dc.description.abstractIn this study, we synthesized binder-free NiCo<sub>2</sub>O<sub>4</sub>@NiCo<sub>2</sub>O<sub>4</sub> nanostructured materials on nickel foam (NF) by combined hydrothermal and cyclic voltammetry deposition techniques followed by calcination at 350 &deg;C to attain high-performance supercapacitors. The hierarchical porous NiCo<sub>2</sub>O<sub>4</sub>@NiCo<sub>2</sub>O<sub>4</sub> structure, facilitating faster mass transport, exhibited good cycling stability of 83.6% after 5000 cycles and outstanding specific capacitance of 1398.73 F g<sup>&minus;1</sup> at the current density of 2 A&middot;g<sup>&minus;1</sup>, signifying its potential for energy storage applications. A solid-state supercapacitor was fabricated with the NiCo<sub>2</sub>O<sub>4</sub>@NiCo<sub>2</sub>O<sub>4</sub> on NF as the positive electrode and the active carbon (AC) was deposited on NF as the negative electrode, delivering a high energy density of 46.46 Wh kg<sup>&minus;1</sup> at the power density of 269.77 W kg<sup>&minus;1</sup>. This outstanding performance was attributed to its layered morphological characteristics. This study explored the potential application of cyclic voltammetry depositions in preparing binder-free NiCo<sub>2</sub>O<sub>4</sub>@NiCo<sub>2</sub>O<sub>4</sub> materials with more uniform architecture for energy storage, in contrast to the traditional galvanostatic deposition methods.
