る。 Expanded lattices are generally manufactured using an expanded system in which long and thin strips of lead alloy sheets are continuously expanded to form a lattice, which is then filled with an active material paste and then cut into individual electrode plates. When used, as shown in Fig. 1, compared to conventional cast lattices, there are no vertical frame frames on the left and right sides, and the lattice as a whole can easily deform. That is, the upper end of the grid ear part 1 is filled with active material paste to form an electrode plate, and when a plurality of anode plates are connected in parallel with a certain gap when forming an electrode plate group, a lead alloy is newly added thereto. A strap is made by welding them together by adding a . The batteries are inserted into the tank and the balls are fixed to the tank. Therefore, the terminal ear part 1 is fixed to the upper part, and the lower side of the electrode plate is fixed to the bottom part of the battery case. It will happen in the direction of the arrow. In this lattice, the anode active material (charge←discharge, PbO 2 →PbSO 4 ) expands and contracts as it charges and discharges. That is, if the volume of PbO 2 is 1, the volume of PbSO 4 will be approximately 1.9 times. We can roughly estimate the tension on the lattice due to the expansion and contraction of this active material.
1.7×10 -4 〜1.7×10 -3 Kg/mm 2 , which is a fairly small value for plastic deformation to occur, but this applies to cast grids with vertical frames, and as shown in Figure 1. It was experimentally confirmed that the expanded lattice deforms in the direction of the arrow in Figure 1 by repeating appropriate charge/discharge cycles. In addition, a battery with a capacity of 60Ah is installed in the taxi and used as a starting battery for approximately 100,000 yen.
Km, and as a result of one year of actual vehicle testing, the deformation amount reached approximately 8% in the height direction. Generally, the separator between the positive and negative electrode plates is installed from the top side of the plate to 4 to 6% of the height of the plate, but if it deforms to this extent, it will protrude above the top side of the separator, and the separator will be placed on the opposite side. The risk of contact with the ears of the cathode plate and short circuit increases. Furthermore, there are more opportunities for the upper shoulders of the elongated anode plate to come into contact with the lower surface of the strap to which the cathode plate group is welded. These two types of contact mentioned above are not caused by minute shots that occur when fine active materials come into contact, but rather the lattice itself comes into contact with each other, so that starting performance is almost instantaneously lost.

ある。 The present invention is intended to prevent such shots. That is, the deformation that occurs when an expanded grid is used for the anode plate occurs under extremely small tension, as mentioned above. Therefore, this can be sufficiently prevented by pressing both shoulders of the electrode plate. After filling the expanded grid with paste, it becomes an electrode plate through aging and drying, and a cell group consisting of anode and cathode plates is welded, and these cell groups are inserted into each cell chamber (generally 6 chambers) of the battery case. Connections are then made between each cell, and a lid is installed and secured to form a battery. The present invention attempts to achieve this objective by applying special features to the inside of the lid.

形しておけばよい。 The present invention will be explained using drawings. Figure 2 shows the capacity
FIG. 2 is a cutaway perspective view of the main parts of a 60Ah battery. The cell group consists of a cathode plate 2 using an expanded lattice, a bag-shaped separator 3 into which it can be inserted, an anode plate 4 using an expanded lattice, and each strap 5 (for cathode), 6
(For anode) Each ear part 7, 1 is welded. 8 is a battery case. For example, if the anode plate 4 deforms like the shoulders shown in FIG. 1, the deformed portion comes into contact with the cathode ear 7 and furthermore the cathode strap 5, as described above, and generates a shot. In order to prevent this, both shoulders of the anode plate 4 may be held down by some means. In this invention, this role is
Pressing plates for both shoulders of the anode plate are integrally molded in advance on the inside of the lid that is fixed on top of the battery case shown in the figure, and at the same time when this lid is integrated with the battery case, the holding plates are attached to both shoulders of the anode plate. The upper separator is fitted with a lid having a structure that presses the upper end of the upper separator slightly. In this case, the effect is almost the same even if only the shoulder of the anode plate 4 where the cathode strap 5 is located is pressed instead of both shoulders. An example of the inside of the lid is shown in Figure 3.
As shown in the figure. 9-1 to 9-6, 10-1 to 10 in the figure
-6 is the holding plate on both shoulders of the anode plate. For only the shoulder on the cathode plate strap side, use 9-1, 9-3, 9.

ある。 In addition, in FIG. 3, 11 is a lid. However, in this case, some problems occur. That is, the upper part of the anode plate 4 is connected to the presser plates 9-1 to 9- on the inside of the lid 11.
6 and 10-1 to 10-6 and the electrode plate ears 1 and 7 are fixed with straps 5 and 6, and the bottom of the anode plate 4 is attached to the bottom of the battery case (if there is no clamp) or by the clamp. Since it is fixed, if the anode plate 4 is slightly stretched, it may deform in a wavy manner. Although it depends on the severity, if it is severe, it may lead to the anode active material falling off, and even if it occurs only a little, it may cause minute cracks at the interface between the ossicles and the active material. In order to eliminate such problems, the present invention provides a holding plate on the inside of the lid, and at the same time, when forming a cell group with positive and negative electrode plates and separators, the height of the anode plate 12 is adjusted as shown in Fig. 4. An average of 8% of the height of the cathode plate 2 (4~
12%) and the reduced dimension is provided as an extension 13 below the cathode plate 12, and the anode plate 1

2 was deformed downward without any upward deformation, but since there was an elongation margin 13, it was absorbed into the elongation, and a short circuit between the negative and anode plates 2 and 12 due to the elongation of the anode plate 12 occurred. There were none.
