When covering some of the connected lattice bone parts with a lead or lead alloy thin film, remove the surrounding bone to form a lattice so that the lattice will not be blocked by the lead or lead alloy thin film. The purpose is to cut out a part of the active material supporting bone to improve the filling of the active material and the diffusivity of the electrolyte.

薄膜６が形成される問題があつた。 Various proposals have been made to reduce the cost and weight of lattice bodies, and composite lattice bodies made of a combination of lead or lead alloy and synthetic resin are known. As a known example of such a composite lattice body, as shown in FIG. 3, a part of the lattice bones including the ears 2 of the lattice structure 1 molded from acid-resistant synthetic resin and connected thereto are made of lead or Some are coated with lead alloy. The lattice structure shown in FIG. 3 is made of, for example, polypropylene, and the surrounding bones 4 that are directly connected to the ears 2 are active material supporting bones that form inner lattices and hold the paste-like active material. It is formed thicker than 5. Note that the active material supporting bones 5 are usually formed in a staggered manner with respect to the surrounding bones, and care is taken so that the continuity of the filled paste-like active material is not interrupted due to the formation of lattices. ing. Of such a lattice structure, at least some of the lattice bones connected thereto, including the ears 2, are immersed in molten lead or a lead alloy, or the molten lead, etc. is poured onto the lattice structure to remove lead or lead. When applying the alloy coating 3, since the lattice openings are secured as well as the lattice bone surface, an unnecessary thin film 6 of lead or lead alloy is applied to cover the lattice openings due to the surface tension of the molten lead or lead alloy. There was a problem that was formed.

A portion 7 of the active material supporting ribs 5 forming the lattice has a notch, and then the lattice structure 1 is immersed in molten lead or a lead alloy with the ears 2 facing downward, or is melted into the molten lead or lead alloy. For a lead-acid battery, the active material support bone 5, the surrounding bone 4, and the ear portion 2, in which the portion 7 has been cut out, are continuously coated 3 with lead or a lead alloy by pouring lead or a lead alloy. This is a method for manufacturing a lattice body.

を流しかければよい。 FIG. 1 shows a lattice structure 1 molded from polypropylene or the like, similar to the conventional example described above, in which ears 2 and surrounding bones 4 are integrally formed, and the surrounding bones 4 are formed integrally with each other.
At the same time, a part 7 of the active material support bone 5 forming a part of the lattice close to the ears 2 is cut out to intentionally create an incomplete lattice. Using such a lattice structure, the active material can be supported in the incomplete portions of the lattice as shown in Figure 2 by dipping or pouring it into molten lead or lead alloy with the ears 2 facing downward. The bone 5, the surrounding bone 4 and the ear 2 are continuously coated 3 with lead or a lead alloy. During this coating process, the ear portion 2
Since the lattice meshes close to the active material support bones 7 are cut out and do not form a complete lattice mesh pattern, the lattice meshes are closed with a thin film 6 of molten lead or lead alloy as in the conventional case. Therefore, it is possible to improve the filling of the paste-like active material and the diffusion of the electrolyte. In addition, since this grid body is connected to a pole pole or another pole plate of the same polarity at its ears 2,
It is preferable that the lead or lead alloy coating on the ears be thicker than on other parts, and for this purpose, the ears or the ears and their vicinity should be immersed in molten lead or lead alloy several times, or the ears should be immersed several times in the molten lead or lead alloy. All you have to do is pour molten lead or lead alloy over the area.

However, in the present invention, there is room for weight reduction and cost reduction as a lattice body, and in order to further improve current collection efficiency, notches are provided in the active material supporting bones forming all lattice holes, and lead or lead or The entire lattice frame can also be covered with lead or a lead alloy thin film to prevent the lead alloy thin film from stretching.
