い。Means for Solving the Problems In order to solve the above problems, the present invention mainly comprises an electrode plate using a lattice body having no frame at both left and right ends and glass fibers wrapping the electrode plate in a U-shape. With a separator,
The width of the separator is larger than the width of the electrode plate, and the electrode plate and the separator are bonded by a thermoplastic resin at least at both left and right ends of the electrode plate. In such a composite electrode plate, a molten acid-resistant and oxidation-resistant molten thermoplastic resin is linearly applied to both ends of a separator mainly composed of glass fibers, and both ends of the electrode plate or the vicinity of both ends are made of resin. It is preferable that the electrodes are aligned so as to be in contact with each other, the separator is bent, and the electrode plates are wrapped in a U-shape to be integrated by pressing.

There is no protrusion of the electrode plate, and there is no short circuit between the active materials. In addition, it is possible to use a simple electrode plate assembling machine generally used in the past, which alternately combines a plate-shaped separator and an electrode plate. Since only the positioning of the two electrodes, the electrode plate and the counter electrode, is sufficient, the productivity in forming the electrode plate group is also significantly improved.

ことがわかった。Glass fiber is made by a papermaking method without using a binder or the like to prepare a long separator. As shown in FIG. 3, a polypropylene resin 5 melted at 170 ° C. is applied to both left and right end portions of the separator 1 with a nozzle having a diameter of 0.3 mm, and a positive electrode plate is positioned on a regular place thereon.
As shown in FIG. 4, while wrapping the positive electrode plate 2 in a U-shape with the separator 1, it was passed through a pair of rollers 6 and pressed to bond and integrate the separator 1 and the positive electrode plate 2 together. Fifth
The figure is a diagram in which a part of the obtained electrode plate is broken. This composite electrode plate was combined with a known negative electrode plate to assemble a sealed lead-acid battery having a nominal voltage of 12 V and a nominal capacity of 38 Ah. This battery and a battery using a conventional U-shaped separator are combined with 20HR and
Table 1 shows the results of performance comparison at 3HR. As is clear from Table 1, there was no difference between the two. Also, comparing the number of productions per day in the electrode group constituting machine, it was found that the present invention showed about twice the productivity as compared with the conventional one, and the productivity was greatly improved.

しい。 In the above embodiment, the shape in which the positive electrode plate is wrapped in the separator is shown, but the same result is obtained when the shape in which the negative electrode plate is wrapped is used. The application amount of the resin for adhesion is determined by the nozzle diameter, but if the diameter is smaller than 0.1 mm, the resin is difficult to be discharged, and a sufficient application amount cannot be provided, so that a predetermined adhesive strength cannot be obtained, Productivity dropped significantly. Conversely, if the diameter exceeds 1.0 mm, the amount of application increases, and the reaction-relevant portion of the electrode plate is covered, which causes a problem in use because production is deteriorated, particularly, 3HR performance is significantly reduced. For these reasons, the nozzle diameter is desirably 0.1 to 1.0 mm.

活物質の脱落も防止できる。Further, in the above embodiment, the application position of the resin is located on the inner side from both ends of the electrode plate. In particular, in an electrode plate having no frame at both left and right ends, such as an expanded electrode plate, the application position is set to the electrode plate. With the left and right ends, the active material in the frame can be prevented from falling off at the same time as the integration.

There is no displacement of the separator, a short circuit of the active material can be prevented, and the battery quality can be significantly improved.
