power density of 602 Wkg⁻¹, which was impressive. MW-1//KOH//AC ASCs indicated cyclic consistency of 86% at 2 Ag⁻¹ with a potential variation of −0.7 to 0.5 V, as witnessed by over 5000 continuous GCD cycles. The conclusions revealed that the nanocomposite that was developed had significant potential for use in supercapacitor applications with an effective ratio of (4:6) (MW-1).</p>
