INDUSTRIAL APPLICATION FIELD The present invention relates to a small-sized, large-capacity electric double layer capacitor. Conventional configuration and its problems A typical configuration example of this type of capacitor will be described below. First, as shown in FIG. 1, an electrode material made by adding graphite, carbon black, tetrafluoroethylene, polyvinylpyrrolidone, etc. to activated carbon powder is used as a polarizable electrode 1, and a current collector 2 is used. A thin metal net or punching metal is used as a metal thin plate net or punching metal, and the polarizable electrode material is applied to the surface of this using a rolling roller or the like and dried and hardened to form a polarizable electrode body. An element is constructed by stacking the elements and winding them up through a wire, and an electrolytic solution is injected into the element. In such a configuration, the activated carbon particles may fall off from the current collector, the adhesive strength between the two may be insufficient, the contact resistance may be large, and the performance particularly during strong discharge may be poor. In addition, as another example, as shown in Figure 2,
Activated carbon fiber cloth is used as the polarizable electrode 4, and a metal layer such as aluminum or titanium or a conductive resin layer is formed on one side of the polarizable electrode 4 as the current collector 5 to form a polarizable electrode body. The polar electrode bodies are overlapped with each other via a separator 3 to form an element, and an electrolytic solution is injected into this element, and a gasket 6 is injected into the element.
The casing is constructed by sealing the coin-shaped case 7 and the sealing plate 8 in which the positive and negative electrodes are insulated. A device having such a configuration has sufficient current collection ability when used for charging and discharging with a current of 10 mA or less. However, the current collecting ability is not sufficient to repeatedly charge and discharge with a current of about 1 A, and the contact resistance is too large, making it impossible to efficiently extract the accumulated charge. As described above, in the current capacitor configuration, the contact resistance between the current collector and the case, the current collector and the polarizable electrode, or even between the current collector and the conductive layer is large, and the rapid charge/discharge characteristics and the strong It does not have sufficient characteristics for discharge. OBJECTS OF THE INVENTION The object of the present invention is to shorten the charging time of conventional electric double layer capacitors and to obtain a capacitor with improved strong discharge characteristics. Structure of the invention The present invention achieves the above objects,
A thread-like, woven fabric-like, or felt-like metal fiber is used as the current collector of the polarizable electrode, and this structure improves the current collecting ability of the capacitor and improves the charge/discharge characteristics. Description of Examples Before describing specific examples, the metal fibers used in the current collector of the present invention will be explained. For example, metal fibers can be made from round metal rods with a diameter of 5 to 50μ and a diameter of 1 to
It is cut into short fibers with a length of 10 mm. The short metal fibers having such a shape can be twisted together to form a thread, or further woven into a cloth, or the short fibers can be sintered to form a felt. Currently, cloth-like metal fibers are used as static electricity removers, heat-insulating materials, heat-resistant materials, and sound-absorbing and sound-deadening materials. This kind of material has the same appearance as ordinary fiber cloth and is extremely flexible. Example 1 An electric double layer capacitor shown in FIG. 3 was manufactured using the following materials. As a polarizable electrode, a satin woven fiber cloth made of phenolic novolac resin was carbonized and the specific surface area was
Activated carbon fiber cloth (satin weave) with an area of 2500 m 2 /g and a basis weight of 150 g/m 2 was used. Moreover, a porous separator made of polypropylene was used as a separator. As the current collectors, Nos. 1 to 6 in Table 1 were used, respectively. FIG. 4 shows the relationship between the polarizable electrode 4 and the current collector 5. The fiber cloth-like current collectors of Nos. 1 and 2 have a significantly larger contact surface with the fiber cloth-like polarizable electrode than conventional flat plates or etched foils, and can reduce contact resistance. Further, in Nos. 3 and 4, the felt-like metal fibers 9 penetrate into the inside of the polarizable electrode to improve current collection ability, as shown in FIG.

