Three dimensional Ni foam-supported graphene oxide for binder-free pseudocapacitor
Abstract 3D Ni foam-supported graphene oxide (3D-NiGO) have been fabricated by simply
impregnating commercially Ni foam into graphene oxide solution. The resulted 3D-NiGO can
be directly used as pseudocapacitor electrode without current collector and binder and also
as support for MnO 2 nanowires (3D-NiGOM). Both 3D-NiGO and 3D-NiGOM-based binder-
free pseudocapacitors show high specific capacitance, good rate capability and excellent
cycle stability.
