らなる。2. Description of the Related Art In recent years, as a large-capacity stationary lead-acid battery of 100 AH / cell or more used for a backup power supply or the like,
Control valve type lead batteries have been widely used. Among them, a control valve-type lead battery using a mat-shaped separator made of fine glass fibers is subjected to pressure on the electrode group in order to improve various characteristics of the battery. In such a battery, it is necessary to increase the electrode plate size or increase the number of electrode plates constituting the electrode group as the capacity increases. For this reason, in the battery case for accommodating the electrode group, it is necessary to increase the dimension in the thickness direction of the electrode group (the laminating direction of the electrode plate and the separator), or the width dimension or the height dimension. Such a battery case is generally made of polypropylene, and is made of a rectangular parallelepiped with an open upper surface.

A battery case used for a stationary lead-acid battery or a liquid-type lead-acid battery having a large capacity of at least 00 AH / cell has a height dimension and a width dimension exceeding 200 mm and 120 mm, respectively. If such a container is left empty for a long period of time, it will be deformed. This deformation tends to be larger on the long side surface, and the deformation direction is often inward. Further, as described above, in the control valve type lead-acid battery, a pressure of 20 kg / dm 2 or more is generally applied to the electrode group, and a force is applied to the side of the battery case as a repulsive force of this pressure.
The battery case side deforms outward. Further, the side surface of the battery case in the direction in which the repulsive force of the tension is not applied is deformed inward.

In a control valve type lead storage battery, the battery is deformed by the repulsive force of the pressure applied to the pole group. When such deformation occurs, in the step of welding or bonding the battery case and the lid, the deformation of the battery case causes a displacement between the joining surfaces of the battery case and the lid, and in the worst case, there is a problem of causing poor airtightness. Was.
Further, even if the joint does not become defective at the time of manufacture, cracks may occur when the part with the insufficient joint is used for a long period of time, resulting in poor airtightness.

However, the former method has a disadvantage that the volume of the battery case material increases and the volumetric efficiency of the battery decreases. In addition, the latter means of providing reinforcing ribs has a drawback in the moldability of the battery case in addition to the former disadvantage.

An Ah (10-hour rate capacity) control valve-type sealed stationary lead-acid battery was manufactured up to the point where the electrode group was inserted into the battery case. Here, the battery case thickness is 5 mm, and the pressure applied to the electrode plate group is 40 kg / d.
m 2 . Next, these batteries (called comparative batteries)
A battery of the present invention having the same configuration as that of the first embodiment but provided with the support plate shown in FIG. 1 was manufactured. Here, the outer dimensions of the support plate 2 were 1 mm smaller than the inner dimensions of the battery case, and the thickness was 5 mm. This is because the support plate 2 can be easily accommodated between the battery case and the strap and the separator, and also a pressure is applied to the electrode group even when the battery case is not deformed.

きくなるほど顕著である。Using the above battery, the relationship between battery case width and strain was investigated. Here, the battery case width is the battery case wall dimension (mm) parallel to the electrode group of the investigated battery (perpendicular to the electrode plate surface of the electrode group), and the distortion is the cell size before deformation and the deformation inside the cell. It was investigated as a deviation (mm) of the same dimensions later. FIG. 4 shows the results. FIG.
It can be seen that the distortion of the battery case in the comparative product tends to increase as the battery case width increases. on the other hand,
It can be seen that the battery of the present invention has less distortion of the battery case than the comparative battery of the conventional structure. The effect is more remarkable as the battery case width increases.
