本発明は炭素繊維の表面に金属を被覆した炭素繊維強化
金属からなる基板用格子に金属を付着させたことを特徴
とするアルカリ蓄電池用電極板に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrode plate for an alkaline storage battery characterized in that a metal is attached to a substrate grid made of a carbon fiber reinforced metal in which the surface of carbon fibers is coated with metal.
近年、従来の石油自動車にかわるものとして排気ガスが
無く、騒音の低い電気自動車が注目されているが、その
実用化には耐久性に優れ、軽量で性能の高い蓄電池の開
発が急務である。In recent years, electric vehicles with no exhaust gas and low noise have been attracting attention as an alternative to conventional petroleum vehicles, but in order to put them into practical use, there is an urgent need to develop storage batteries that are durable, lightweight, and have high performance.
従来一般に使用されている鉛蓄電池は電極板として、比
重１１．３６の鉛製の格子に、活物質として見掛比重４
．５の過酸化鉛の粉末を充填したものを使用しているた
め重量が大で、しかも過酸化鉛は粒子間の結合力が弱い
ため崩壊が早期に始１す、充放電サイクルを繰返してい
るとしだいに性能が低下する欠点を有する。The conventionally commonly used lead-acid batteries have a lead grid with a specific gravity of 11.36 as the electrode plate, and a lead grid with an apparent specific gravity of 4 as the active material.
．． It is heavy because it is filled with lead peroxide powder (No. 5), and lead peroxide has a weak binding force between particles, so it begins to disintegrate early and requires repeated charging and discharging cycles. The disadvantage is that the performance gradually deteriorates.
したがって、鉛蓄電池は電気自動車の電源のように過酷
な充放電サイクルを繰返す用途には不向きである。Therefore, lead-acid batteries are unsuitable for applications that involve repeated severe charging and discharging cycles, such as power sources for electric vehicles.
一方、アルカリ蓄電池は耐久性に優れているバ電極板と
してニッケル、鉄などの基板を用いているため、電気容
量に対する重量比が鉛蓄電池に比べて特に優れていると
は言えない。On the other hand, since alkaline storage batteries use substrates made of nickel, iron, or the like as bar electrode plates that have excellent durability, it cannot be said that the weight ratio to electric capacity is particularly superior to that of lead-acid batteries.
本発明は、比重の小さい炭素繊維の表面に金属を被覆し
た炭素繊維強化金属を基板用格子とすることによって、
軽量で耐久性に優れた電極板を提供することを目的とす
るものである。The present invention uses carbon fiber reinforced metal, which is made by coating the surface of carbon fiber with a small specific gravity with metal, as a grid for the substrate.
The purpose is to provide an electrode plate that is lightweight and has excellent durability.

