Porous NiCo2O4/C nanofibers replicated by cotton template as high-rate electrode materials for supercapacitors

Porous NiCo2O4/C nanofibers are replicated with cotton as template via hydrothermal route. The as-prepared products are directly evaluated as electrode materials for supercapacitors. The electrode material exhibits high specific capacitance and outstanding rate capability, which can be accounted for the novel porous nanostructure.
