Facile synthesis of nickel–cobalt double hydroxide nanosheets with high rate capability for application in supercapacitor
Source abstract
Abstract
In this work, nickel–cobalt double hydroxide nanosheets with high rate capability are prepared by a facile epoxide precipitation route. The synthetic procedure includes an oxidization step using ammonium persulfate as oxidant and a precipitation step using propylene oxide as precipitation agent. As shown in the results of electrochemical characterization, high specific capacitance of 2548 F g−1 for this material can be obtained at current density of 0.9 A g−1 in aqueous solution of 3 mol L−1 KOH. It is surprising to notice that the capacitance of material still remains 1587 F g−1 at high current density of 35.7 A g−1. These results demonstrate that the as-prepared nickel–cobalt double hydroxide nanosheets are promising electrode material for supercapacitor application as a primary power source.