ced metal), in which the surface of carbon fibers is coated with metals such as nickel, aluminum, magnesium, etc. by methods such as electrodeposition, vapor deposition, powder metallurgy, thermal spraying, or vacuum infiltration. It has superior mechanical and electrical properties compared to carbon fiber alone.
以下、本発明の実施例を示す添付図面に基づいて説明す
る。DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.
第１，２図にむいて、１は炭素繊維強化金属２により織
製した基板用格子であって、炭素繊維強化金属２は直径
０．２〜０．５ｍｍの炭素繊維３の表面に数十ミクロン
の厚さの金属４が被覆されている。1 and 2, 1 is a substrate lattice woven from carbon fiber-reinforced metal 2, and the carbon fiber-reinforced metal 2 is attached to the surface of carbon fibers 3 having a diameter of 0.2 to 0.5 mm. A metal 4 of micron thickness is coated.
５はニッケル、カドニウムまたは鉄等の金属粉末であっ
て、通常のアルカリ蓄電池の電極板の製造に使用される
粉体焼結法または連続焼結法によって基板用格子１に付
着させられている。Reference numeral 5 is a metal powder such as nickel, cadmium or iron, which is adhered to the substrate grid 1 by a powder sintering method or a continuous sintering method used for manufacturing electrode plates of ordinary alkaline storage batteries.
６は基板用格子１に接続された端子である。6 is a terminal connected to the substrate grid 1.
第３図は本発明の第２実施例の基板用格子１ａを示し、
この格子は一本の炭素繊維単体属２ａにより構成されて
いて、その両端が端子６ａに接続されている。FIG. 3 shows a substrate grid 1a according to a second embodiment of the present invention,
This lattice is composed of one single carbon fiber element 2a, both ends of which are connected to terminals 6a.
本実施例の基板用格子１ａは、前記第１，２図例の基板
用格子１のように多数の炭素繊維強化金属が表面の接触
により電気的に接続しているのではなく、一本の炭素繊
維強化金属によって構成され、しかもその両端が端子に
接続しているから、格子内の電気抵抗が小さい利点があ
る。The substrate grid 1a of this embodiment does not have a large number of carbon fiber-reinforced metals electrically connected by surface contact, as in the substrate grid 1 shown in FIGS. Since it is constructed of carbon fiber reinforced metal and both ends are connected to terminals, it has the advantage of low electrical resistance within the grid.
上記のような構成になる本発明の電極板は、通常のアル
カリ蓄電池用電極板のように、真空含浸法または溶融含
浸法により活物質を含浸、析出させて使用される。The electrode plate of the present invention having the above structure is used by impregnating and precipitating an active material by a vacuum impregnation method or a melt impregnation method, like an ordinary electrode plate for an alkaline storage battery.
以上の説明によって明らかにしたように、う本発明の電

覆した炭素繊維強化金属によって基板用格子を構成した
から、金属板または金属網からなる従来のアルカリ蓄電
池用電極板に比べて重量を著しく軽減させることができ
る。As clarified by the above explanation, in the electrode plate of the present invention, the substrate lattice is made of carbon fiber-reinforced metal in which the surface of carbon fiber having a specific gravity of 2.27 or less is coated with metal. The weight can be significantly reduced compared to conventional electrode plates for alkaline storage batteries made of mesh.
渣た、本発明においては、炭素繊維単体ではなく炭素繊
維強化金属を用いて、被覆金属に金属を付着させるよう
にしたから、炭素繊維に金属を直接付着させる場合に比
べて結合力が強く、機械的強度が著しく高い。Furthermore, in the present invention, since the metal is attached to the coating metal using carbon fiber reinforced metal instead of carbon fiber alone, the bonding force is stronger than when the metal is attached directly to the carbon fiber. Mechanical strength is extremely high.
さらに、炭素繊維はアルカリに対する耐食性に優れてい
るとともに、アルカリ蓄電池においては原理上電極金属
自体１ｄ化学変化を生じないため、炭素繊維強化金属の
金属被覆を２０ミクロン以下にしても耐久性に問題はな
い。Furthermore, carbon fiber has excellent corrosion resistance against alkalis, and in principle, in alkaline storage batteries, the electrode metal itself does not undergo 1d chemical change, so even if the metal coating of carbon fiber reinforced metal is 20 microns or less, there is no problem with durability. do not have.
したがって、電極板の厚さを１闘以下にすることが可能
であり、電極板を薄くすることによって、一定容積内の
収容枚数を増加させて電気的容量を増大させることがで
きる。Therefore, it is possible to reduce the thickness of the electrode plate to 1 mm or less, and by making the electrode plate thinner, the number of electrode plates accommodated within a certain volume can be increased and the electrical capacity can be increased.
このように、本発明の電極板はアルカリ蓄電池の耐久性

のような効果をあげることはできない。Although unrelated to the present invention, even if a substrate lattice made of carbon fiber reinforced metal is used as an electrode plate for a lead-acid battery, the active material may be eroded by the electrolyte, or Pbo24+Pb5o4, pbePb due to charge/discharge cycles. Since chemical changes such as So 4 occur in the lattice 1, it is not possible to achieve the same effect as the present invention in terms of durability.
