負極板を必要枚数組合せて極板群を構成していた。Conventional technologySealed lead-acid batteries have a structure in which the electrolyte is impregnated into a separator and is held in place.Also, the separator used for it has a position-free structure, so the most important feature of the separator used in it is its water retention capacity. . In order to take advantage of this feature, the separator is made of glass fiber that has a high water retention capacity of over 90%, and is designed to be as large as the size of the battery container allows in order to secure as much electrolyte as possible. ing. When assembling such a battery, in the process of assembling the separator and the electrode plate, conventionally, the separator is bent into a U-shape or an M-shape, and the electrode plate is attached to this bent part. So, the required number of positive electrode plates, separators, and negative electrode plates were combined to form an electrode plate group.

雑となり、生産性が悪くなる。Problems to be Solved by the Invention However, such electrode plates are simply wrapped with a separator, and it is difficult to ensure the positioning of the separator and the electrode plate.
< , a positional shift as shown in Fig. 1 occurred, which caused trouble in the next process. Furthermore, if an attempt is made to position the electrode plates in an irregular state, it will become mechanically complicated and productivity will deteriorate.

がある。In addition, in order to solve the above problem, there is a method of mechanically crimping the ends of the separators or using ultrasonic welding to form a bag and placing an electrode plate inside it, but the main component is glass fiber. The separator has a problem in that it is not possible to seal the separators together depending on the method described above.

ましい。Means for Solving the Problems In order to solve the above-mentioned problems, in the present invention, the separator mainly made of glass fiber and the electrode plate are made of acid-resistant and oxidation-resistant thermoplastic resin at both ends of the electrode plate or the electrode plate. The parts close to each other are integrated to form a composite electrode plate. This kind of composite electrode plate is made by applying molten acid-resistant and oxidation-resistant thermoplastic resin in a straight line to both ends of a separator mainly made of glass fiber, so that both ends or the vicinity of both ends of the electrode plate are coated with resin. It is preferable to align the electrode plates so that they are in contact with each other, fold the separator, wrap the electrode plate in a U-shape, and apply pressure to integrate the electrode plate.

るため、極板群構成時の生産性も著しく向上する。Function: With such a composite electrode plate, when combining alternately with counter electrode plates to form a group of electrode plates, as shown in Figure 2, it becomes easy to align the electrode plates with each other, and it is easy to remove the electrodes from the separator. There is no protrusion of the electrode plate, and there is no short circuit between live objects. In addition, it is possible to use a simple electrode plate group assembly machine that is commonly used in the past, which alternately combines plate-shaped separators and electrode plates.
Furthermore, instead of positioning the separator, the positive electrode plate, and the negative electrode plate, it is now necessary to position only the composite electrode plate and the counter electrode plate, so that the productivity when configuring the electrode plate group is significantly improved.

示す。A long separator is prepared by making paper from glass fiber by a papermaking method without using a binder or the like. At both left and right end portions of this separator 1, as shown in FIG.
Apply the melted polypropylene resin 5 using a 0.3-diameter nozzle, position the positive electrode plate on top of it in the proper position, and as shown in Figure 4, apply the positive electrode plate 2 with the separator 1 in a U-shape. The separator 1 and the positive electrode plate 2 were bonded and integrated by passing it between a pair of rollers 6 and applying pressure. FIG. 5 is a partially cutaway view of the obtained electrode plate. This composite electrode plate was combined with a well-known negative electrode plate, and the nominal voltage was 12V.
A sealed lead acid battery with a nominal capacity of 38 Ah was assembled. This battery and a battery using a conventional U-shaped separator,
Table 1 shows the results of comparing the performance at 20HR and 3HR.
表−１から明らかな通り、両者間に差はなかった。また

が向上することがわかった。As is clear from Table 1, there was no difference between the two. Also, when comparing the number of production per day in the electrode group construction machine,
It has been found that the present invention exhibits productivity that is approximately twice that of the conventional method, and that productivity is greatly improved.
上記実施例では、正極板をセパレータに包む形を示した
が、負極板を包む形にしてもほぼ同様の結果であった。In the above example, the positive electrode plate was wrapped in a separator, but almost the same results were obtained even if the negative electrode plate was wrapped.

が望ましい。The amount of resin applied for adhesion is determined by the diameter of the nozzle, but if the diameter is smaller than 0.1 m, the resin will not be able to be applied enough to achieve the desired adhesive strength. This resulted in a significant drop in productivity. Conversely, if the diameter exceeds 1.0 mm, the amount of coating will increase,
This poses a problem in use because it covers the parts of the electrode plate that are involved in the reaction, resulting in deterioration in production, especially in the 3HR performance. For these reasons, the nozzle diameter is 0.1 to 1.0 m.
is desirable.

物質の脱落も防止できる。Furthermore, in the above embodiments, the resin application position is on the inner side of both ends of the electrode plate, but in particular in an electrode plate that does not have frame ribs at both left and right ends, such as an expanded electrode plate, the resin application position is set to the inner side of the electrode plate. By using both the left and right ends, it is possible to integrate the active material and prevent the active material from falling off at the frame.
