Description of the Related Art A battery having a structure in which a strip-shaped positive electrode plate and a negative electrode plate are wound in a spiral shape via a strip-shaped separator has a structure in which an electrode plate group is strongly pressed and wound, It is not necessary for the electrode plate itself to have strength for supporting the electrode plate group, unlike a battery produced by laminating an electrode plate and a separator, and a very thin electrode plate can be used. Therefore, the surface area of the electrode plate is large, and the active material utilization rate and voltage characteristics are excellent. However, a cylindrical void was formed in the central portion, and the volume of that portion could not be effectively utilized.

欠点があった。Further, although the spiral-shaped battery has excellent voltage characteristics in a single cell, when these are combined to form a high voltage, the cells must be connected to each other, and the voltage due to the ohmic loss at the inter-cell connecting portion is required. There was a drawback that the loss became large.

It also has a drawback that the material utilization rate is lowered and it is difficult to obtain a large capacity battery.

9), a specific amount of sulfuric acid having a specific gravity was injected into each cell. In order to improve the liquid injection property, holes 20 were opened in the collector portion above the cell of the electrode plate. After the sulfuric acid injection was completed, the solution was allowed to stand for about 1 hour to allow the liquid to permeate the active material, and then charged for chemical conversion. Since the gas generated at the time of charging was discharged from the liquid injection port 19, the battery did not swell and good formation was possible. After the formation was completed, the valve seat 21 was firmly attached to the injection port, and the valve 22 was attached.
