本発明は円筒用密閉型ニツケル−カドミウム蓄
電池の正極板に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a positive electrode plate for a cylindrical sealed nickel-cadmium storage battery.
従来例の構成とその問題点
従来、この種の電池の正極の製造法としては、
大別していわゆる焼結式とペースト式とがある。

スポンジ状多孔体の空孔部に物理的に充填した
後、乾燥して正極板とする方法がある。Conventional structure and its problems Conventionally, the method for manufacturing the positive electrode of this type of battery is as follows:
There are two main types: sinter type and paste type.
The so-called sintering method is a porous substrate obtained by kneading carbonyl nickel powder with a binder to form a paste, applying it onto a conductive core material, and sintering it in a reducing atmosphere. Chemically inject Ni(OH) 2 into the pores of
Alternatively, it can be electrochemically generated and activated to be used as an electrode plate. The other type, called the paste method, is made by adding short fibers, a binder, and water to an active material mainly composed of nickel hydroxide, kneading it into a paste form, and applying it directly to a conductive core material. One method is to dry the active material to make an electrode plate, and the other is to make a sponge-like porous material made of nickel metal by kneading the active material, which is mainly nickel hydroxide, with an aqueous solution containing a binder or with just water to form a paste. There is a method of physically filling the pores of the material and then drying it to form a positive electrode plate.
ペースト式正極板の場合の大きな特徴として、
焼結式のように多孔質基板の空孔が微細なために
活物質を充填する方法として化学的、あるいは電
気化学的にしか充填できない方法と違つて、ペー

スポンジ状金属の大きな空孔部に直接充填できる
という特徴を持つている点があげられる。したが
つて、ペースト式の方が単位体積当りの活物質量
も多く、製造工程が簡易であるという長所を持
つ。 The main features of the paste type positive electrode plate are:
Unlike the sintering method, which can only fill the active material chemically or electrochemically because the pores in the porous substrate are so small, it is possible to fill the active material physically into the core by physically filling the paste-like active material. Its unique feature is that it can be applied to materials or directly filled into large pores in sponge-like metal. Therefore, the paste type has the advantage that the amount of active material per unit volume is larger and the manufacturing process is simpler.
しかし、粒径（＝70μｍ）の大きい活物質を
直接充填するため、極板表面からの脱離が多く、
また焼結式に比べると芯材部の金属量が少なく、
極板の曲げに対する強度は著しく低下する。とり
わけスポンジ状金属多孔体を用いるペースト式製
造法について、これらの傾向が顕著である。 However, since the active material with a large particle size (=70μm) is directly filled, it often detaches from the electrode plate surface.
Also, compared to the sintered type, the amount of metal in the core material is smaller,
The bending strength of the electrode plate is significantly reduced. These trends are particularly noticeable in paste-type manufacturing methods that use sponge-like porous metal bodies.

た、極板の曲げ強度が弱いため、極板群捲回構成
時に正極板の一部に亀裂が生じ、リーク不良の原
因となつたり、電池特性面からみても大電流放電
時の放電効率に悪い影響を及ぼす危険性がある。 Currently, for surface desorption of active materials, a method is used in which the active material is immersed in an active material holding agent such as a polyflon dispersion. However, a side effect of immersion in the Polyflon dispersion is that the liquid absorption rate of the electrode plate group becomes slow when the electrolyte is injected. In addition, because the bending strength of the electrode plate is weak, cracks may occur in a part of the positive electrode plate when the electrode plate is wound in groups, causing leakage defects and, from the viewpoint of battery characteristics, discharging efficiency during large current discharge. There is a risk of adverse effects.

The purpose is to improve leakage defects caused by cracks in the positive electrode plate, improve battery characteristics, and speed up liquid injection speed.

に、Ｖ字状の溝を設けたことを特徴とする。Structure of the Invention In order to achieve the above object, in the present invention, a paste-like active material mainly composed of nickel hydroxide mixed with water or an aqueous binder solution is filled into the pores of a sponge-like porous body of nickel metal. A V-shaped groove is provided on the surface of the positive electrode plate in a direction perpendicular to the winding direction of the electrode plate when forming the group.

液の速度を上げるものである。 When the positive electrode plate is wound, the inner circumferential side, which is the center of the winding axis, is compressed, while the outer circumferential side of the winding is expanded. At this time, cracks occur, particularly on the outer circumferential side, which eventually ruptures the separator and short-circuits with the negative electrode plate, resulting in a failure. In the present invention, the V-shaped groove formed in the positive electrode plate alleviates the expansion and contraction of the inner and outer circumferential sides and eliminates cracks, thereby reducing leak defects due to cracks and improving the large current discharge rate. . At the same time,
When injecting the electrolyte, the above-mentioned grooves facilitate the replacement of the electrolyte with the air inside the battery, thereby increasing the speed of injecting the electrolyte.

