電解液の侵入しにく−なる不都合をもたらす。In addition, when the strip-shaped anode plate and the strip-shaped cathode plate are each bent in a zigzag shape during the manufacturing process, the active material filled in the strip-shaped lattice substrate can be easily removed from the substrate at each bent portion of each strip-shaped plate. However, it is difficult to produce high-quality products because of the inconvenience of peeling and falling off. This inconvenience often occurs especially when an expanded grating substrate is used. In this case, it is conceivable to attach strips of paper to both sides of each strip-shaped electrode plate before the bending process to prevent the active material from falling off at the bending part during bending. The work of pasting paper on both sides of the plate is troublesome and takes a considerable amount of time, and there are also disadvantages in that it is difficult for the electrolyte to penetrate into the strip-shaped electrode plate.

This invention provides a foldable electrode plate group for a storage battery, which is made by folding a band-shaped electrode plate group consisting of a band-shaped anode plate and a band-shaped cathode plate polymerized with a band-shaped separator in between in a zigzag shape. Each folded portion of the strip-shaped anode plate folded in a zigzag shape and each folded portion of the strip-shaped cathode plate is provided with a cut for cutting the respective strip-shaped active material lattice substrate.

を交互に重畳せしめるようにしたことを特徴とする。Furthermore, the present invention provides an electrode plate group having the following formula: ":" can be formed well without the filled active material falling off at the folded portion, and the electrolyte can penetrate well, and the folded strip separators can be alternately stacked on top of each other. The present invention provides a method for manufacturing a foldable electrode plate group for a storage battery, which can be easily aligned with negative and anode plate parts, and can be properly accommodated in a battery container. A strip-shaped electrode formed by polymerizing a strip-shaped anode plate made of a paste-like anode active material filled and coated and a strip-shaped cathode plate made of a strip-shaped grid substrate filled and coated with a paste-shaped II electrode active material through a strip-shaped separator. Before folding the plate group into a zigzag shape, in advance, each of the strip-shaped anode plate and the strip-shaped cathode plate is folded in a zigzag shape at regular intervals, so that at least one side edge of each active material-filled grid substrate is attached. Then, by bending the band-shaped electrode plate group in a zigzag shape at the cut portion, the IJR end cut by the cut is made with each flat plate portion of the band-shaped separator bent in the zigzag shape. It is characterized in that an anode plate portion and a cathode plate portion having edges are alternately overlapped.

性の向上した安定良好な電池をもたらす。In the above electrode plate group of the present invention, both side edges of the cathode plate part and the anode plate part which overlap with each other through the flat plate part of the zigzag band-shaped separator are cut edges formed by notches.
This cut edge allows the electrolyte to easily enter the electrode plate.
The utilization rate of active materials can be improved. In addition, because the adjacent electrode plate parts are separated from each other by the notches provided at predetermined intervals in the strip-shaped electrode plate, it is possible to easily align the overlapping negative and anode plate parts through the separator bent in a zigzag shape. , and the separator as a whole is obtained as a foldable electrode plate group that does not displace to the left or right, and can be easily and efficiently assembled into a battery container. In addition, in the method for manufacturing the electrode plate group described above, incisions are made in advance in each of the band-shaped anode plate and the band-shaped cathode plate at the portions to be bent. In addition, each strip-shaped electrode plate bent in a zigzag shape is correctly aligned with the negative and anode plates in each flat plate part of the strip-shaped separator bent in a zigzag shape. In this case, when the filling active material of the strip anode plate and the filling active material of the strip cathode plate are folded through the strip separator in a zigzag shape before drying, the parts can be aligned and polymerized, resulting in a high quality product. The two electrode plates of the same polarity, which are polymerized back to back in each 0-shaped valley space of the zigzag band-shaped separator, adhere to each other at the mating surfaces due to the viscosity of the active material, and after subsequent drying, , - A stable battery with improved earthquake resistance that is bonded to the body and does not shift relative to each other even when subjected to shocks, vibrations, etc., and is housed in a battery container and maintains a predetermined correct polymerization state under its usage conditions.

群Ｎが得られる。According to the present invention, the band-shaped anode plate 1 and the band-shaped cathode plate 2 are superposed via the band-shaped separator 3 to form a band-shaped electrode plate group A.
Next, when folding this in a zigzag shape to produce a foldable electrode plate group for a storage battery, in advance, each of the strip-shaped anode plate 1 and the strip-shaped cathode plate 2 is folded in a zigzag shape at a predetermined constant interval on the left and right sides. Cuts 4 are provided in portions that are scheduled to be alternately bent so as to cut the band-shaped lattice substrates 1a, 2a of the respective electrode plates 1, 2. In the illustrated case, the cut 4 extends over the entire width of the internal grid plate area in each of the strip-shaped substrates 1a and 2a, leaving the upper and lower edges 1c, Ic, 2c, and 2c. ,2C1
Alternatively, the cut 4 may be a cut that cuts one side edge of the lower edge 1c, 2c while leaving either one of the lower edges 1c and 2c.The cut 4 may be a cut line with almost no width, and may be a cut line with a minimum width of 1 cut, but generally, it is 2 to 2 cm wide. It is preferable to have a relatively wide slit shape of about 6 mm. According to this, when the strip-shaped electrode plate group A is folded in a zigzag shape as shown in FIGS. 2 and 3, each strip-shaped electrode plate 1 Or 2 is bent alternately on the left and right sides, but the notches 4 are pre-drilled in the bent portions, so that the active material at each bent portion of the conventional strip-shaped anode plate and strip-shaped cathode plate that are not provided with the notches 4 is Not only does it not come off at all, but each bent portion has longitudinal notches 4, which makes it easy to bend each strip-shaped anode plate 1 or 2, and the strip-shaped anode plate defined between the notches 4. Each anode plate part 18 of 1 and each cathode plate part 2^ of the strip-shaped cathode plate 2
can be relatively freely positioned by sandwiching the flat plate part 3^ of the band-shaped separator 3 bent in a zigzag shape and aligning and overlapping them at the correct position on both sides of the flat plate part 3^, so that the left and right bent parts are aligned in a straight line as a whole. A properly arranged group of folded electrode plates N can be obtained.

By bending it in a zigzag shape, valley spaces of 0 characters are formed alternately on the left and right sides, and inside each of them,
Two laminated anode plates IA, 14 and two laminated cathode plates 2A, 2A are alternately housed, but in the manufacturing process, the filling active material of the strip-shaped anode plate 1 is 1b and the filling active material 2b of its strip-shaped cathode plate 2,
When folding the electrode plate group A in a zigzag shape before heating and drying, that is, in a wet and viscous undried state,
These two anode plates 7A and IA and the two cathode plates 2A and 2A in the WIN state adhere to each other on their opposing polymerized surfaces due to their viscosity, so during subsequent heating drying, Both are dried and solidified in close contact with each other.
