【発明の詳細な説明】 産業上の利用分野 本発明は、アルカリ電池用ニッケル極に関するものであ

Description of the Related Art Conventional Problems and Problems There are nickel electrodes used in alkaline batteries, in which a substrate obtained by normally sintering nickel powder on a perforated steel plate or the like is impregnated with a nickel salt and neutralized with an alkaline solution to obtain an active material.
しかしこのものは、実用上基板の多孔度は８０％が限界
であり、穿孔鋼板等の芯金を必要とすることから、活物
質の充填密度が小さくなる。さらに細孔が１０μｍ以下
と小さいために、活物質の充填方法は溶液含浸法に限定
されるので、煩雑な工程を数サイクルも繰返すためにコ
ストが高くなる等の欠点がある。However, in this product, the porosity of the substrate is practically limited to 80%, and a core metal such as a perforated steel plate is required, so that the packing density of the active material becomes small. Furthermore, since the pores are as small as 10 μm or less, the method of filling the active material is limited to the solution impregnation method, and there are drawbacks such that the complicated steps are repeated for several cycles, resulting in high cost.

物質粉末をスラリー状として充填するペースト式極板が
ある。しかしこの極板は焼結式極板に比べ著しく活物質
利用率が悪く、実用上使用し得なかった。As an attempt to improve these drawbacks, for example, there is a paste-type electrode plate in which a nickel hydroxide active material powder is filled in a slurry form in an alkali-resistant metal fiber sintered body having no core metal. However, this electrode plate was remarkably inferior in utilization rate of the active material to the sintered electrode plate and could not be practically used.

よって大きく左右される。Cobalt hydroxide powder is added as an effective means for improving the utilization rate of the active material. However, not all of the added cobalt hydroxide is effective, and it depends largely on its crystal structure.

工程を煩雑にし、かつ極板寿命や、酸素吸収に対して悪
影響をもたらす欠点がある。There are divalent and trivalent cobalt hydroxides. However, even if trivalent cobalt is added, the utilization rate of the active material cannot be improved. To improve the utilization rate, it dissolves in an alkaline electrolyte and divalent blue complexion is added.
(HCoO 2 − ) must be generated, and at the noble potential, they must be converted into a conductive CoOOH compound, and the active material surface must be coated. For this purpose, measures are taken such as leaving it in the alkaline electrolyte for a long time, or leaving it in a high-concentration alkaline electrolyte at high temperature in order to improve the solubility. However, these have the drawbacks of complicating the battery manufacturing process and adversely affecting the life of the electrode plate and oxygen absorption.

A nickel fiber sintered substrate is obtained by sintering for 5 to 20 minutes. The average pore diameter of the substrate can be adjusted to 10, 40, 70, 100, 150 μm by the fiber diameter or the fiber amount.

H) 2 is prepared to have an average particle size of about 5 μm.

スを増粘剤とする水溶液を加えてスラリー状とする。90 wt% of the above nickel hydroxide powder and α-Co (O
H) 2 10 wt% is mixed and an aqueous solution containing carboxymethyl cellulose as a thickener is added to form a slurry.
このスラリーを多孔度９５％、厚さ１．３mm、平均細孔

填し、乾燥、厚み調節により、厚み０．７mmのニッケル
極とした。これらのニッケル極の活物質利用率を調べた
結果を第１表に示した。This slurry was filled into a substrate having a porosity of 95%, a thickness of 1.3 mm, and an average pore diameter of 10, 40, 70, 100, 150 μm, and dried to adjust the thickness to obtain a nickel electrode having a thickness of 0.7 mm. Table 1 shows the results of examining the utilization rates of the active materials of these nickel electrodes.
なお、活物質利用率とは、ニッケル極の実電気容量を理

