る。Structures of conventional examples and their problems When aiming to improve electrode characteristics, especially active material utilization rate and high rate discharge characteristics, in battery electrodes currently used industrially, and when repeatedly charging and discharging. When used in secondary battery electrodes that require physical properties, sintered substrates, grids, and microporous metals that generally have a three-dimensional floor and have high electronic conductivity are used. A bag is used as a support. Among these, the electrode that is generally the best in terms of the electrode properties and robustness mentioned above is a sintered wire electrode using a sintered substrate as a support. On the other hand, since the pores of this electrode are small, filling the electrode with the active material requires a relatively complicated process and is somewhat expensive.

スト状の混線物を振動、摺動。In addition to these supports, very high porosity (
96% or more) and a large pore diameter, and an electrode for use in a foamed metal porous body or a metallic nonwoven fabric entire support body, in which the pore diameter can be arbitrarily selected, has been proposed. Among them, the foamed metal porous body has a three-dimensional network cell a, so the electronic conductivity of the entire electrode is excellent, and has characteristics extremely similar to those of a sintered electrode. In addition, by appropriately selecting the hole diameter, it is possible to directly fill the active material powder, and the electrode has the feature that it can be manufactured through a much simpler process than a sintered electrode. The active material filling method for electrodes using this foamed metal porous material involves vibrating and sliding a paste-like mixed material mainly composed of active material powder.
吸引および吹き向は等の手段で充填する方法がある。There are several methods of filling, such as suction and blow direction.
このうちでもペースト状混練物を吹きつけて基体内部に

状混練物（以下ペーストという）をノズルで吹き伺は充
填する方法を提案した。In other words, basically the main equipment is a pump that provides flow velocity, its piping, and a nozzle for spraying. However, after examining various filling methods for this spraying method, we found that it is possible to use only one nozzle, and in other words, it is possible to obtain more uniform filling by filling almost vertically from both sides of the substrate than by filling from one side of the substrate. It turned out that. Therefore, the present inventors proposed a method of blowing and filling a paste-like kneaded material (hereinafter referred to as paste) into a substrate as shown in FIGS. 1 and 2 from both the left and right sides of the substrate using a nozzle.

た。To roughly explain this, Fig. 1 shows a porous metal substrate 1 that is moved horizontally with its width as the top and bottom, and paste 2 is blown onto it from symmetrical nozzles 3 and 4 with elongated air outlets. is to be filled, and FIG. 2 shows the base 1
While moving the liquid upward, it is filled with a pace l-i spray from nozzles 3 and 4 arranged symmetrically in the horizontal direction. Note that 5 is a paste transfer pipe. However, with this method, a problem of congestion occurred when the scale of the apparatus was increased. In other words, when the amount of paste blown out from the nozzle increases, this is a phenomenon that would have been unimaginable on a small scale, but when the paste is blown out from the center of the blown paste, for example from a circular outlet, the amount of paste that is blown out from the nozzle increases, which corresponds to the center of the circle. A phenomenon was observed in which the amount of filling into the substrate decreased.
そとで小径なノズルを束にしたり、回数を別けて順次ず
らして充填する方法も考えられたが、設備の簡素化の点
では吹き出しペーストに一度挿入（通過）するだけで充
填することが好ましい。Methods such as bundling small-diameter nozzles outside or filling the nozzles by staggering them several times have been considered, but in terms of simplifying the equipment, it is preferable to fill the paste by inserting it (passing through) it once. .

填ができにくくなると考え、流速の低下した充填に関係
ないペーストが基体表面を被覆して新たなペーストの基
体内への充填を阻止するのではないかと推定した。Therefore, the amount of filling in the center of the paste blowout is reduced because some of the paste that blows out fills the base and the rest is difficult to flow out. We assumed that the filling of the center of the nozzle would become difficult, and that the paste unrelated to filling, whose flow rate had decreased, would coat the surface of the substrate and prevent new paste from filling into the substrate.

