Abstract

Recent progress in supercapacitors—recognized as advanced and high-potential energy storage devices—has drawn considerable interest from both scientific and industrial sectors. In this study, a simple, rapid, and highly effective synthesis method is introduced, offering strong potential for scaling up to industrial production. The research focuses on synthesizing an electrode containing CuCrO₂ nanocomposite using different proportions of CuCrO₂, carbon black (CB), and activated carbon (AC). The resulting nanoparticles and electrodes were analyzed through structural and performance-based assessments. FESEM imaging revealed that the electrode materials were evenly distributed across the nickel foam substrate. Among all the synthesized composites, the one combining CuCrO₂ (0.6 %wt) with a carbon-based material (0.4 %wt) delivered the best electrochemical performance, achieving a specific capacitance of 700 F.g⁻¹ and stability of 91% after 5000 charge-discharge cycles at a current density of 1 A.g⁻¹.
