For application as a pseudocapacitor electrode, highly porous CoO nanowalls are fabricated directly on 3D macroporous nickel foam (see images). A relatively high areal capacitance is achieved because of the porous structure. By grafting the porous nanowalls with another pseudocapacitive oxide, the a...
