した電気二重層コンデンサに関するものである。[Detailed description of the invention] [Field of industrial application] This invention relates to an electric double layer capacitor in which a plurality of electric double layer capacitor single cells are housed in an exterior case. This relates to an electric double layer capacitor in which single cells are combined and connected to obtain the following.
一般に、電気二重層コンデンサは、外装ケース

Generally, electric double layer capacitors are constructed by stacking multiple single cells in series within an exterior case, and their withstand voltage increases in proportion to the number of stacked single cells, but on the other hand, the capacitance increases. It decreases in proportion to the reciprocal.
そこで、特開昭61−135108号においては単一の

組合わされ、必要とする電圧、容量が得られる。 Therefore, in JP-A No. 61-135108, in order to be able to freely select the voltage and capacity with a single structure, a drawer was installed between the single cells housed in series in the outer case. An electrode is interposed therebetween, and a lead terminal electrically connected to the lead electrode is drawn out to the outside of the exterior case. In other words, the lead terminals at both ends of the laminated single cell and the lead terminals of the extraction electrodes interposed between the single cells are drawn out from the exterior case, and by selecting the lead terminals to be used, a predetermined single cell can be selected. are combined in parallel to obtain the required voltage and capacity.

However, according to this conventional example, when six single cells are stacked, for example, it is necessary to newly incorporate the same number of lead terminals as five extraction electrodes into the outer case, and this also requires the addition of lead terminals at both ends of the single cell stack. If two external terminals are added, there will be as many as seven external terminals, which will make the structure extremely complicated, which is unfavorable not only in terms of productivity but also in terms of practicality. Furthermore, when lowering the voltage and increasing the capacity, some of the six single cells may be omitted, resulting in poor cost performance (effect-to-cost ratio).

An object of the present invention is to provide an electric double layer capacitor that can achieve the following.
