The present invention relates to a nano-porous electrode for a super capacitor and a manufacturing method thereof, and more specifically, to a nano-porous electrode for a super capacitor and a manufacturing method thereof wherein pores are formed on the surface or inside an electrode using an electrodeposition method accompanied by hydrogen generation, thereby increasing the specific surface area of the electrode and thus improving the charging and discharging capacity, energy density, output density, and the like of a capacitor. The method for manufacturing a nano-porous electrode for a super capacitor according to the present invention manufactures a nano-porous electrode using hydrogen generated by the electrodeposition as a template to minimize the amount of metal used, so that electrode manufacturing costs can be sharply reduced, the specific surface area of the electrode can be adjusted by a simple process, and also the charging and discharging capacity, energy density, output density, and the like of a capacitor can be improved by increasing the specific surface area.

A rare earth permanent magnet is prepared by immersing a portion of a sintered magnet body of R.sup.1—Fe—B composition (wherein R.sup.1 is a rare earth element) in an electrodepositing bath of a powder dispersed in a solvent, the powder comprising an oxide, fluoride, oxyfluoride, hydride or rare earth alloy of a rare earth element, effecting electrodeposition for letting the powder deposit on a region of the surface of the magnet body, and heat treating the magnet body with the powder deposited thereon at a temperature below the sintering temperature in vacuum or in an inert gas.

A nanoporous metal structure is made by etching a metal alloy structure of two or more metals. Less than all of the metals are selectively removed (e.g., dissolved in solution) from the alloy in the presence of an alternating voltage profile, for example, a periodic voltage profile. The resulting nanoporous metal structure, having pore openings of about 20 nm to about 500 nm in diameter and a purity of at least about 70%, can be further treated to alter some or all of the structure, and/or to add, remove and/or modify properties thereof.
