ものである。Conventional structure and its problems The basic structure of an electric double layer capacitor using activated carbon as a polarizable electrode is as shown in FIG. An electrolytic solution is impregnated between a pair of polarizable electrodes, and a separator is used to prevent a short circuit.
従来、この種の電気二重層キャパシタの構成例としては
、次の3種のものがあシ、これらの構成と問題点を概説
する。Conventionally, there are the following three types of configurations of this type of electric double layer capacitor, and their configurations and problems will be summarized.

抵抗が次第に増大したシ、活性炭電極層の利用効率が次
第に低下する等の欠点があった。The first one uses a punched aluminum metal as the current collector 4, as shown in FIG. Form-press the polarizable electrode material or
Alternatively, it is supported by a rolling roller, a pair of current collectors and polarizable electrodes are wound around the separator 3, and an electrolytic solution is injected. The activated carbon powder used here is generally 1
It is difficult to have a specific surface area of oooonX7y or more. In such a polarizable electrode, the amount of activated carbon per unit volume is reduced by the fluororesin or the like, and the double layer capacity is also reduced. Furthermore, in the polarizable electrode manufactured using the above-mentioned current collector, the metal current collector and the activated carbon electrode are basically only in physical contact;
In particular, when a polarizable electrode is spirally wound to form a spiral structure, the activated carbon electrode layer on the outside of the current collector and the activated carbon electrode layer on the inside of the current collector have opposite stresses, so the current collector and activated carbon electrode There were disadvantages such as the contact became weaker, the internal resistance of the electric double layer capacitor gradually increased, and the utilization efficiency of the activated carbon electrode layer gradually decreased.

に構成できる。As shown in FIG. 3, the second electrode is a polarizable electrode 6 made of cloth 9 mainly composed of activated carbon fibers, such as paper or felt, and a metal layer 6 made of aluminum or titanium as a current collector 6. The pair of polarizable electrodes can be constructed by a thermal spraying method, vapor deposition method, etc., and after injecting an electrolytic solution, the pair of polarizable electrodes can be constructed into a coin shape with an exterior case 7 and a gasket 8 via a separator 3.

なる。In addition, this kind of device has a polarizable electrode 5 having a metal layer 6.
This is an advantageous method in which activated carbon fibers can be wound into a superstructure and configured into any desired shape, such as having the configuration described in the first configuration, and activated carbon fibers have sufficient strength during processing. Unlike the case where a binder is used, a binder is not required, and therefore the capacity per unit volume is also increased.
しかしながら、この方法の欠点は、活性炭繊維が高価で

抗を小さくすることが極めて困難なのが現状である。し
たがって放電時に大電流を取り出すことができないとい
う欠点を有する。However, the disadvantage of this method is that the activated carbon fibers are expensive and the fiber diameter is as small as about 3 to 12 mφ, so it is currently extremely difficult to reduce the electrical resistance. Therefore, it has the disadvantage that a large current cannot be extracted during discharge.

ある。The third method is to activate carbonize glassy carbon and use it for polarizable electrodes. However, this method makes it difficult to synthesize glassy carbon, and it is still difficult to obtain a material with a large specific surface area even after activated carbonization. Furthermore, the first.
It is also extremely difficult to process into the configuration mentioned in 2.

実施例の説明
具体的実施例を述べる前に本発明の活性炭化した多孔体
について述べる。Description of Examples Before describing specific examples, the activated carbonized porous body of the present invention will be described.
本発明の分極性電極に用いる活性炭多孔体の製造法につ
いて最初に述べる。活性炭多孔体を作製するためには、
まずフェノール樹脂の多孔体を作製しなければならない
、一般にフェノール・ホルムアルデヒド樹脂にはノボラ
ック樹脂とレゾール樹脂が知られている。ノボラック樹
脂は、通常フェノール対ホルムアルデヒドのモル比、例

