る必要があつた。 A monoblock lead-acid battery uses a bipolar plate structure in which a positive electrode plate is connected to one side of a conductive plate made of lead or the like, and a negative electrode plate is connected to the other side. It has already been proposed for purposes such as making batteries more compact. The structure of this bipolar plate is as shown in Figure 1a, where 1 is a lead plate and 2 is a lead plate.
is a positive electrode plate, and 3 is a negative electrode plate, and the lead plate 1 and the positive electrode plate 2 or the lead plate 1 and the negative electrode plate 3 are electrically joined. However, since the lead in contact with the positive electrode plate undergoes anodic oxidation and gradually corrodes, when used as a partition wall, a thickness l is required that corresponds to the expected lifespan, which has the disadvantage of making the battery heavier. In particular, pure lead and lead-calcium lead alloys tend to undergo corrosion along grain boundaries, so it is necessary to increase the thickness sufficiently.

A so-called partially conductive plastic plate having a structure in which 6' is crimped onto a plastic plate 4 has been proposed. Although this is effective in reducing weight, it has the disadvantage that the lead collars 6, 6' must have a considerable size in order to prevent liquid leakage through the holes 5 of the plastic plate 4, making it difficult to downsize. However, it was difficult to apply it to small batteries.

In this method, an opening exposed from the plastic plate is provided, and a bipolar plate is used in which a positive electrode plate is connected to one side of the opening and a negative electrode plate is connected to the other side.

On the other side, openings 10 are provided at locations that do not face each other. Further, the lead material plate 7 may be provided with a plurality of holes. This is not only effective in reducing the weight of the lead material plate 7, but if the hole is filled with plastic that is integrated with the plastic plate 8, the lead material plate 7 and the plastic plate 8 can be separated. This has the advantage of making the bond stronger. 1

However, in the embodiment of the present invention, a short circuit occurs only after the corrosion has progressed by the distance m between the openings on both sides of the lead material plate 7. Therefore, as long as the distance m is made large, even if the thickness of the lead material plate 7 is made small, the period until a short circuit occurs can be lengthened, that is, the life can be extended.
