PURPOSE:To increase contact area with an electrolyte and facing area with a counter electrode without cracks, coming-off, or breakage which may happen in winding operation of a sheet-shaped electrode by using an electrode prepared by cylindrically molding a conductive polymer. CONSTITUTION:An electrode prepared by cylindrically molding a conductive polymer is used. A cylindrical shape is preferable but a prismatic shape such as triangle, square, and hexagonal shape is allowable. The cylindrical mix electrode can be in contact with an electrolyte on both sides of outer surface and inner surface, and also can be faced with counter electrodes on both sides. If cylindrical mix type electrodes having different sizes are arranged concentrically and separators and counter electrodes are arranged between these electrodes, large area is ensured like a spiral type. In addition, problems such as cracks, coming-off, and breakage which may happen in winding operation of a sheet- shaped electrode are avoided. |
