６−１４５６６８号公報などで提案されている。DETAILED DESCRIPTION OF THE INVENTION A) Industrial Application Field The present invention relates to improvement of a battery electrode using a felt-like conductive porous body made of sintered metal fibers as an active material support. Electrodes, especially nickel anodes for alkaline storage batteries,
The sintering method was mainly used, but in recent years, sponge-like porous metal materials made of a three-dimensional conductive matrix with continuous pores and other materials have been developed because the manufacturing process is simple and it is easy to increase energy density. The use of an electrode in which a felt-like conductive porous body or the like is used as a conductive material and an active material holder, and a separately produced active material powder is filled and held in the pores is used as disclosed in JP-A-59-83346 and JP-A-59-83346. Kaisho 5
This method has been proposed in, for example, Japanese Patent No. 6-145668.

が増加したりするため、極板のエネルギー密度が低下す
るという問題がある。The sponge-like porous metal material described above has an average pore diameter of 20
0 to 300μ, whereas the felt-like conductive porous material has a smaller average pore diameter of 5o to 6oμ, and therefore the felt-like conductive porous material has a greater active material retention power than the sponge-like metal porous material. Also, it has the advantage of good contact with the active material and excellent electrode properties. However, even with this felt-like conductive porous material, the retention of active material particles is still not sufficient. For this reason, it is possible to increase the fiber density to prevent the active material from falling off.
In this case, the filling property of the active material deteriorates and the number of overlapping electrode plates increases, resulting in a problem that the energy density of the electrode plates decreases.

も低かった。On the other hand, the active materials filled in these active material holders are:
Conventionally, amorphous particles of nickel hydroxide with an average particle size of 2 to 1 μm have been used, but since these particles have an irregular shape and many irregularities on the surface, entanglement between particles is strong, and they do not adhere to the active material support. The filling properties were poor, and the uniformity of the filled active material was also low.

Publication No. 110966 proposes the use of an electrode plate in which the pores of a felt-like conductor made of conductive fibers with fine irregularities on the surface are filled with a mixture mainly composed of spherical active materials. However, it was difficult to provide unevenness on the surface of the metal fiber, and the active material retention ability was not fully satisfactory.

位体積あたりの充痔量も大きくすることができる。(e) Function When a spherical active material such as spherical nickel hydroxide is used as the active material filled in the conductive porous body, the active material powder has almost no entanglement between particles and has high fluidity, so the average number of pores Even a felt-like conductive porous material having a relatively small pore diameter can be easily and uniformly filled with one pore. Furthermore, since the active material powder has a spherical outer shape, it has a high apparent density and can increase the amount of hemorrhoids filled per unit volume.

され脱落することが防止できる。On the other hand, the conductive porous body that holds the active material is created by sintering nickel fibers and nickel powder or nickel oxide powder in a reducing atmosphere, bonding the nickel powder to the nickel fibers, and forming irregularities at the nickel fiber interface. It is easy to form unevenness, and by adjusting the amount of nickel powder bonded to the nickel fiber, the size of the unevenness on the surface of the nickel fiber can be adjusted to an appropriate size. Even when filled with a spherical active material that easily falls off from the holder, the active material particles are captured by the irregularities on the surface of the nickel fibers and can be prevented from falling off.

It is desirable that the amount of nickel powder be 10 to 25% by weight, and if the amount of nickel powder is less than this, the ability to retain the active material will decrease and the number of active material falling off will increase. When the amount increases, it becomes difficult to fill the active material and the filling rate decreases.

性を持つことには違いない。From the above table, it can be seen that the electrode plate of the present invention is excellent in all of the active material filling property, active material holding power, and homogeneity. In addition, there are some differences in active material filling ability and active material retention between Example 1, which used nickel powder as the powder to be sintered with nickel fibers, and Example 2, which used nickel oxide powder. This is due to the difference in the characteristics of each powder; nickel powder has a chain-like, uneven shape, while nickel oxide powder has a granular shape close to a sphere, so it has a felt-like shape. Inside the conductive porous body, the former has a large ability to capture active material particles and has a large drop-off prevention effect, but the filling property is somewhat reduced, and the latter does not reduce the filling property so much, but the drop-off preventive effect is not as great as the former. However, in any case, there is no doubt that it has a great advantage over the comparative example.

している。Next, various felt-like conductive porous bodies in Example 1 were prepared by varying the ratio of nickel fiber to nickel powder, and the active material was filled into the porous bodies in the same manner as in Example 1. Obtained the electrode plate. FIG. 5 is a diagram showing the relationship between the amount of active material filled in the electrode plate and the amount of active material falling off, and the ratio of nickel powder in the porous body, where the filling amount is shown by ◯ and the falling amount is shown by .

の活物質保持量が減少するためと考えられる。As is clear from Figure 5, the ratio of nickel fibers and nickel powder that make up the felt-like conductive porous body has a large relationship with the active material filling lid and the amount of falling off.
Excellent active material filling properties and active material holding power are obtained when the nickel fiber content is 0 to 25% by weight and 90 to 75% by weight. In addition, when the felt-like conductive porous body is composed only of nickel fibers, the active material filling amount is small when the nickel powder ratio is 0%) because the active material retention force of the felt-like conductive porous body is small. It is thought that this is because the amount of active material falling off during filling is increased, and the amount of active material retained at the end of the filling operation is reduced.
