Electrodeposited nickel hydroxide on nickel foam with ultrahigh capacitance

Abstract
Electrodeposited Ni(OH)2 on nickel foam with porous and 3D nanostructures has ultrahigh capacitance in the potential range −0.05–0.45 V, and a maximum specific capacitance as high as 3152 F g−1 can be achieved in 3% KOH solution at a charge/discharge current density of 4 A g−1.
