板の細孔内に充填して製造される。Sintering type! For the electrode, for example, a slurry mainly composed of nickel powder is applied to the surface of a porous conductive core and then sintered to obtain a porous sintered substrate, and the pores are filled with the substrate as an active material holder. It is manufactured by filling the active material into the pores of the substrate through a chemical impregnation operation in which the substrate is impregnated with a metal salt solution such as a nickel salt solution or a cadmium salt solution, and then the metal salt is converted into a hydroxide using an alkali. .

参照）することが提案されている。The amount of active material filled in such a sintered substrate is determined by the porosity of the sintered substrate. Therefore, in order to improve the porosity, organic hollow spheres were added to the slurry (Japanese Patent Laid-Open No. 61-1
．． 85865) or adding polystyrene fine powder to the slurry (see Japanese Patent Laid-Open No. 175565/1983).

いう問題がある。(c) When organic hollow spheres are used as a shaping agent as described in the problem to be solved by the invention, the shaping agent causes a thermal expansion phenomenon during sintering, resulting in unevenness of bubbles. . As a result, variations in porosity are observed in the sintered substrate, making it difficult to adjust the filling amount of the active material to tI-no, resulting in a problem that an electrode of stable quality cannot be obtained.

えるという問題を′１：しる。On the other hand, organic polymers such as polystyrene can be used as a shaping agent.
When fat powder is used, the above-mentioned variation in porosity in the sintered substrate is not observed, but during sintering, the decomposition products of the organic polymer sugar remain as residue in the sintered substrate. . As a result, there is a problem that this residue adversely affects the electrode characteristics.
そしてこれら造化剤の使用は、焼結基板製造コストを上

ものである。Therefore, the present invention has been made in view of these points, and it is possible to obtain high porosity even when no forming agent is used, and also to improve the adhesion between nickel particles and between nickel particles and the conductive core. The purpose is to obtain a sintered substrate that has excellent properties and high mechanical strength.

After that, it is preferable to sinter in a reducing atmosphere,
The carbonyl nickel powder has an average particle size of 360 to 4.
It is characterized by using a material with a diameter of 0 μm.

完成するに至ったものである。(E) Effect 4 The inventor discovered that the porosity and mechanical strength of the sintered substrate, as well as the ease of handling when forming an electrode, depend on the particle size of the carbonyl nickel powder. , which led to the completion of the present invention.

とする際に、平均粒径が２２〜２ 、８７ｙ ｍのカー
ボニルニッケル粉末であれば、焼結体の幹が細く、強度
的にも穐い焼結基板しか得られない。That is, when trying to obtain a porosity of 85% or more in a sintered substrate, if carbonyl nickel powder has an average particle size of 22 to 2.87 mm, the body of the sintered body will be thin and the strength will be However, only a solid sintered substrate can be obtained.

縮が進行しやすく、多孔度の低下を招く傾向が大きい。The average particle size of carbonyl nickel powder is 22~2
, 81. If it is within the r m range, the trunk is thin, so shrinkage during sintering tends to progress, and there is a strong tendency for the porosity to decrease.

優れた焼結基板が得らｊ′Ｌる。However, if the average particle size exceeds 3.0 μn1, it tends to be difficult to shrink during sintering, making it possible to maintain a high porosity. In this case, since the particle size of the carbonyl nitride powder is large, the trunk of the sintered body is thick and forms a strong skeleton. As a result, a sintered substrate with high porosity and excellent strength can be obtained.

t) If (r n) is exceeded, when used as an electrode in a rotating configuration, the flexibility decreases and the active material falls off.As a result, the electrode has the characteristics of high porosity and excellent mechanical strength. It becomes difficult to perform.

Since the adhesion between the 2L Kel powder and the conductive core improves the conductivity, as a result, the sintered substrate has a high porosity as shown in Figure f-L. As a result, a stable electrode with high strength and quality can be obtained.
