Batteries were manufactured by filling the battery with a group of electrode plates, fixing the cover with a safety valve to the casing by adhesion or welding.

厚を極端に薄くすることは困難であった。Problems to be Solved by the Invention In such conventional configurations, the casing is manufactured by molding or bonding, so there is a problem that it is difficult to manufacture a thin casing. To explain in more detail, the development of electronics technology has been remarkable in recent years, and in connection with social demands, electronic devices have become increasingly lighter, thinner, shorter and smaller. These electronic devices necessarily require a power source, and there is a strong demand for this power source to be lighter, thinner, and smaller. Among these, there is a particularly strong demand for thinning. In order to meet such demands, batteries must be made thinner and thinner, but it has been difficult to make them thinner with conventional technology. That is, in molding, it has been difficult to make the wall thickness extremely thin in terms of the strength of the core or the dimensional accuracy of the molded product, and also due to the amount of water vapor permeation of the material, whether it is a molded product or a bonded product.

る。Means for Solving the Problem In order to solve this problem, the present invention has a water vapor permeability equal to or lower than that of the conventional molded casing, that is, 5 y/m'724.
In a lead-acid battery having a structure in which positive and negative electrode plates, a separator, and an electrolyte are filled in a synthetic resin film bag having a water vapor permeability of less than 1 hour, the safety valve part is preferably made of the same material as the film bag, such as polyester-polyester. Vinylidene chloride
A film bag is used, which has a safety valve part made of a laminated film of ethylene acrylic acid copolymer film, an unsealed part in only one direction of the bag, and a hole through which the positive and negative poles pass. Open the unsealed part of the film, insert the electrode plate group from here, and pass the positive and negative pole poles into the pole pole penetration holes of the film, so that this part is airtight.
The space between the film bag and the pole is sealed, and then a specified amount of sulfuric acid of a specified specific gravity is injected from the unsealed area, and the unsealed area is left as it is or a part of the unsealed area is sealed. It is something to do. More preferably, in order to achieve more complete airtightness between the pole and the film bag, a pole whose surface is coated with a resin in advance is used.
作 用
このような構成により、従来達成困難であった薄形鉛蓄

電池において、フィルム製袋と同材質の安全弁部が製作

来の合成樹脂製筐体と同程度であるため、材質が薄くて
も電解液の逸散が少ないこと、フィルムと極柱との間の
気密性が確保でき、気密漏れ、液漏れが防止できること
、フィルム製袋の製法が従来の筐体製法に比較して簡単
であることなど製法が簡略できることになる。Function: With this configuration, it is possible to manufacture thin lead-acid batteries, which was difficult to achieve in the past.Furthermore, in lead-acid batteries with this configuration, the safety valve part can be manufactured from the same material as the film bag, and the manufacturing method has been improved. In addition, in the production of lead-acid batteries, there is no need to install a safety valve in a separate process, which reduces the number of man-hours, and the water vapor permeability of 7゛Im is comparable to that of conventional synthetic resin casings. Therefore, even if the material is thin, there is little electrolyte dissipation, the airtightness between the film and the pole can be ensured, and airtight leakage and liquid leakage can be prevented. The manufacturing method can be simplified because it is simpler than the body manufacturing method.
さらに電池が増々軽薄短小化され、しかも工程合理化の
ため従来の極板化成法から電槽化成法になりつつあるこ

入できず、多量の電解液を必要とする電槽化成が不可能
となる欠点が、フィルム製袋でその長さが自由に制御で
きる本発明法においては解決できることとなる。Furthermore, as batteries are becoming increasingly lighter, thinner, shorter, and smaller, and in order to streamline the process, the conventional electrode plate formation method is being replaced by a battery case formation method, making it difficult to secure a large space above the electrode plate group in the conventional battery structure. This makes it impossible to inject a large amount of electrolyte and makes it impossible to form a battery case, which requires a large amount of electrolyte. This can be resolved.
さらに電槽化成時に安全弁部からガスや電解液の飛沫を
通さない本発明方法では、安全弁部の変形や老化が抑制
でき、安全弁部の信頼性を向上することもできる。Furthermore, in the method of the present invention, which does not allow gas or electrolyte droplets to pass through the safety valve part during battery cell formation, deformation and aging of the safety valve part can be suppressed, and the reliability of the safety valve part can also be improved.

In the example, a pole was used in which the lead alloy surface was coated with an epoxy resin that had good adhesion to metals, and the pole was coated with an ethylene acrylic acid copolymer made of the same material as the film-making bag that was in contact with the pole.

Because this battery uses a chemically-contained container to streamline the process, it requires a larger amount of electrolyte than when using conventional chemically-contained electrode plates, but since the bag size can be increased, the amount of wet liquid Can be injected without any formation. This battery was formed into a container, and the unsealed portions were then sealed to complete the battery.
