Patent ID: 8030832

Claim:
An electrode system for an electric device, comprising: (i) a first electrode which is a flat electrode; (ii) a second electrode which is a tube-type electrode, wherein the second electrode is formed by using: a) at least one metal selected from the group consisting of Au, Pt, Ag, Cu, Al, Cr, and alloys thereof; or b) at least one metal oxide selected from the group consisting of TiTO 2 , Indium Tin Oxide, ZnO, WO 3 , RuO 2 , IrO 2 , SnO 2 , and NiO; and (iii) a porous template having nanopores with a diameter of 5 nm to 500 nm, where the porous template is arranged on the first electrode, the porous template includes the second electrode inside of the nanopores for electrically being connected to the first electrode, and the porous template is formed of an anodized aluminum oxide, wherein the electric device is an electrochromic device, a solar cell, or a supercapacitor.
