Achieving Self-Supported Hierarchical Cu(OH)(2)/Nickel–Cobalt Sulfide Electrode for Electrochemical Energy Storage

Herein, nickel–cobalt sulfide (NCS) nanoflakes covering the surface of Cu(OH)(2) nanorods were achieved by a facile two-step electrodeposition strategy. The effect of CH(4)N(2)S concentration on formation mechanism and electrochemical behavior is investigated and optimized. Thanks to the synergistic...

description Herein, nickel–cobalt sulfide (NCS) nanoflakes covering the surface of Cu(OH)(2) nanorods were achieved by a facile two-step electrodeposition strategy. The effect of CH(4)N(2)S concentration on formation mechanism and electrochemical behavior is investigated and optimized. Thanks to the synergistic effect of the selected composite components, the Cu(OH)(2)/NCS composite electrode can deliver a high areal specific capacitance (Cs) of 7.80 F cm(−2) at 2 mA cm(−2) and sustain 5.74 F cm(−2) at 40 mA cm(−2). In addition, coulombic efficiency was up to 84.30% and cyclic stability remained 82.93% within 5000 cycles at 40 mA cm(−2). This innovative work provides an effective strategy for the design and construction of hierarchical composite electrodes for the development of energy storage devices.