The nozzle outlet was set at an angle rather than perpendicular to the normal line of the substrate so that the paste supplied later would be easily dissipated, and when the spray was applied to the substrate at an angle, the area corresponding to the center of the nozzle It has been found that the phenomenon of a decrease in the amount of filling can be prevented.

That is.

ｏ０の吹き付は入射角をもってペーストを基体に吹き付
けることを特徴とする。Structure of the Invention The present invention provides an outlet of a nozzle for spraying paste onto a substrate in the form of a thin strip, that is, a rectangular or oval shape, which is approximately symmetrical to the substrate, and has a diameter of 6 to 3 mm with respect to the normal to the substrate.
The o0 spraying is characterized by spraying the paste onto the substrate at an incident angle.

ある。The main point of the present invention in spraying and filling is that instead of spraying from the nozzles placed on both the left and right sides of the substrate at a perpendicular angle of incidence O equal to the normal line of the substrate as in the conventional example, the spraying is performed at an angle of 5 to 300 from the normal line. The process involves arranging the nozzle and spraying.
以下、本発明の詳細は実施例により説明する。The details of the present invention will be explained below using examples.

It is substantially symmetrical with respect to the substrate, faces toward the direction of movement of the substrate, and has an incident angle inclined by θ from the normal to the substrate.

は均一に生じることか均−充ｊ■の上から必要である。The principle of paste filling using a nozzle arranged in this way is that the paste given the necessary flow velocity passes through the space of the substrate (mostly flows on the surface without being filled), and the original paste is transferred to the substrate. It fills the space and fills the space while reproducing its composition. However, it is necessary for the paste to pass through the base uniformly or evenly.

く（長手方向はペーストを充填する基体の幅だけは必要

に通過できるだけの吹き出し口幅は必要である。In other words, if the solid parts are collected in the grid or if the flow rate necessary for filling is not given to the paste and some parts cannot be filled, this will cause uneven filling. The latter lack of flow speed requires
This is thought to occur when the paste sprayed onto the surface of the substrate is not sufficiently scattered and remains. In fact, after various studies, it is preferable to make the outlet of the blowing nozzle narrow (in the longitudinal direction, only the width of the substrate filled with paste is necessary) in order to facilitate the dispersion of the paste from the surface of the substrate. . However, the outlet must be wide enough to allow particles to easily pass through the nozzle.
この充填方法は基体の孔径より小さい粒子の充填には、
何れも適用が可能である。そこで具体例では、活物質に
水酸化ニッケル粉末を用いた場合について述べる。This filling method is suitable for filling particles smaller than the pore size of the substrate.

る。The air was sucked up by the Conobase +-1 pump, and passed through a nozzle (inner cross section 2ffff x 150mm) with the incident angle θ of both nozzles 3 and 4 about 10° as shown in Fig. 3 at a flow rate of 6 m/sec. (Porosity: 96%, average pore size: 20

ケル電極を得た。(Example 2) In Example 1, the incident angles θ of the nozzles 3 and 4 with respect to the substrate 1 were both set to about 30°, and a nickel electrode was obtained by the same operation as in Example 1.

べた。In Example 1, the filling distribution of the pasty active material in the nickel electrode when the nozzle angle was changed was examined by cutting the nickel electrode finely into 5 rows in a square shape of 20 mm on each side and measuring the weight.
その結果、幅方向端部の第１列と第６列及び長さ方向の

Although it was observed that there was little variation in filling the space of the substrate (nearly 0% filled), it was found that the filling amount decreased in the other horizontal rows and inside the substrate in the 2nd to 4th rows (in the direction of the center). Admitted. As an example, FIG. 4a shows the filling amount of cut pieces in the same location, for example, the third row in the horizontal direction and the 20th row in the longitudinal direction, as an average value of 10 pieces.

である。As is clear from FIG. 4, when the incident angle is increased from Q to 5°, the amount of filling increases, and becomes almost steady from 5° to around 30°. However, when the angle was increased to 30° or more, the filling amount tended to decrease again. For comparison, the edges with a large amount of filling, for example, the corners of the 20th row of the 1st horizontal row, the 1st horizontal flute, and the 6th row in the longitudinal direction, are taken and similarly shown.
It is.
