Abstract

PURPOSE:To decrease the cost of a capacitior by forming a part for covering the electrode layer of a current collecting electrode higher than a part covering the edge of a sealing material, reducing pressure required for lamination and compression, and using a low-rigidity material for a case. CONSTITUTION:In a current collecting electrode 1, a part for covering an electrode layer 3 is formed so that the part is heaped up and it is higher than a part covering the edge of a sealing material 2. When the device is formed in this way, pressure when lamination and compression are performed is applied on the electrode layer 3 through the electrode 1 comprising a conductive rubber sheet and is not applied on the material 2. Therefore, the large pressure is not required for compressing the material 2, and the required pressure can be applied. Thus, the pressure which is required in compression is made small. A case having low rigidity can be used for laminating and containing cells. Thus the cost can be decreased.

とするものである。(Problem) However, in the cell C of the conventional structure described above, when stacking and applying pressure, if the sealing material 2 is not compressed, the electrode layer 3
There was a problem in that it was not possible to apply pressure to the metal, and a large amount of pressure was required. (Description of Problem) In the conventional cell C, the electrode layer 3 is filled up to the same height as the edge of the sealing material 2, and the current collecting electrode 1 is placed on top of the electrode layer 3. Therefore, when applying the pressure F as shown in FIG. 4, the pressure cannot be applied to the electrode layer 3 unless the sealing material 2 is compressed. However, the resistance force (reaction force) of the sealing material 2 against compression is large, and a large force is required as the pressure F. The need for large pressure itself is undesirable in terms of manufacturing operations. Further, it is necessary to store the device in the case 5 while applying such a large pressure, and for this purpose, the case 5 must be a strong and rigid case. As a result, the weight and cost increase. The present invention aims to solve the above problems! ! This is the subject.

FIG. 1 shows a cell of an electric double layer capacitor of the present invention, and the symbols correspond to those in FIG. 3. The difference in structure from the conventional cell shown in FIG. 3 is that the electrode layer 3 is filled so that the surface thereof is higher than the edge of the sealing material 2. L represents the height from the green of the sealing material 2 to the surface of the electrode layer 3. The current collecting electrode 1 may have a shape in which the portion covering the electrode layer 3 is raised by an amount L from the portion covering the edge of the sealing material 2, as shown in FIG. The reason why the electrode layer 3 is filled so that the surface is higher than the edge of the sealing material 2 as described above is to avoid receiving a reaction force from the sealing material 2 when stacking and applying pressure F. Figure 2 shows how the cell of the electric double layer capacitor of the present invention is pressurized.Since the electrode 1 is a conductive rubber sheet, when pressure F is applied from above, the sealing material 2 becomes lower. It does not touch the surface of the electrode layer 3, but covers the higher part of the electrode layer 3. Therefore, the required pressure can be applied without expending a large amount of pressure to compress the sealing material 2. Therefore, the value of pressure F is significantly reduced compared to the conventional case. Several stacked cells C are housed in a case with the pressure applied by caulking the edge of the case, but if the pressure F can be small as mentioned above, it will be used. The case should be of low rigidity.
