充電は現段階ではできない状態である。Conventional configurations and their problems Conventionally, high energy density batteries using lithium as the active material for the negative electrode, so-called lithium batteries, have used a mixture of fluorocarbon and carbon blank, or manganese dioxide and carbon blank, or manganese dioxide and carbon blank for the positive electrode. Using a mixture with a binder, lithium metal is used as the negative electrode, propylene carbonate or γ-7"f rolactone in which lithium perchlorate or lithium borofluoride is dissolved in the electrolyte, or these and 1,2 dimethoxyethane (hereinafter referred to as DME) are used. However, in the case of this system, it is used as a primary battery;
Charging is currently not possible.

ート、！：ＤＭＥ３　、 との混合液を用いたものが発表されている。On the other hand, rechargeable DC power batteries include batteries that use activated carbon fiber as the positive and negative electrodes and propylene carbonate in which ammonium perchlorate is dissolved as the electrolyte, or batteries that use activated carbon fiber as the positive electrode and lithium metal as the negative electrode. , propylene carbonate with lithium perchlorate dissolved in the electrolyte,! : DME3 and a mixture using these have been announced.

これらは、電気二重層における電荷チャージを主にした
ものであるが、電池としての電気容量あるいは充放電サ
イクル寿命が必ずしも充分ではなく、そのもののもつ電
気抵抗が高いことなどから内部抵抗も高い。Although these batteries are mainly charged with electric charges in the electric double layer, they do not necessarily have sufficient electrical capacity or charge/discharge cycle life as batteries, and their internal resistance is also high due to their high electrical resistance.

その理由としては、用いている活性炭素繊維の材質が十
分ではないからである。The reason for this is that the quality of the activated carbon fiber used is not sufficient.

従来、検討されている活性炭素繊維はセルロースを原料
としたものであり、通常用いられるグレードの比表面積
は最高でも、１０００ｍ２／ｇ以下であるし、灰分も非
常に大きく、カーボンブラックなどに較べて純度が著し
く低いものである。The activated carbon fibers that have been considered so far are made from cellulose, and the specific surface area of the commonly used grades is at most 1000 m2/g or less, and the ash content is also very high, compared to carbon black etc. The purity is extremely low.

さらに、比表面積も均一ではなく、バラツキが大きい。Furthermore, the specific surface area is not uniform and has large variations.

これらのことから、いままでの活性炭素繊維では電池の
内部抵抗や電気容量、あるいは充放電サイクル寿命々ど
の特性を向上させることが困難であり、活性炭素繊維の
改良が必要とされていた。For these reasons, it has been difficult to improve the internal resistance, electric capacity, charge/discharge cycle life, and other characteristics of batteries using conventional activated carbon fibers, and there has been a need for improvements in activated carbon fibers.

発明の目的 本発明は、リチウム金属を負極に用いた充電可能な電池
において、正極を構成する活性炭素繊維を改良すること
により、電気容量が大きく、シかも充放電サイクル寿命
を向上させることを目的としたものである。Purpose of the Invention The purpose of the present invention is to improve the activated carbon fiber that constitutes the positive electrode in a rechargeable battery using lithium metal as the negative electrode, thereby increasing the electric capacity and the charge/discharge cycle life. That is.

発明の構成 本発明は、上記の目的を達成するため、活性炭素繊維の
改良探索を行なったところ、つぎの活性炭素繊維がこの
電池系においてすぐれた効果を示すことを見いだした。Structure of the Invention In order to achieve the above object, the present invention searched for improvements in activated carbon fibers and found that the following activated carbon fibers exhibit excellent effects in this battery system.

すなわち、リチウム金属を負極とし、有機電解液を用い
る充電可能な電池の正極として、フェノール系樹脂より
得られた活性炭素繊維を主体としたことを特徴とするも
のである。That is, it is characterized in that the positive electrode of a rechargeable battery using lithium metal as a negative electrode and an organic electrolyte is mainly made of activated carbon fiber obtained from a phenolic resin.

フェノール系樹脂繊維はその純度が高く、比表面積も大
きい。しかも均一性にもすぐれるので、これより得た活
性炭素繊維は同じように純度が高いとともに、比表面積
も大きく、織布又は不織布のシート状にしても比表面積
の均一なものができる。Phenolic resin fibers have high purity and a large specific surface area. In addition, since it has excellent uniformity, the activated carbon fiber obtained from it has high purity and a large specific surface area, and even when it is made into a sheet of woven or nonwoven fabric, it can have a uniform specific surface area.

５べ〕 たとえば、本発明における活性炭素繊維の特徴を従来の
活性炭素繊維と比較すると第１表の如くなる。5] For example, Table 1 shows the characteristics of the activated carbon fiber according to the present invention when compared with conventional activated carbon fiber.

（第　１　表） これから明らかなように、本発明の活性炭素繊維は従来
よりも比表面積がはるかに大きく、シかも比表面積を任
意に選択することができる。また純度も灰分よシみて従
来品よりはるかにすぐれている。(Table 1) As is clear from this, the activated carbon fiber of the present invention has a much larger specific surface area than the conventional one, and the specific surface area can be arbitrarily selected. In addition, the purity is far superior to conventional products in terms of ash content.

本発明における活性炭素繊維の好ましい細孔半径は１０
〜６０への範囲である。活性炭素繊維の細孔半径が１０
八よりも小であると電解液の浸透が困難となり、電気容
量が減少する。一方逆に６、、、ノ ６０人よりも大であると比表面積が減少し、電子伝導性
が悪化して好ましくない。The preferred pore radius of the activated carbon fiber in the present invention is 10
to 60. The pore radius of activated carbon fiber is 10
If it is smaller than 8, it will be difficult for the electrolyte to penetrate and the capacitance will decrease. On the other hand, if it is larger than 60, the specific surface area decreases and electron conductivity deteriorates, which is not preferable.

この活性炭素繊維は結着剤で混合し、シート成型をする
ことができるが、結着剤を含まずにそれ自体で織布又は
不織布のシート状に成形することができ、使い易さとし
ては布状の方が便利である。This activated carbon fiber can be mixed with a binder and molded into a sheet, but it can also be molded into a woven or non-woven sheet by itself without a binder, and is easy to use. Cloth is more convenient.

また、この活性炭素繊維を正極として用いる場合、その
片面に集電体をラミネートするか、あるいは一体化して
用いるが、集電体材料としては、アルミニウム、チタン
などのラス、スクリーン。In addition, when this activated carbon fiber is used as a positive electrode, a current collector is laminated on one side of the fiber or is used in an integrated manner.As the current collector material, a lath or a screen made of aluminum, titanium, etc. can be used.

パンチングメタルを用いることができる。Punched metal can be used.

さらによい手段としては、活性炭素繊維の片面に均一か
つ強固に集電体部材が付着することの可能な金属粉末の
溶射がすぐれている。An even better method is thermal spraying of metal powder, which can uniformly and firmly adhere the current collector member to one side of the activated carbon fibers.

こうすることにより一体化する集電体に起因して集電効
果が向上するばかりでなく、活性炭素繊維の強力な補強
材ともなり、充放電サイクル寿命の向上が期待できる。This not only improves the current collection effect due to the integrated current collector, but also serves as a strong reinforcing material for the activated carbon fibers, and is expected to improve the charge/discharge cycle life.