After adding and kneading for about 20 minutes, it is filled into the pores of a 1.1 mm thick nickel metal sponge-like porous body. After drying at 80°C, two V-shaped grooves 2 with a depth of 0.15 mm are made on both the front and back sides of the electrode plate 1, as shown in Figure 1.
They are arranged at equal intervals of mm and pressed so that the thickness of the electrode plate other than the V-shaped groove is 0.7 mm. Thereafter, if necessary, the vertical end faces of the electrode plate 1 are exposed or the leads 3 are attached as shown in FIG. Second
The arrow in the figure indicates the direction of winding.

面に亀裂は見られなかつた。Example 1 The electrode plate obtained by the above method, a cadmium negative electrode plate partially made of metal cadmium, and a separator made of nylon nonwoven fabric were combined and wound around a shaft core with a diameter of 3.5 mm. No cracks were observed on the surface of the electrode plate on the outer periphery of the winding, as was seen in the positive electrode plate obtained in .

た。Example 2 Next, the electrode plate group obtained in Example 1 was placed in an AA-sized container, and the injection rate of 20 cc of a caustic potassium aqueous solution with a specific gravity of 1.2 was measured. Measurements were carried out on 100 cells each using the conventional method and the method according to the present invention. In the case of the conventional method, it takes 40 seconds to 1 minute to absorb all the electrolyte into the group.
It was found that liquid injection was completed in 20 to 30 seconds when using the positive electrode according to the present invention, compared to the time it took for 20 to 30 seconds.
このことは群の高さ方向に存在するＶ字状の溝

くしている理由によると思われる。 This is why the V-shaped grooves that exist in the height direction of the group act as ventilation holes, making it easier for the air that is replaced by the liquid when the electrolyte is injected to escape out of the group. It seems to be based on.

くくなるためである。Example 3 Thirty batteries each obtained in Example 2 were charged at 20°C and 0.1CA for 16 hours, and then discharged.
Performed with 0.2CA, 1CA, 2CA, 3CA, 5CA
1CA/0.2CA, 2CA/0.2CA, 3CA/0.2CA,
The average discharge rate of 5CA/0.2CA was compared with the conventional method. Figure 3 shows the results. In the figure, A shows the case according to the present invention, and B shows the case where a conventional positive electrode plate is used. As shown in FIG. 3, in the case of the conventional method, the discharge rate decreases as the current discharge becomes larger than that of the present invention. This is because the sponge-like metal mesh, which is a conductive path within the positive electrode, is cut by cracks that occur when forming the electrode plate group, making it difficult for large current to flow.
極板表面に形成する溝の深さは極板厚さに対し

縮を吸収しきれないため、捲回時に亀裂が生じて
しまう。また30％以上では極板厚さに対する溝の
深さの割合が大きくなり過ぎて、スポンジ状多孔
体の曲げに対する強度が弱くなるので切れなどの
問題を生じる。 The appropriate depth for the grooves formed on the surface of the electrode plate is 5 to 30% of the thickness of the electrode plate; if it is less than 5%, it will not be able to absorb the expansion and contraction of the electrode plate, resulting in cracks during winding. . Moreover, if it exceeds 30%, the ratio of the depth of the groove to the thickness of the electrode plate becomes too large, and the strength against bending of the sponge-like porous body becomes weak, causing problems such as breakage.
また、溝と溝との間隔は１mm〜５mmが適当であ
り、１mm以下の場合、全体的に容量密度（ｍ
Ah／cc）が高くなり、かえつて極板を固く折れ
易くするし、５mmよりも間隙が広い場合は軸芯の
近辺の捲き径の小さい部分で伸縮を吸収しきれな
い。 In addition, the appropriate distance between the grooves is 1 mm to 5 mm, and if the interval is 1 mm or less, the overall capacity density (m
Ah/cc) becomes high, which makes the electrode plate hard and easy to break.If the gap is wider than 5mm, the part with a small winding diameter near the shaft core cannot absorb the expansion and contraction.

In the present invention, in which the character-shaped groove is present, it is possible to eliminate cracks that occur when winding the positive electrode plate, prevent leakage defects and deterioration of discharge rate characteristics caused by cracks, and prevent electrolysis. The liquid injection speed can be increased.
