Hierarchical CuCo2S4 hollow nanoneedle arrays have been firstly synthesized on a Ni foam using a facile template-free hydrothermal method and applied as novel binder-free electrodes for high-performance asymmetric supercapacitors.
The unique P-Ni(OH)2@MnO2 core–shell nanoarrays heterostructure grown on Ni foam were designed and synthesized as a binder-free electrode, high power and energy density asymmetrical supercapacitors were achieved.
Herein, binder-free sponge-like NiCo2S4 nanosheets supported on Ni foam with ultra-high mass loading were synthesized via a facile one-step hydrothermal route.
CoMn2O4@Co3O4 core/shell arrays on Ni foam exhibit outstanding electrochemical performance for asymmetric supercapacitors with respect to high specific capacitance and high cycling stability.
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...
