Facile synthesis of MnO2@NiCo2O4 core–shell nanowires as good performance asymmetric supercapacitor

Hierarchical MnO 2 @NiCo 2 O 4 core–shell nanostructures are well fabricated via a simple two-step hydrothermal process. The MnO 2 @NiCo 2 O 4 core–shell nanostructures materials electrode presents a high capacitance of 684 F g −1 at 2 A g −1 current density, 40 times higher than that of the single...
