A binder‐free self‐grown oxy‐hydroxide@nanoporous Ni‐Mn hybrid electrode with high capacitance and cyclic stability is fabricated by electrochemical polarization of a dealloyed nanoporous Ni‐Mn alloy. Combined with the low material costs, high electrochemical stability, and environmentally friendly nature, this novel electrode holds great promise for applications in high‐capacity commercial supercapacitors.
