る。In the conventional electrode group a,
Since the anode plate 1 and the cathode plate 2 are simply in contact with the electrolytic solution holder 3, the active material is likely to fall off. Further, since the active material layers of the anode plate 1 and the cathode plate 2 are already in a solidified state during assembly, the bipolar plates 1 and 2 and the electrolyte solution holder 3 are
The adhesion between and is poor. On the other hand, in the conventional electrode plate group b, since the active material layers of the cathode plate unit 11 and the anode plate unit 12 are embedded in the thin electrolyte solution holder 14, the active material layer does not fall off. Although it can be prevented, there is a problem that the adhesiveness between the thin electrolyte solution holder 14 and the electrolyte solution holder 13 is poor. Deterioration of the adhesion between the thin electrolytic solution holder 14 and the electrolytic solution holder 13 hinders the movement of the electrolytic solution during charging, which causes a problem of reducing the discharge capacity and the cycle life. An object of the present invention is to provide an electrode plate group for a storage battery and a method for manufacturing the same that can solve the above problems.

いて、２１ａ及び２２ａはそれぞれ極板耳部である。FIG. 2 is a partially enlarged schematic view of the electrode plate group A. The main points of the method of manufacturing the electrode plate group A will be described below with reference to this drawing. First, one side surface of a grid (not shown) made of lead or a lead alloy is placed in contact with the electrolytic solution holder 23 made of a known glass fiber non-woven fabric. Then, a known active material paste is filled into the lattice portion of the lattice body from the other side surface side of the lattice body. The active material with which the grid body is filled penetrates from the surface of the electrolytic solution holder 23 to the inside through the holes formed in the grid body. Since the active material paste has a viscosity, the electrolytic solution holder 23
Permeates only to a certain depth in the thickness direction from the surface of. The portion where the active material paste has penetrated is the electrolytic solution holder 23.
Surface portion 23a. Next, before the active material paste dries, the next electrolytic solution holder 23 is placed in contact with the other side surface of the grid. At this time, it is preferable to apply a certain amount of pressure in the stacking direction so that the active material paste is also impregnated into the next electrolytic solution holder. Thereafter, the same process is repeated to stack the required number of electrode plates. After forming the electrode plate group, aging and drying are performed, and then group welding is performed to complete the electrode plate group. Each time one electrode plate is stacked on the electrolytic solution holder, the electrode plates may be stacked while the primary drying step is performed to primary dry the active material paste. In this way, the active material paste can be surely dried even when the electrode plate group is considerably multi-layered, and the electrode plates can be reliably positioned. The electrolyte solution can be injected into the electrolyte solution holder by using a technique such as vacuuming. In addition, in FIG. 2, 21a and 22a are electrode plate ear parts, respectively.

る。The electrode plate group B of FIG. 1 (B) is an electrode plate group except that the anode plate 22 of the electrode plate group A of FIG. 1 (A) is composed of a homopolar laminate type anode plate. Same as A. Therefore, in FIG. 1 (B), the same members as the members forming the electrode plate group A shown in FIG. 1 (A) are designated by adding 10 to the reference numbers shown in FIG. 1 (A). The description is omitted. The homopolar laminated type anode plate is formed by laminating a plurality of unit anode plates 32, 32 via a thin electrolyte solution holder 35, and forming each unit anode plate 32,
32 is connected to each other to form one anode plate. FIG. 3 shows an enlarged schematic view of the main part of FIG. When the unit anode plates 32, 32 are laminated, there is no problem even if the active materials are short-circuited inside the thin electrolyte solution holder 35. Therefore, the thickness of the thin electrolyte solution holder 35 is equal to the thickness of the electrolyte solution holder. It is thinner than 33. After stacking the electrode plate group B, the electrode plate ears 32a, 32a of the unit anode plates 32, 32 are connected to each other.
