も強いという特長も有している。Configuration of conventional example and its problems In a sealed lead-acid battery, a plate-shaped positive electrode and a negative electrode are alternately stacked with a separator interposed therebetween, and a strip-shaped positive electrode plate and a negative electrode plate are interposed between them. There is something that is wound in a spiral with interposition. In the latter spiral lead-acid battery, a thin electrode plate is spirally wound at a high group pressure to form a cylindrical electrode plate group, whereby a battery having excellent life characteristics and rapid discharge characteristics can be manufactured. In addition, because it is cylindrical, it also has the advantage of being resistant to external impact.
以下に従来の渦巻式鉛蓄電池について説明する。The conventional spiral lead-acid battery will be described below.

Since the separator is wound so as to be thin and has a high group pressure as described above, the electrolyte may permeate through the safety valve hole 6 at a low rate of permeation of the electrolytic solution into the separator. In addition, the electrolytic solution or the mist of the electrolytic solution may leak from between the safety valve 5 and the hole 6 even in the chemical conversion process.
It had a big problem that it corrodes.

For No. 3, the specific gravity was adjusted to 1.25 so that the liquid surface was at the height of the electrode plate group. The above-prepared batteries were immersed in 50 sulfuric acid tanks at a time for injection. The time required for injection was about 1 minute. The separator was able to retain 20 c.c. of sulfuric acid. With this battery immersed in the sulfuric acid tank 12, formation was carried out at a constant current of 0.1 CA for 20 hours. After that, as shown in FIG. 3, the sulfuric acid tank 12 was pulled up, excess liquid was discarded, and the air holes 10 in the upper lid 8 were closed by heat welding to leave no holes. The safety valve 11 is installed in the safety valve hole 9 of the battery case 7.
Was inserted to prepare a battery A. For comparison, 50 batteries were prepared by injecting sulfuric acid with the conventional nozzle shown in FIG. The injection method is as follows:
Using a nozzle having an inner diameter of 1.5 mm, the injection amount was 20 c.c. and the injection time was 1 minute. As a result of injection by this method, 5
Six of the 0 pieces overflowed and sulfuric acid adhered to the terminals. Similar to Battery A, 50 of these batteries were subjected to formation at a constant current of 0.1 CA for 20 hours to form Battery B.

た。A total of 100 of these A and B batteries were left for one week and checked for capacity inspection and terminal corrosion. As a result, there was no difference in capacity between the batteries A and B. However, in battery B, terminal corrosion was observed in 9 out of 50 cells, and sulfuric acid overflowing from safety valve 5 and safety valve hole 6 adhered to terminal 4 during formation,
It is considered that corrosion has occurred. On the other hand, sulfuric acid did not adhere to the terminals of the battery A of the present invention and no corrosion was observed.

In the present embodiment, 50 pieces were injected at the same time, but the larger the sulfuric acid tank, the larger quantity of cells can be injected at one time. That is, by providing the hole for the liquid injection and safety valve in the bottom portion, the electrolytic solution can be quickly injected into the battery case, the workability of assembling the battery is improved, and the mass production is facilitated.
