    • An electric double layer capacitor having an electrode rolled body contained in an outer packaging can. The electrode rolled body includes a positive electrode plate having a positive electrode foil, on both sides of which an active substance is applied, a negative electrode plate having a negative electrode foil, on both sides of which the active substance is applied, and a separator interposed between these electrode plates, and is obtained by winding the above parts. The negative electrode foil is electrically connected directly to a bottom of the outer packaging can so that heat generated in an interior of the electric double layer capacitor is efficiently transferred to the outer packaging can from the negative electode foil. The negative electrode foil has a greater thickness than that of the positive electrode foil, which is not electrically connected to the outer packaging can, so that heat quantity transferred is made large.
    • 具有包含在外包装罐中的电极卷绕体的双电层电容器。 电极卷绕体包括具有正极箔的正极板,其两侧涂有活性物质,具有负极箔的负极板,其两侧涂有活性物质,隔板 插入在这些电极板之间,并通过卷绕上述部件获得。 负极箔直接电连接到外包装罐的底部,使得在双电层电容器的内部产生的热量从负电极箔有效地传递到外包装罐。 负极箔的厚度比不与外包装体电连接的正极箔的厚度大,所以传递的热量大。

    • An electric double-layer capacitor includes a plurality of electrode elements each having a current collector, a polarized electrode disposed on a surface thereof, and a strip-like current collecting lead extending from an end of the current collector. The electrode elements are stacked as alternately belonging to respective polarities, and the current collecting leads of the electrode elements are stacked into lead assemblies of the respective polarities. A separator is interposed between the stacked electrode elements, and the lead assemblies are connected respectively to electrode terminals. The lead assemblies of respective polarities serve as respective connectors connected to the electrode terminals. Each of the connectors has a flat joint region as at least a portion thereof. The current collecting leads of each of the lead assemblies are integrally joined to each other by the flat joint region by ultrasonic welding before the connector is connected to the electrode terminal. The connectors are joined to the electrode terminals, respectively, through the respective joint region by electron beam welding or laser beam welding.
    • 电双层电容器包括多个电极元件,每个电极元件均具有集电器,设置在其表面上的极化电极和从集电器的端部延伸的带状集电引线。 电极元件交替地堆叠成各自的极性,并且电极元件的集电引线被堆叠成各极性的引线组件。 在堆叠的电极元件之间插入隔板,并且引线组件分别连接到电极端子。 各极性的引线组件用作连接到电极端子的相应连接器。 每个连接器具有至少一部分的平坦接合区域。 在连接器连接到电极端子之前,每个引线组件的集流引线通过超声波焊接通过平坦接合区域彼此一体地接合。 连接器分别通过电子束焊接或激光束焊接通过相应的接合区域连接到电极端子。
