に換わる高多孔度金属多孔体の開発が鼠まれている。Prior art and points of interest In battery electrodes that require low cost and high energy density, efforts have been made to develop high-porosity metal porous bodies to replace the conventional low-porosity metal powder sintered active material support. There is.

な充填しかできないという欠点があった。Since these continuous band-shaped porous bodies are not microporous like conventional sintered bodies of metal powder, they can be directly filled with the active material. Conventional methods for filling this continuous band-shaped porous body with active material for batteries include the so-called calendar roll method in which paste-like active material is forced into the material using a four-fiber, and the method in which the active material is sprayed using a spray gun.
The former takes time to fill uniformly, and the latter also requires some time.
The drawback was that it could only be filled with

This is a filling method in which the porous body is filled in close proximity to the porous body with a gap provided therebetween without contacting the porous body.

テンションロールである。1 is a continuous band-shaped porous body, 2 is a paste tank, 3 is a reversing roll, and 4 is a roller having a plurality of grooves, which rotates in a direction opposite to the traveling direction of the band-shaped porous body. 5 is a fixed plate, and 6 is a tension roll.

性体の進行方向とは逆方向に回転する。The continuous strip-shaped porous body 1 is immersed in a paste tank 2 in which a paste-like active material is stored, and is pulled up through an inversion whirl 3. At this time, the porous body is pulled up along the fixing plate 5, and the paste-like active material is filled into the fields having a plurality of grooves on the fixing plate. This roller rotates in a direction opposite to the direction in which the porous body moves.

転させて近接させる。Normally, simply immersing a porous body in a paste-like active material does not push out the air bubbles inside the porous body, so that only the vicinity of the surface of the porous body is filled. In the present invention, a roller having a plurality of grooves is rotated in reverse in a paste solution and brought close to each other.

の流れが均一にな−るものと考える。The pasty active material near the surface of the porous body is intermittently compressed by rotating a roller with a plurality of grooves in the pasty active material in reverse to generate a constant flow velocity. As a result, the paste-like active material is gradually pushed inside. Air bubbles forced out by internal penetration of the paste-like active material are removed by a rotating roller. Uniform filling becomes possible by smoothly penetrating the paste and removing air bubbles accordingly. If the rotation speed of the drum is too slow or too fast,
It was found that there was no effect and that there were appropriate conditions. This condition may vary depending on the size of the roller and the shape of the groove, but if the rotation speed is too slow, the paste will not flow in an intermittent manner with certain impingements, and will not flow quickly. If it is too high, the effect of the grooves on the roller will be reduced, and the paste will flow evenly.

0 r, p, m, degree is the most effective. ``A paste-like active material causes non-uniform dispersion of active material particles, but according to the present invention, non-uniformity can be prevented by rotating the paste-like active material at high speed. ” Effects of the Invention As described above, the present invention provides a filling method for filling a porous body with a paste-like active material. By generating a constant flow rate and filling with the resulting pressure I, it is possible to uniformly fill the paste-like active material continuously and efficiently.Also, the roller does not come into contact with the porous body. Therefore, it does not wear out due to its high industrial value.
