The present invention relates to a method for manufacturing electrode plates for lead-acid batteries, and provides a paste-type lead-acid battery that can be mass-produced without impairing practical performance and has a conventional lattice body that is significantly lighter. . The lattice of a lead-acid battery has the functions of current collection and retention of active material. At present, grid bodies for automobile batteries are generally thin with a thickness of about 2 mm or less, and those with a crosspiece pitch P (square) of 4 to 8 mm as shown in FIG. 1 are generally used. In FIG. 1, A is a lattice frame, B is a lattice crosspiece, and C is an active material. Such a structure is more than sufficient as a current collector when considered from the functional aspect of the lattice described above, but if the crosspiece pitch P is made rougher than that, the raw paste may fall out of the lattice squares during filling or drip. This is because it is impossible to produce a good electrode plate due to the sagging bottom. The present invention improves the above-mentioned drawbacks of conventional grid bodies. Figures 2 and 3 each show an example of a composite lattice body obtained by the manufacturing method of the present invention. This is a lead-acid battery electrode plate in which active material C is filled into a composite lattice body that is integrated by applying agent E and pasting thin paper E. In addition, B is the crosspiece of the lattice. The composite lattice obtained by the manufacturing method of the present invention has frames on all four sides, and the thin paper is attached with a water-resistant adhesive, so even if the frame pitches are rough, the mechanical lattice body required when filling the green paste is The strength is sufficient, and the filled raw paste is supported by thin paper, so it does not fall out or drip. FIG. 4 shows a method for manufacturing a composite lattice body according to the present invention, in which A is a cast lattice feeder and B is an adhesive applicator. A lightweight lattice body a, in which the crosspiece pitches are conventionally cast roughly, is placed on a chain conveyor C from a feeder A and sent to a thin paper pasting process. There is an adhesive coating step in the middle of the chain conveyor C, and the surface of the grid body a comes into contact with a roller 1 coated with adhesive, and the adhesive is applied intermittently or continuously. The adhesive is applied to the roller 1 via the roller 2. The grid body coated with adhesive is then rolled onto tissue paper roll b.
After being brought into close contact with the thin paper E supplied by the presser roller 3, the thin paper is passed through a dryer D, and then separated one by one by a divider (cutting machine) E to obtain a composite lattice c of the present invention. Filling with the active material is performed from the other side to which the thin paper is pasted. Next, Table 1 shows a comparison of the battery performance of the electrode plate using the composite lattice of the present invention with that of a conventional product.

[Table] Compared to conventional products, the products of the present invention are superior in 5hR capacity. This is due to the fact that a large amount of active material was filled because the number of bars in the grid was small. In terms of high rate discharge performance, the reason why the discharge duration of the present invention using glass paper is particularly excellent is because the surface of the active material is disturbed by the glass fibers when filling the raw paste, increasing the porosity of the electrolyte. This is probably due to improved diffusion. Furthermore, it can be seen that even if the crosspiece pitch is made about four times as coarse, the function of the grid as a current collector is sufficient, and the voltage at 5 seconds is not inferior to that of the conventional product. The results are for the products of the present invention shown in Comparative Examples in Table 1 when applied to a positive electrode plate and a negative electrode plate. Since the active material of the negative electrode plate of a lead-acid battery is a good conductor, it can be easily inferred that even if the pitch of the bars of the grid is made even rougher, there is little deterioration in battery performance and there is no problem. The adhesive used in the present invention is one that firmly adheres the lead alloy grid and the thin paper, and it is not preferable to use an adhesive that reduces adhesive strength due to getting wet when filling the green paste or heating when drying the electrode plate. Furthermore, materials that elute harmful impurities during use in batteries are not preferred. Hotmelts (e.g. APP), acrylic acid or methacrylic acid ester based thermoplastic resins and styrene based thermoplastic resins and cyanoacrylate based resins, phenolic based resins such as resols and novolaks, epoxy based or polyester based thermosetting resins, rubber glues and asphalt. Compounds can be used as adhesives. Needless to say, it is important to apply the adhesive in such a way that the coverage of the crosspiece surface is minimized so as not to impair the current collecting function of the grid. Specifically, it is preferable to minimize the amount of adhesive used by devising the shape of the roller 1 and the shape of the bars of the grid in the adhesive application process. Among the adhesives mentioned above, acrylic acid or methacrylic acid ester emulsions and resols (water-soluble phenolic resins) are applied (transferred) to one side of a grid, then attached to thin paper and heated to 80 to 250°C. It solidifies in 1 to 2 minutes, making it particularly easy to work with. The mechanical strength of the lead alloy grid immediately after casting is weak. As mentioned above, heat treatment at 80 to 250°C during the thin paper pasting process accelerates the hardening of the alloy, so the resulting composite lattice has strong mechanical strength and is particularly convenient as it facilitates the subsequent green paste filling process. It is. As detailed above, the present invention applies a water-resistant adhesive to one side of a cast grid having a frame on all four sides,
This method of producing electrode plates for lead-acid batteries is characterized by filling an active material into a composite lattice formed by pasting thin paper mainly made of fibers, and allows for mass production without sacrificing practical performance. The present invention provides a paste-type lead-acid battery that is not limited to use only in thin automobile batteries, but is significantly lighter than the conventional lattice body, and has great industrial value.
