This relates to a method of manufacturing electrodes for batteries, and its purpose is to fill a foamed metal with a lead terminal attachment part with an active material, and then fill the active material in the form of a paste that adheres to the surface of the lead terminal attachment part. mechanically removing the material until the core material is exposed;
Next, the lead terminal is spot welded by impregnating it with a binder liquid, such as an aqueous dispersion of fluorine resin, to prevent the filled active material from falling off, and then removing the binder liquid from the surface of the lead terminal attachment part. When attaching with a machine, the purpose is to reduce the resistance of that part to make it easier to attach the lead terminal.

加したところ、次のような問題点を発生した。 However, in this method, the active material filling process is complicated and requires repeated filling, so there has been a demand for rationalization of the manufacturing process. Therefore, in contrast to this method, the method of directly filling a nickel foam metal with a relatively small pore size with a paste-like active material and applying pressure to form an electrode is a method that prevents the active material from falling off. A high capacity can be expected because there is little decrease in capacity and a large amount of active material can be filled. However, in this case, when the active material was filled into the foamed metal provided with the lead terminal mounting portion by applying pressure in a concave shape, and then the binder was added, the following problems occurred.

る。 That is, in the step of providing a recessed lead terminal attachment part of a certain size by applying pressure at the end of a long strip-shaped foamed metal, and continuously filling the active material and containing the binder, the above-mentioned Paste-like active material was directly filled into foamed metal, but in this case,
At the same time as filling the inside of the foamed metal, the active material also enters the recessed lead terminal attachment part. If an active material such as nickel hydroxide is thickly adhered to the surface of the lead terminal attachment portion, a large electrical resistance will be generated when attaching the lead terminal, making it difficult to attach the lead terminal. Furthermore, since the binder liquid is impregnated thereon, the resistance further increases. Therefore, if the active material on the surface of the lead terminal attachment part is removed and then impregnated with a binder liquid, the improvement can be improved slightly, but since the binder liquid accumulates on the surface of the lead terminal attachment part, the binding will not occur after drying. A film of adhesive is formed, and the film has a large electrical resistance, making it difficult to attach the lead terminal.

It is designed to remove the chemical solution.

First, a lead terminal mounting portion 3 as shown in FIG. 2 is provided on a long strip-shaped foamed metal 1 using a pressurizing machine 2. As shown in FIG. Next, the foamed metal 1 enters a tank 4 containing a paste-like active material, and is mechanically filled with the active material. After the active material is filled, it is then dried by a dryer 5, and the excess active material that has entered the lead terminal attachment portion 3 is removed by a remover 6. Next, foam metal 1
is immersed in the binder liquid 7, and the excess binder liquid that has entered the lead terminal attachment part 3 is removed by a remover 8.
It is removed by a high-pressure gas blowing device or the like, dried by a dryer 9, and then cut under pressure into an appropriate size to form an electrode body.

した。 FIG. 3 shows an example of the active material removal tool 6 after being filled with the active material, or an example of the binder liquid removal tool 8 after being impregnated with the binder liquid. Effective materials for the active material removal tool 6 include a fine-grained soft mop, a puff, a non-metallic brush, and a metallic brush, but a metallic brush was used this time.

示すように、後者の方法を採用した。 In addition, effective methods for removing the binder liquid include scattering the liquid by blowing with high-pressure gas, scattering the liquid by suction, or absorbing the liquid with a hygroscopic material. This time, we adopted a method that blows high-pressure air onto the local area to scatter the liquid. In FIG. 3, since a metal brush 6a is disposed around the rotating removal tool 6, as the removal tool 6 rotates, the tip of the brush 6a is brought into contact with the surface of the lead terminal mounting portion 3. to remove excess active material. In this case, the contact portion between the two can be removed relatively completely by rotating in the opposite direction to the moving direction of the foam metal 1. Note that if the material is removed in the same direction, the removal efficiency is not good because the material that has been removed will accumulate and adhere to that part again. Further, in FIG. 3, high-pressure air is blown out at high speed from the nozzle 12 of the faucet 11 as indicated by arrow A, and the liquid on the lead terminal attachment portion 3 of the foamed metal 1 is blown off and removed. Especially foam metal 1
There are two ways to blow air: one is to blow air from above, and the other is to blow air from the side.This time, we adopted the latter method, as shown in Figure 3.

An appropriate amount of 0.5% by weight aqueous solution was added and stirred well to obtain a paste-like active material. As the binder liquid to be impregnated later, an aqueous dispersion of fluororesin (solid content: 0.5% by weight) was used. Also, long strip-shaped foam metal 1
used had a porosity of 97%, a length of 5 m, and a width of 100 mm, the moving speed was 0.5 mm/sec, and the pressure on the lead terminal attachment part 3 was manually applied. The size of the pressurizing part was 10 mm in width and 50 mm in length.

FIG. 4 shows the state of the lead terminal mounting portion 3' when it is filled with a paste-like active material using such an electrode manufacturing apparatus. That is, in the case shown in FIG. 4, when the paste-like active material is mechanically rubbed into the foamed metal 1' using a filling jig or the like, the active material 1 is applied to the lead terminal attachment part 3'.
3' is shown, and the effective active material is the active material 13 filled inside the foamed metal 1', and the active material 13' is unnecessary. Also, Figure 4 shows extra active material 1.
This shows the state after removing 3'.

As shown in FIG. 5, the liquid accumulates in the lead terminal mounting portion 3'. This case shows the state in which the active material 13' of the lead terminal attachment part 3' shown in FIG. 4 is removed and then the binder liquid 14 is impregnated. When dried in this state, a coating film 15 of the binder is formed on the surface of the lead terminal attachment portion 3', as shown in FIG. In addition, since the binder liquid contains a material with poor electrical conductivity, when the solvent is removed by drying, only a layer with poor electrical conductivity remains, resulting in a coating film with high electrical resistance. will be formed.

While preventing the formation of a binder film, the long strip-shaped substrate thus produced was cut to a regular size to form the electrode body 16 shown in FIG. 6. Further, a lead terminal 17 was attached to the lead terminal attaching portion 3 by welding with a spot welder. By doing this,
There were no problems with the attachment of the lead terminals 17, and the lead terminals 17 could be attached easily. In addition, when spot welding was performed in the same way on a conventional board in which active material remained in the lead terminal attachment part 3' or a binder coating was formed, most of the parts were found to have no lead terminals. Installation was impossible. Furthermore, increase the voltage of the spot welding machine,
If spot welded, sparks will be generated and the lead terminal attachment part will be destroyed.

い。 In the above example, the active material on the surface of the lead terminal attachment part was removed by rotating a remover made of a flexible metal brush, but it can also be removed mechanically, such as by reciprocating motion or circular motion. Any method is fine. In short, any method may be used as long as the tip of the flexible removal tool is brought into contact with the material to be removed while removing it from the lead terminal mounting portion.
