Abstract
Nickel-cobalt sulfide arrays with different loading densities were fixed on nickel foam via a facile hydrothermal method in ethanol. Their loading densities could be easily adjusted via changing the amount of reactants. It was found that the nickel-cobalt sulfide arrays on Ni foam with moderate loading density showed excellent electrochemical performance for supercapacitors. The best sample not only exhibited an outstanding areal capacitance of 4.84 F cm−2 at 10 mA cm−2 but also showed the best cycle stability and rate performance compared with the samples with other loading densities. Remarkably, this method to control the loading densities of nickel-cobalt sulfide on nickel foammay provide a new strategy for the investigation of other nanoarrays on various substrates for catalysts and lithium-ion batteries other than supercapacitors.
