【0002】 [0002]

【従来の技術】図4は従来の電気二重層コンデンサの一例の断面図を示したものである。 BACKGROUND OF THE INVENTION FIG. 4 shows a sectional view of an example of a conventional electric double layer capacitor. この電気二重層コンデンサでは、イオン透過性及び非電子伝導性を有する多孔質のセパレータ1の両側に多数の活性炭粒子(電極)と電解質溶液とからなる分極性電極2、3が設けられ、その両側に非イオン透過性及び電子伝導性を有する集電電極4、5が設けられ、セパレータ1の両面の各周囲と集電電極4、5との間に絶縁ゴム等からなる枠状のガスケット6、7が設けられた構造となっている。 In the electric double layer capacitor, polarizable electrodes 2 and 3 consisting of a large number of activated carbon particles on both sides of the separator 1 of porous and (electrode) and the electrolyte solution with ion permeability and non-electronic conductivity is provided on both sides collector electrode 4, 5 is provided, a frame-shaped gasket 6 made of insulating rubber or the like between the respective surrounding surfaces of the separator 1 collector electrode 4, 5 having a non-ionic permeability and electron conductivity, 7 has become a provided structure. この場合、 in this case,
分極性電極2、3の電極として活性炭粒子を用いているのは、粒子径が10〜50μm程度とかなり小さいので、活性炭粒子群の単位体積当たりの表面積を大きくすることができ、ひいてはエネルギー密度を大きくすることができるからである。 What using activated carbon particles as an electrode of the polarizable electrodes 2 and 3, since the particle size considerably smaller, about 10 to 50 [mu] m, it is possible to increase the surface area per unit volume of the activated carbon particles, and hence energy density This is because it is possible to increase.

【0003】 [0003]

【発明が解決しようとする課題】しかしながら、従来のこのような電気二重層コンデンサでは、活性炭粒子径が10〜50μm程度とかなり小さいとはいっても、活性炭粒子群の単位体積当たりの表面積に限界があるので、 [0007] However, in such a conventional electric double layer capacitor, even if the diameter activated carbon particles is considerably smaller as about 10 to 50 [mu] m, a limit to the surface area per unit volume of the group of activated carbon particles because there,
エネルギー密度にも限界があるという問題があった。 In energy density there is a problem that there is a limit. この発明の課題は、分極性電極の電極の単位体積当たりの表面積をより一層大きくすることである。 Object of the present invention is to further increase more surface area per unit volume of the electrode of the polarizable electrodes.

【0004】 [0004]

【課題を解決するための手段】この発明は、分極性電極の電極として多数の微小な導電性チューブを用いたものである。 SUMMARY OF THE INVENTION The present invention using a large number of fine conductive tubes as electrodes of the polarizable electrode. 請求項4記載の発明は、導電性チューブとして外径1〜500nm程度のチューブ状炭素繊維を用いたものである。 Invention according to claim 4, in which using a tubular carbon fiber outer diameter of about 1~500nm as a conductive tube.

【0005】この発明によれば、分極性電極の電極として微小な導電性チューブを用いているので、導電性チューブ群の単位体積当たりの表面積を分極性電極の電極として活性炭粒子を用いる場合よりもより一層大きくすることができる。 [0005] According to the present invention, because of the use of fine conductive tubes as electrodes polarizable electrode, than the case of using activated carbon particles the surface area per unit volume of the conductive tube group as an electrode of the polarizable electrodes more can be further increased.

【発明の実施の形態】図1(A)はこの発明の第1実施形態における電気二重層コンデンサの断面図を示し、図1(B)はその模式的拡大断面図を示したものである。 PREFERRED EMBODIMENTS FIG. 1 (A) is a cross-sectional view of an electric double layer capacitor according to the first embodiment of the present invention, FIG. 1 (B) illustrates the schematic enlarged cross-sectional view.
この電気二重層コンデンサでは、セパレータ11の両側に分極性電極12、13が設けられ、その両側に集電電極14、15が設けられ、セパレータ11の両面の各周囲と集電電極14、15との間に枠状のガスケット1 In this electric double layer capacitor, both sides polarizable electrodes 12 and 13 provided in the separator 11, collector electrodes 14, 15 are provided on both sides, and both sides each surrounding and collector electrodes 14, 15 of the separator 11 gasket 1 of the frame between the
6、17が設けられた構造となっている。 6, 17 has become a provided structure. このうち分極性電極12、13は、多数の微小なチューブ状炭素繊維(導電性チューブ)18と電解質溶液19とからなっている。 Among polarizable electrodes 12 and 13 is made from a number of minute tubular carbon fiber (conductive tube) 18 electrolyte solution 19.. この場合、チューブ状炭素繊維18は、カーボンナノチューブと呼ばれるものからなっている。 In this case, tubular carbon fiber 18 is comprised of what are called carbon nanotubes. なお、セパレータ11は、両側の分極性電極12、13におけるチューブ状炭素繊維18同士が直接接触する虞がない場合は、省略することができる。 Incidentally, the separator 11, if there is no possibility that the tubular carbon fiber 18 to each other on both sides of the polarizable electrodes 12 and 13 are in direct contact can be omitted.

