An amorphous nickel–cobalt–boron alloy as advanced pseudocapacitor material
Abstract
The nanoparticles of amorphous nickel–cobalt–boron alloy powder, prepared by chemical reduction, show superior specific capacitance when used as pseudocapacitor material. The amorphous nickel–cobalt–boron alloy exhibits a noticeable pseudocapacitance with 1310 F g−1 at 1.5 A g−1 in the electrolyte of 6 M KOH.
