ELECTRIC DOUBLE LAYER CAPACITOR, ITS MANUFACTURE AND ITS USE

摘要

PURPOSE:To provide an electric double layer capacitor whose large capacity and low internal resistance by a method wherein an active carbon block is used as a polarizing electrode and a conductive rubber is used as a collector. CONSTITUTION:An untreated collector which is composed of a conductive uncross-linked rubber is heated and compression-bonded to the outside surface of a polarizing electrode 2 composed of an active carbon block; the polarizing electrode 2 is bonded to the collector 5. Then, one pair of polarizing electrodes are arranged in such a way that their inside surfaces are faced; a separator 3 is laid and mounted between the inside surfaces. An untreated frame member which is composed of a nonconductive uncross-linked rubber is heated and compression-bonded to the outer circumferential face of the polarizing electrodes 2 in which the separator 3 has been laid and mounted between the inside surfaces; the polarizing electrodes 2 and the separator 3 are united by using the frame member 4. The polarizing electrodes 2 which have been bonded to the collectors 5 are impregnated individually with an electrolytic solution. Thereby, an electric double layer capacitor whose performance is uniform can be manufactured with good efficiency.