【0007】ここで、カーボンナノチューブと呼ばれるチューブ状炭素繊維18の形成方法について説明する。 [0007] Here, a method for forming a tube-like carbon fiber 18 called carbon nanotubes.
例えば、100〜500Torr程度のHeやAr等の不活性ガスを封入したガラス容器内において、ガラス容器内に配置された2本の炭素棒電極間に直流アーク放電を生じさせることにより、負極の炭素棒電極の表面に炭素堆積物を成長させ、この成長した炭素堆積物を掻き集めると、チューブ状炭素繊維18が得られる。 For example, in a glass container filled with inert gas as He or Ar or the like of about 100~500Torr, by generating a direct current arc discharge between carbon rod electrodes of the two placed in a glass container, the negative electrode carbon grown carbon deposits on the surface of the rod electrode, the raking the carbon deposits grown, tubular carbon fiber 18 is obtained. このようにして得られたチューブ状炭素繊維18の外径は1〜5 The outer diameter of the tubular carbon fiber 18 thus obtained 1-5
00nm程度であり、長さは0.05〜500μm程度である。 Is about 00nm, length is about 0.05~500μm. このチューブ状炭素繊維18を組み込む方法としては、チューブ状炭素繊維18と電解質溶液19とを混合してなるペーストをセパレータ11や集電電極1 As a method of incorporating the tubular carbon fiber 18, paste separator 11 made by mixing a tubular carbon fiber 18 and electrolyte solution 19 and the collector electrode 1
4、15に塗布する方法がある。 4 and 15 there is a method to be applied to.

【0008】このように、分極性電極12、13の電極として用いるチューブ状炭素繊維18の外径は1〜50 [0008] Thus, the outer diameter of the tubular carbon fiber 18 is used as an electrode of the polarizable electrodes 12 and 13 to 50
0nm程度であり、長さは0.05〜500μm程度であるので、チューブ状炭素繊維18群の単位体積当たりの表面積を分極性電極の電極として活性炭粒子を用いる場合よりもより一層大きくすることができ、ひいてはエネルギー密度をより一層大きくすることができる。 Is about 0 nm, the length is about 0.05 to 500 [mu] m, be further increased more than when using activated carbon particles the surface area per unit volume of the tubular carbon fiber 18 group as an electrode of the polarizable electrodes it can, can be further increased more and hence energy density. この場合、チューブ状炭素繊維18群の単位体積当たりの表面積をより大きくするには、チューブ状炭素繊維18の外径はなるべく小さい方が好ましく、例えば1〜100 In this case, to increase the surface area per unit volume of the tubular carbon fiber 18 groups, the outer diameter of the tubular carbon fiber 18 is preferably as small as possible, for example, 1 to 100
nm程度が好ましい。 About nm is preferable. ところで、チューブ状炭素繊維1 Incidentally, tubular carbon fiber 1
8は文字通りチューブ状であるので、その外周面のみならずその内周面も、電極表面として機能可能である。 Since 8 is literally tubular, the inner peripheral surface thereof not the outer peripheral surface thereof but also can be function as an electrode surface. 一方、チューブ状炭素繊維18がつぶれたりすることを考慮すると、チューブ状炭素繊維18が長すぎるのはあまり好ましくない。 On the other hand, considering that the tubular carbon fiber 18 is squashed, are less preferred for tubular carbon fiber 18 is too long. このため、チューブ状炭素繊維18の長さは例えば0.05〜10μm程度が好ましい。 Therefore, the length of the tubular carbon fiber 18 is, for example, about 0.05~10μm are preferred.

【0009】ここで、この電気二重層コンデンサの充電状態の場合について図1(B)を参照して簡単に説明する。 [0009] Here, it described briefly with reference to FIG. 1 (B) for the case of the state of charge of the electric double layer capacitor. 集電電極14を負極とし、集電電極15を正極として充電を行うと、両電解質溶液19、22中のプラスイオンが負極側の分極性電極12のチューブ状炭素繊維1 The collector electrode 14 and the negative electrode is charged a collecting electrode 15 as a positive electrode, a tubular carbon fiber 1 of both electrolyte solution plus ions in 19 and 22 on the negative electrode side polarizable electrode 12
8の表面に吸着され、両電解質溶液19、22中のマイナスイオンが正極側の分極性電極13のチューブ状炭素繊維18の表面に吸着されることになる。 Adsorbed to 8 surface, so that the negative ions in both the electrolyte solution 19, 22 is adsorbed to the surface of the tubular carbon fiber 18 on the positive electrode side of the polarizable electrode 13.
