In this study, macro-porous metallic material was prepared by template method using epoxy monolith, and was electrochemically characterized as a battery current collector. The metallic monolith had a thin metallic skeleton with thickness of 100-200 nm, and showed high porosity and large surface area. For its application as battery electrode, redoxactive NiCo2O4 nanowire array was hydrothermally deposited on the monolithic current collector, and the electrochemical performance was examined by cyclic voltammetry and constant current charge-discharge (CD) measurements comparing with a conventional metallic nickel foam current collector. These results indicate that the monolith electrode was superior in the specific capacitance and CD rate characteristics to the foam electrode.
