Abstract
The present communication reports on the first electrodeposition of Ni(OH)2 on ZnO array supported on Ni foam. When applied as a binder-free electrode material for pseudocapacitive energy storage, the resulting ZnO@Ni(OH)2 array exhibits a high specific capacitance of 2028Â FÂ gâ1 at a current density of 10Â AÂ gâ1 with good cycling stability. Meanwhile, the array exhibits a superb rate capability. Even at an extremely high current density of 100Â AÂ gâ1, the array still shows a very high specific capacitance of 1059Â FÂ gâ1.
