Enhancing supercapacitor electrochemical performance through innovative energy storage materials and controlled assembly growth is a popular and promising strategy. This study introduces a novel battery-type electrode material with a core-shell structure based on zinc and copper oxides, synthesized via a straightforward, environmentally friendly two-step electrodeposition process. The electrode materials, composed of ZnO and CuO oxides (CuO@ZnO), were directly deposited onto a three-dimensional conductive nickel foam (NF) substrate to form a binder-free ultra-thin multilayer (CuO@ZnO/NF). At a current density of 2 mA.cm−2, the CuO@ZnO/NF nanomaterial exhibits a significant specific capacity of 6123.3 mF.cm−2. Impressively, it maintains a high cycling stability of 95% after 8,000 cycles. This research highlights the potential of core-shell structured electrodes to advance supercapacitor technology, offering efficient energy storage solutions suitable for renewable energy applications and beyond.

摘要

Enhancing supercapacitor electrochemical performance through innovative energy storage materials and controlled assembly growth is a popular and promising strategy. This study introduces a novel battery-type electrode material with a core-shell structure based on zinc and copper oxides, synthesized via a straightforward, environmentally friendly two-step electrodeposition process. The electrode materials, composed of ZnO and CuO oxides (CuO@ZnO), were directly deposited onto a three-dimensional conductive nickel foam (NF) substrate to form a binder-free ultra-thin multilayer (CuO@ZnO/NF). At a current density of 2 mA.cm−2, the CuO@ZnO/NF nanomaterial exhibits a significant specific capacity of 6123.3 mF.cm−2. Impressively, it maintains a high cycling stability of 95% after 8,000 cycles. This research highlights the potential of core-shell structured electrodes to advance supercapacitor technology, offering efficient energy storage solutions suitable for renewable energy applications and beyond.
