It was manufactured by being housed in a plastic electrical case.

９５８級
号公聯、特開昭６０−２３０３５４号公報）。Problems to be Solved by the Invention In recent years, devices using sealed lead-acid batteries have become smaller and smaller, and batteries are increasingly required to be lighter, smaller, and thinner. In order to meet these demands, we developed a third layer that wraps the electrode plate group with a laminate film or sheet with low moisture permeability.
The structure shown in the figure has been proposed (Japanese Unexamined Patent Publication No. 60-205
958-class Public Union, Japanese Patent Application Laid-Open No. 60-230354).

圧する構造を得んとするものである。However, in order to take advantage of the features of being lightweight, compact, and thin, the case must be designed to be as thin as possible. As a result, in the case housing the storage battery, the center of the electrode plate group is deformed into a slightly bulging shape, and there is a problem in that the pressurization at the center is insufficient and the performance as a storage battery is impaired. To solve this problem, conventionally, as shown in Figure 4, a foamable synthetic resin such as urethane foam (hereinafter referred to as "sponge") was housed inside the case along with the storage battery, and the elasticity of the sponge allowed the center of the electrode plate group to A method was adopted to compensate for the decrease in pressurization. This requires the sponge to be prepared as a separate component when assembling the battery, which poses problems such as difficulty in automating battery assembly. The present invention aims to eliminate the above-mentioned problems and provide a structure that can satisfactorily pressurize the electrode plate group without using a separate component such as a sponge.

。FIG. 3 shows a conventional proposal disclosed in the above-mentioned Japanese Patent Laid-Open No. 60-205958. The electrode plate group is wrapped with two laminate films 10 and the periphery is welded. Such a storage battery is housed in a rigid case 11 as shown in FIG. 4 in order to pressurize the electrode plate group. At this time, since the center of the case 11 is deformed into a slightly bulging shape, the pressure applied to the center of the electrode plate group becomes small, so the sponge 12 is inserted and pressure is applied by the elasticity of the sponge 12.
本発明の蓄電池を第１図、第２図に示す。The storage battery of the present invention is shown in FIGS. 1 and 2.

キャップ１に溶着して蓄電池を構成する。The positive and negative electrode terminals 2.2' are embedded, and the synthetic resin cap 1 and the electrode plate group 6 with the safety valve 4 are connected to the positive and negative electrode ears 7.7'.
Then, the electrode plate group 6 is connected by a method such as welding, and the electrode plate group 6 is wrapped in a laminated film bag 8, and the bag 8 is welded to the cap 1 to form a storage battery.
このとき袋８の溶着耳部１３は極板群の略中央にあるが
、やや片側（第１図ではやや右側）に寄せてあり、この
溶着耳部１３を極板群の中央寄りの側（第１図では左側
）へ折曲げた状態でケース１１に収納する。At this time, the welding ear 13 of the bag 8 is located approximately at the center of the electrode plate group, but it is moved slightly to one side (slightly to the right in FIG. 1); It is stored in the case 11 in a state where it is bent to the left (in FIG. 1).

易になり、工業的価値は極めて大である。A cross section when stored in the case 11 is shown in FIG. In addition, in the drawing, 5 is an upper lid placed on the safety valve 4;
3 is the exhaust part and 9 is the welded part to prevent that drop,
In the storage battery of the present invention, the welded ears of the laminate film can provide an effect with less variation in pressurization, so a sponge is not necessary. This reduces costs, eliminates the need to handle soft objects such as sponges, improves productivity, and facilitates the automation of battery assembly work, which is of great industrial value.