ホルマリンとを反応させて製造されるもので、ノボラッ
ク樹脂は、フェノールが主としてメチレン基によって結
合された3〜5量体が主成分をなし、遊離メチロール基
をほとんど含有していない。First, a method for manufacturing the activated carbon porous body used in the polarizable electrode of the present invention will be described. In order to make an activated carbon porous body,
First, a porous body of phenol resin must be prepared. Generally, novolac resins and resol resins are known as phenol formaldehyde resins. Novolac resins are produced by reacting phenol and formalin using an acid catalyst such as oxalic acid under conditions in which there is an excess of phenol, such that the molar ratio of phenol to formaldehyde is, for example, 0.7 to 0.9. The novolac resin is mainly composed of trimers to pentamers of phenol bonded mainly through methylene groups, and contains almost no free methylol groups.
従ってそれ自体は自己架橋性を有せず、熱可塑性を有す
る。まだ、この種のノボラック樹脂の他に。Therefore, it itself does not have self-crosslinking properties and has thermoplasticity. Yet, besides this kind of novolak resin.
フェノール基が7〜10個スチレン基で結合された比較
的高縮合体の硬化ノボラック樹脂は本発明の材料に用い

明の原料に適する。The resol resin is a highly reactive resin whose main component is a phenol compound having a relatively large amount of methylol groups. These phenolic resins are suitable as raw materials for the present invention.
さらに、従来のフェノール樹脂硬化物は、三次元架橋密

最適になるようにコントロールした(ネット・7−クポ

本発明原料として最適である。Furthermore, conventional cured phenolic resins have an excessively high three-dimensional crosslinking density, making them harder and more brittle than necessary. Therefore, the crosslinking density was controlled to be sufficient and optimal for the development of the properties of the cured phenolic resin (the network of the net 7-copolymer is large), and it has "stretchability" and "stickiness" compared to the cured product of the resol resin. Those with excellent properties are most suitable as raw materials for the present invention.
次に、活性炭多孔体の製造法について、−例を上げて述
べる。Next, a method for producing an activated carbon porous body will be described by giving an example.
多孔体のフェノール樹脂を作製するには、ポリビニルア
ルコール(ポバール)のホルマール化反応を利用する。To produce porous phenolic resin, a formalization reaction of polyvinyl alcohol (poval) is used.

(2)混合液にホルマリンおよび反応触碌の硫酸を加え

の気泡を含んだ状態の反応液を型に流し込む。(2) Add formalin and sulfuric acid as a reaction catalyst to the mixed solution, stir thoroughly, and pour the reaction solution containing many bubbles into a mold at the initial stage of the formalization reaction.
(3)室温ないし50°Cで10〜40時間反応させる
とホルマール化度60〜70%の水に不溶性の発泡体が
生ずる。(3) When reacted for 10 to 40 hours at room temperature to 50°C, a water-insoluble foam having a degree of formalization of 60 to 70% is produced.
(4) フェノール樹脂を熱融着させるために、150

Heat to ~180°C.
(5)生成発泡体を十分水洗して、でん粉および酸を完
全に除去すれば、連続気泡を持ったフェノール樹脂多孔

によって変化する。The number, size, etc. of bubbles in the porous body vary depending on the mass of the pore agent, the viscosity of the formalin additive mixture, the reaction conditions, and the degree of formalization.

られる。First, carbonization proceeds by applying a temperature of 800 to 1000° C. to the above-mentioned material in an inert gas atmosphere such as nitrogen gas or in a vacuum. When conventional phenolic resins are carbonized, they become extremely brittle, but when the resin and porous body manufacturing method of the present invention is used, mechanical strength not found in conventional products can be obtained.

Although it is possible to activate the carbonized material to make it activated carbon, it is more efficient to carbonize and activate the activated carbon porous body with good properties. For activation, the phenolic resin porous body is heated at 800 to 1000°C in a nitrogen and water vapor atmosphere. ■After treating the porous material with a catalyst such as sodium hydroxide or zinc chloride, SOO under nitrogen atmosphere or nitrogen or oxygen atmosphere

In Example 1, a conductive resin having carbon particles as conductive particles was used for the conductive electrode, but in this example, aluminum was formed on the surface of the activated carbon porous body by plasma spraying. When the plasma spraying method is used, the bond between the activated carbon porous body and aluminum becomes strong and the contact resistance can be reduced, and since the electrode is an aluminum metal conductive electrode, the conductivity is better than that of Example 1.
