Unique NiCo2S4@Ni3S2 core–shell nanotube arrays with a hierarchical structure, as promising positive electrodes for supercapacitors, were designed and synthesized on the surface of Ni foam via a hydrothermal reaction and electrodeposition method.
Developing high-performance, robust, and economic supercapacitor is a promising path to the future electric vehicle’s technology. Herein, a hierarchically porous CeO2 micro rice was attached on the Ni foam surface...
