＼ Large-capacity capacitors that utilize the electric double layer capacitance accumulated in the interfacial electric double layer between activated carbon and electrolyte. Conventionally, there are two types of electric double layer capacitors: sulfuric acid. One uses an aqueous electrolyte such as an aqueous solution or a liquid, and the other uses an organic solvent electrolyte in which an electrolyte is added to an organic solvent such as propylene carbonate. This shows the configuration of a typical example. As shown in Figure 3
An activated carbon powder electrode 22 is made up of an insulating rubber case 23 and a conductive electrode 25, facing each other with a separator 2I in between.

る。Problems to be Solved by the Invention The two conventional electrolyte-based capacitors each have the following characteristics (advantages and disadvantages). The advantage of an aqueous solution system is that the electrical resistance of the electrolyte is low and it is suitable for large current load discharge.The disadvantage is that the withstand voltage of the capacitor depends on the decomposition voltage of the electrolyte, but it can only be obtained up to 1.0V. That's true. When used at high voltages, many capacitors must be connected in series, which poses problems in terms of long-term use and reliability.

パシタおよびその製造方法を得ることを目的とする。On the other hand, the advantage of organic solvent systems is that the electrolyte has a high withstand voltage (~3V
), it is possible to use higher voltages than aqueous solutions. Disadvantages: Due to the electrical resistance of the electrolyte, the internal resistance of the capacitor is 5 to 10 times higher than that of an aqueous solution system, making it difficult to use in applications with large current loads.Furthermore, in the above two systems, activated carbon The purpose of the present invention is to directly manufacture electrodes from a paste containing powder.It is difficult to manufacture large-area electrodes with uniform film thickness, and it has been impossible to realize large capacitors with excellent quality. In addition to realizing a capacitor that combines the advantages of the two types of electrolyte capacitors, it also facilitates the production of large-area electrodes with uniform film thickness. That is, the object of the present invention is to obtain a large electric double layer capacitor having a high usable withstand voltage and a low internal resistance, and a method for manufacturing the same.