の理論電気容量は、水酸化ニッケル１ｇ当たりの理論電
気容量である２８９ｍＡｈに、充填した水酸化ニッケル
の重量を掛けて求める。The active material utilization rate means a value obtained by dividing the actual electric capacity of the nickel electrode by the theoretical electric capacity and multiplying by 100. Here, the actual electric capacity of the nickel electrode was obtained by discharging a potassium hydroxide aqueous solution with the cadmium electrode as a counter electrode,
The discharge electric capacity is measured and determined. Further, the theoretical electric capacity of the nickel electrode is obtained by multiplying the theoretical electric capacity of 289 mAh per 1 g of nickel hydroxide by the weight of the filled nickel hydroxide.
上記結果より細孔径は、４０〜１００μｍが適切であ
る。 From the above results, it is appropriate that the pore size is 40 to 100 μm.
尚、１０μｍの細孔径のものは、活物質粒子が繊維内部
に入らずオーバーペーストとなり脱落を生じた。In the case of the pore size of 10 μm, the active material particles did not enter the inside of the fiber and became an overpaste, which was removed.
次に、細孔径が４０μｍの基板に水酸化ニッケル粒子径
が細孔径の１／４，１／３，１／２，１である活物質
に、α−Ｃｏ（ＯＨ）２の粒子径が水酸化ニッケル粒子

製したニッケル極の活物質利用率を第２表に示した。Next, an active material having a nickel hydroxide particle diameter of 1/4, 1/3, 1/2, 1 of the pore diameter on a substrate having a pore diameter of 40 μm and an α-Co (OH) 2 particle diameter of water. Table 2 shows the utilization rate of the active material of the nickel electrode produced by adding the nickel oxide particles having a ratio of 1/3, 1/2, 1 of the particle diameter.
上記結果より水酸化ニッケル粒径が細孔径の１／３以下
であり、水酸化コバルトの粒径が水酸化ニッケルの粒径
の１／２以下であるものが最も優れている。 From the above results, it is most excellent that the particle size of nickel hydroxide is 1/3 or less of the pore size and the particle size of cobalt hydroxide is 1/2 or less of the particle size of nickel hydroxide.
α−Ｃｏ（ＯＨ）２に替えてＣｏＯあるいはβ−Ｃｏ
（ＯＨ）２の粒径との関係についても調べたところ、第
２表と同様の結果を得た。CoO or β-Co instead of α-Co (OH) 2
When the relationship with the particle size of (OH) 2 was also investigated, the same results as in Table 2 were obtained.
尚、耐アルカリ性繊維多孔体の実施例としてニッケル繊
維焼結体について述べたが、ニッケルメッキ鉄繊維焼結
体、ニッケルメッキグラファイト繊維体であっても同様
である。Although the nickel fiber sintered body has been described as an example of the alkali resistant porous fiber body, the same applies to the nickel plated iron fiber sintered body and the nickel plated graphite fiber body.
水酸化ニッケル粒子径が、基板細孔内の１／３以上での
利用率の低下は基板内部への充填が不均一化するためで
あると考えられる。又、繊維細孔径が１００μｍ以上に
なるとＣｏＯＯＨの電導性コーティング被覆でも高率放
電においては、金属繊維と活物質間距離が長くなりす
ぎ、充分な利用率を得ることは困難である。It is considered that the decrease in the utilization rate when the diameter of nickel hydroxide particles is 1/3 or more in the pores of the substrate is because the filling inside the substrate becomes non-uniform. Further, if the fiber pore diameter is 100 μm or more, the distance between the metal fiber and the active material becomes too long at high rate discharge even with the CoOOH conductive coating coating, and it is difficult to obtain a sufficient utilization rate.
又、繊維細孔径が１０μｍ以下では活物質の充填が困難
となる。If the fiber pore size is 10 μm or less, it becomes difficult to fill the active material.
添加コバルト化合物粉末の粒子径が水酸化ニッケル粉末
粒子径よりも大きいと少量添加したコバルト化合物粉末
の活物質粒子間への分散度が悪く、均一コーティングし
得ないために活物質利用率が悪くなる。If the particle size of the added cobalt compound powder is larger than the particle size of nickel hydroxide powder, the degree of dispersion of the cobalt compound powder added in a small amount between the active material particles is poor and the active material utilization rate becomes poor because uniform coating cannot be performed. .
発明の効果 上述した如く、本発明は活物質利用率の向上した、高性
能で高容量かつ生産性の高いアルカリ電池用ニッケル極
を提供することが出来るので、その工業的価値は極めて
大である。EFFECTS OF THE INVENTION As described above, the present invention can provide a nickel electrode for an alkaline battery, which has a high utilization rate of an active material, a high performance, a high capacity, and a high productivity, and therefore its industrial value is extremely large. .