のキヤパシタは一段と集電能が改善されている。[Table] All current collectors are nickel. 20wt% potassium hydroxide KOH was used as the electrolyte. Nickel wire was welded to the current collector to form the lead. In the diagram of FIG. 3, 4 is a polarizable electrode, 5 is a current collector,
3 is a separator, 10 is a lead, 11 is an acrylic container, and 12 is packing. The size of the IR drop when the capacitors (polarizable electrode body, 100 x 50 mm 2 thickness 0.8) prepared using current collectors Nos. 1 to 6 were discharged at 200 mA were Nos. 1, 2, and 6. 3,
It can be seen that the capacitors are smaller in the order of No. 4, No. 5, and No. 6, and the current collecting ability of the capacitor of the present invention is better than that of the conventional capacitor No. 5 and No. 6. Further, FIG. 6 shows charging curves when capacitors using the current collectors Nos. 1 to 6 above were charged by a constant voltage charging method of 1.0 V. The figure clearly shows that the capacitor of the present invention has good current collecting ability. Note that the weaving methods of the metal fiber cloth of the current collector and the fiber cloth of the polarizable electrode body tend to exhibit better current collecting ability when combined with the same weaving method, such as plain weave-plain weave, satin weave-satin weave, etc. It was observed. Furthermore, the thinner the metal fiber, the more flexible it is and the higher its current collecting ability is. In this example, only a fiber cloth-like polarizable electrode is described, but similar current collection characteristics were obtained with a felt-like polarizable electrode. In this example, a current collector made of nickel was used, but even if the current collector material was changed to SUS444, a capacitor with similar characteristics could be obtained. Example 2 In order to further improve the current collecting ability than in Example 1, a 300 μm thick nickel layer was formed on the surface of a polarizable electrode made of activated carbon fibers in the form of fiber cloth or felt using a plasma spraying method. Here, the polarizable electrode and the current collector are welded together in multiple spots. A capacitor having the same structure as that shown in FIG. 3 was fabricated using the polarizable electrode with improved current collecting ability as described above. The current collectors listed in Table 1 Nos. 1 to 6 of Example 1 were used.
Table 2 shows the IR drop values when discharged with the same size and under the same conditions as in the example. From Table 2, the capacitor of the present invention has a much improved current collecting ability.

る。[Table] Example 3 A phenolic resin fiber cloth was activated and an activated carbon fiber cloth having a specific surface area of 2500 m 2 /g and a pore volume of 1 c.c./g was used as a polarizable electrode. A conductive layer having a thickness of 200 to 300 μm was formed using a thermal spraying method or an arc spraying method. A felt-like metal fiber (aluminum, 30 μφ) was used as a current collector, and the polarizable electrode was wrapped around it to form a capacitor as shown in FIG. 4 is a polarizable electrode, 13 is a conductive layer, 5 is a current collector, 3 is a separator, and 10 is a lead. A 1 mol propylene carbonate solution of terera ethylene ammonium perchlorate was used as the electrolyte. IR when a capacitor having the configuration of this example (electrodes: 150 x 100 mm 2 , thickness 800 μm) is charged at a constant current of 2V and discharged at a constant current of 500mA.
The drop was 0.3V, which is a relatively small value even though it is an organic electrolyte system and has a large internal resistance. Even if titanium is used for the conductive layer and the current collector, a capacitor having characteristics similar to those of this example can be obtained. Example 4 Although Example 3 is a flat capacitor, a large spiral-shaped capacitor was created in the same manner as Example 3. The conductive layer is formed only on one side of the polarizable electrode,
Place a felt-like metal fiber on the conductive layer side and
The polarizable electrode bodies were placed opposite to each other with a polypropylene separator of 2 mm in between, and wound as shown in FIG. 8 to create a capacitor. As a result, constant current discharge was possible at 1A. The electrodes were 50 x 300 mm2 in size. Therefore,
Even considering that the electrode area is large and the resistance is low, it can be seen that the current collecting ability is good. Effects of the Invention As described above, according to the present invention, it is possible to obtain an electric double layer capacitor that has a better current collecting ability than the conventional one.
