兼用の微孔シートを配してなるものが提案されている。Conventional technology and its problems In the past, in small sealed storage batteries, etc., in order to effectively utilize the space inside the battery case, a battery was used that was large enough to fit the pole plate to the bottom of the battery case, excluding the saddle for supporting the plate at the bottom of the battery case. Satoshi,
In order to prevent short circuits caused by fallen active material, it has been proposed that a microporous sheet that also serves as a separator is placed at the bottom of the electrode plate.

As shown in Japanese Patent No. 05, there is a storage battery in which positive and negative electrode plates are alternately interposed between the upper openings of a series of microporous sheets folded in the vertical direction. However, in order to manufacture a storage battery with this structure, it is necessary to insert the electrode plates into openings at certain positions on the top of a series of perforated sheets that are folded in the vertical direction and stack them, resulting in low production efficiency. There is. Moreover, once the failure ρ occurs, self-recovery is impossible, and it is necessary to stop the production machine every time to remove defective products from the laminated portion, which has the disadvantage of low productivity.

であった。Another proposal is to laminate U-shaped hole sheets with electrode plates interposed between them.1 However, with this structure, the electrode plates move during stacking and short circuits occur on the sides. There were drawbacks, such as the need for a special process of fixing with adhesive or the like.

からなる。なお、1dは折り曲げ部である。The hole sheet 1 is made by cutting a regular sheet or a continuous sheet with an independent stay V-tsun and cutting the hole sheet into a regular shape. It is formed by bending it in one direction to a size that can accommodate the Huikong Sheet 1
For example, it is made mainly of glass fibers with a fiber diameter of 1 pm or less, to which glass fibers with a fiber diameter of 1 P awn or more and a very small amount of organic fibrous material are added, and the glass fibers with a fiber diameter of 10 to 30 μm are added. Made of materials that contain. Note that 1d is a bent portion.

FIG. 2 is a partially cutaway front view of the storage battery of the present invention. In addition, 5 is a negative electrode plate stopper, 6 is a container lid, 3' is a negative electrode plate lug, and 4' is a positive electrode plate lug.

。The effect of the invention is positive. The negative electrode plate 3.4 is housed in the recess of the microporous sheet 1 having the folded portion 1d, and is restrained by the edge of the folded portion 1d of the micropore V-}1. } 1 and adjacent positive. Since the ends of the negative electrode plates 3 and 4 are not exposed beyond the microporous seam 1, short circuits can be prevented. The coffin board accommodated in the recess of the microhole V-}1 having the bent portion 1d is restrained by the edge of the bent portion 1d, so the inertia during conveyance after lamination causes the microhole V-} 1, the negative electrode plate 3, the positive electrode plate 4, and the microporous sheet 1 can be combined to form a layered layer system using the two-seven-a-machine method, which facilitates continuous production and improves work efficiency. The improvement can be measured. Further, the microporous sheet 1, positive. negative electrode plate 3,
Even if after MMing 4 as specified, the edge protruding from the periphery of the electrode plate is bent in one direction except for one side on the edge side of the electrode plate, it will not work properly. The negative electrode plate 3.4 has the micropores V-
} Since it is restrained by the green part of the folded part 1d of 1, it is effective in preventing the end of the electrode plate from being exposed against the inertial force during transportation.
