本発明はニッケルー亜鉛蓄電池、銀−亜鉛蓄電池などに
用いられるアルカリ蓄電池用亜鉛極の製法に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION K) Field of industrial application The present invention relates to a method for producing zinc electrodes for alkaline storage batteries used in nickel-zinc storage batteries, silver-zinc storage batteries, and the like.
（ロ）従来の技術
近年著しく普及してきたボータプル電子機器の駆動電源
として＃電池の需要が急増している。(b) Prior Art The demand for #batteries is rapidly increasing as a power source for driving electronic devices that have become extremely popular in recent years.
その中でもアルカリ亜鉛蓄電池に負極活物質として用い

電位を示すことから、成泡として作動させた特高１圧が
収り出せ、且つ経蒼性や安全性が優れているなどの利点
【有する。Among them, zinc, which is used as a negative electrode active material in alkaline zinc storage batteries, has a high energy density per unit weight and exhibits a base potential. It has advantages such as excellent safety and safety.
ところが、アルカリ亜鉛蓄電池は光放ｔ’ｉ繰り返すと

が存在すると、この巨大粒子が核となり亜鉛のデンドラ
イトが生長し正負極間の短絡現象が生じる等の欠点があ
る。However, in an alkaline zinc storage battery, when light is emitted repeatedly, the zinc particles forming the negative electrode active material gradually become larger, and due to the increased density of these particles, the active material's effective area decreases, and the active material of the particle V3 becomes larger. The capacity of the zinc electrode decreases because it cannot be used for charging and discharging, and if giant zinc particles are present in the negative electrode active material, these giant particles become nuclei and zinc dendrites grow, causing short-circuit phenomena between the positive and negative electrodes. There are drawbacks.
この原因は負極活物質である亜鉛がアルカリ電解液に溶
解することに起因する。特に亜鉛のプント２イトの生長

ない程度に規制し、亜鉛の溶解を極刀抑えることが提案
されている。また特開昭５８−１ｓ８８６７号公報では
亜鉛粒子の巨大化防止のために粒径の小さい亜鉛ｔ負極
活物質として使用することが提案さｎている。This is due to the fact that zinc, which is a negative electrode active material, dissolves in the alkaline electrolyte. In particular, the internal short circuit between the positive and negative electrodes due to the growth of zinc punts is a problem that must be solved, and in order to improve this point even a little, the
Publication No. 29548 proposes that the dissolution of zinc be extremely suppressed by controlling the electrolyte solution tt to such an extent that no free material exists. Further, in Japanese Patent Application Laid-Open No. 58-1S8867, it is proposed to use zinc as a negative electrode active material having a small particle size in order to prevent zinc particles from becoming large.
しかしながら前記方法に工つても亜鉛活物質の緻密化を
阻止するのば十分ではない。これは光放電の繰り返しに

鉛活物質の反応性が低下するので、亜鉛極の利用率が著
しく低下しサイクル特注が劣化することになる。However, even with the above method, it is not sufficient to prevent the densification of the zinc active material. This is because the zinc active material on the surface of the zinc electrode becomes dense due to repeated photodischarges, which reduces the porosity of the surface of the electrode, and the electrode surface is closed, making it difficult for the electrolyte to diffuse to the same part of the electrode. As a result, the zincate ion concentration in the interior of the zinc electrode is lower than in the surface area, and the reactivity of the zinc active material in the electrode V3 portion is reduced, resulting in a significant decrease in the utilization rate of the zinc electrode and deterioration of the cycle customization.

Ｆ３部への拡散が優れることから、亜鉛極同部迄反応が
円滑に進むのでティクル特性が同上したものである。It can be seen from FIG. 2 that the cycle characteristics of the battery A of the present invention are excellent. This is because the surface of the zinc electrode in Comparative IC Cell B becomes dense as the number of cycles progresses, making it difficult for the tJL solution to penetrate, reducing the photodischarge efficiency and, as a result, deteriorating the battery characteristics. On the other hand, since the zinc electrode in the electrolyte of the present invention is highly porous, the densification of the surface is suppressed, and the zinc electrode F of the electrolyte is suppressed.
Since the diffusion into the F3 part is excellent, the reaction proceeds smoothly up to the same part of the zinc electrode, so that the tickle properties are the same as above.
