<p>A novel electrode material for redox capacitor that realizes high specific capacity, high output density, high energy density, high stability and low cost; and a process for producing the same. There is provided an electrode material for redox capacitor, comprising a nano-structure of <=50 nm size constituted of an amorphous oxide of at leas one metal selected from the group consisting of manganese, nickel, tin, indium, tungsten, molybdenum, vanadium, cobalt, titanium and iron, or comprising the nano-structure together with a porous material of conductive polymer. This electrode material can be produced by a process comprising the step of conducting electrodeposition on an electrode surface with the use of an aqueous solution of compound containing the above metal as an electrolytic solution according to a potential scanning electrodeposition technique of >=70 mV/s potential scanning rate and optionally further comprising the step of conducting electrodeposition of a porous material of conductive polymer with the use of an aqueous solution containing a monomer of conductive polymer as an electrolytic solution according to the potential scanning electrodeposition technique of >=70 mV/s potential scanning rate.</p> |
