Abstract

PURPOSE:To increase discharge performance and life and obtain a structure suitable for mass-production by arranging an aluminum layer inside a film- or sheet-like synthetic resin. CONSTITUTION:A film-like synthetic resin is formed by interposing an aluminum layer 1 between polyethylene resin layers 2 and placing a polyester resin layer 3 on one side of polyethylene layer 2. The thickness of the aluminum layer 1 is limited to 5mu or more in terms of moisture permeability and 50mu or less in terms of increase in thickness. A plate group comprising one cathode plate 4, two anode plates 5, and a glass mat retainer 6 is placed between the film-like synthetic resin and the circumference of the synthetic resin is heat-pressed to form a battery container. Battery terminals are formed in such a way that lead wires covered with polyethylene resin are welded to the electrode plate, and the covered parts of the lead wires are placed between the film-like synthetic resin and melt-bonded and the lead wires are drawn out from the battery. A safety vent is formed jointly with the film like synthetic resin.

【発明の詳細な説明】 産業上の利用分野 本発明は密閉形鉛蓄電池に関するもので、特にその電池
容器の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a sealed lead-acid battery, and more particularly to improvements in the battery container.

従来の技術 密閉形鉛蓄電池はガラス細繊維不織布（リテーナと称す

そう外部にもれず、携帯に便利ケ小型電源として広く普
及している。Conventional technology Sealed lead-acid batteries are made of fine glass fiber non-woven fabric (called a retainer) and electrode plates that hold the electrolyte and do not flow, so the electrolyte does not leak outside when charging, making it convenient to carry and widely used as a small power source. are doing.

密閉形鉛蓄電池は過充電時に陽極板で発生した酸素ガス
６を陰極板に吸収させて陰極板からの水素ガスの発生を
防止している。In a sealed lead-acid battery, the cathode plate absorbs oxygen gas 6 generated at the anode plate during overcharging, thereby preventing hydrogen gas from being generated from the cathode plate.

が挙げられている。However, if the charging current exceeds a level that causes a drop, the amount of oxygen gas generated by the anode plate will be greater than the oxygen gas absorption capacity of the cathode plate, and hydrogen gas will also be generated from the cathode plate, so if the battery is completely sealed, becomes quite high pressure. Therefore, a safety valve is provided that opens when the internal pressure of the battery increases. Generally, this type of safety valve has a structure in which a rubber valve is placed over a valve barrel. However, with such a rubber valve structure,
Mechanizing the fitting of a rubber valve into a valve barrel is difficult and requires a lot of assembly time, so mechanization is facilitated by integrally molding a safety valve with a battery case using the battery capacity of a film-like or sheet-like synthetic resin body. It was proposed that the structure be suitable for mass production. Polyethylene and polypropylene resins are mentioned as materials for these film-like or sheet-like synthetic resin bodies.
