ELECTRIC DOUBLE LAYER CAPACITOR AND METHOD FOR MANUFACTURING THE SAME |
摘要 |
<p>In an electric double-layer capacitor, resistance of a polarizable electrode layer is reduced and gas generation inside a case is suppressed in an attempt to improve reliability. On that account, an electric double-layer capacitor is provided, which is obtained by housing in a case, together with a driving electrolyte, a capacitor element wound with a separator interposed between electrodes being paired anode and cathode electrodes in each of which polarizable electrode layers are formed on and lead wires are fixed to both sides of a current collector made of metallic foil, such that the polarizable electrode layers are opposed to each other. Further, an electric double-layer capacitor is provided in which the lead wire is fixed to a polarizable-electrode-layer-removed section on the electrode where the polarizable electrode layer has been removed, and an area of the polarizable-electrode-layer-removed section is not smaller than 1 and not larger than 2.0 when a project area of a portion where the lead wire is connected with the current collector is set to 1.</p> |
