Fabrication of nickel-foam-supported layered zinc–cobalt hydroxide nanoflakes for high electrochemical performance in supercapacitors†
Abstract
Nickel foam supported Zn–Co hydroxide nanoflakes were fabricated by a facile solvothermal method. Benefited from the unique structure of Zn–Co hydroxide nanoflakes on a nickel foam substrate, the as prepared materials exhibited an excellent specific capacitance of 901 F g−1 at 5 A g−1 and remarkable cycling stability as electrode materials in supercapacitors.
