This study aims to prepare electrode materials for energy storage devices through a facile glycol-assisted process. The synthesized polyhedron Cu-doped ZnS structure exhibits high specific capacitance and cycling stability, showing potential for next-generation energy storage devices.
The facile, efficient, and straightforward preparation of electrode material for energy storage devices has drawn considerable interest for practical applications. In this study, we have synthesized the polyhedron Cu-doped ZnS (ZnS:Cu) structure on carbon cloth (CC) using a single-step glycol-assisted process. The highly interconnected polyhedron shaped ZnS:Cu functions as positive electrode material in an aqueous electrolyte for supercapacitor application. The ZnS:Cu polyhedron-like structures with higher electroactive sites and synergistic effect exhibited higher specific capacitance of 468 F g-1 at 1 Ag-1 and cycling stability of 890.5% after 5,000 cycles. The better electrochemical performance and higher cycling stability of ZnS:Cu can be dedicated to interconnected polyhedron-like structures, doping of Cu in ZnS, and binder-free electrode design. This underlines the potential of the Cu-doped ZnS-based supercapacitor for next -generation energy storage devices.(c) 2022 Published by Elsevier B.V. on behalf of King Saud University.
