Abstract

PURPOSE:To make it unnecessary to use a metal mould for forming the battery jar and improve the sealing reliability of the terminal leading-out portion, by using a bag body of a synthetic resin film or sheet for the battery jar and cap-welding around the opening of the bag body. CONSTITUTION:The bag body 8 is made by attaching two sheets of synthetic resin films or sheets, and the three sides are heat-deposited to make into a cylindrical form. An electrode plate group 6 is installed in the bag body 8 and inserted until the step ]2 of a cap 1 reaches to the opening of the bag body 8. After positioning in such a way, the periphery is welded and sealed perfectly by the supersonic waves or the like. Therefore, the deposited surface of the bag body 8 is preferable to have the same material as the forming cap 1, polypropylene, high density poly-ethylene, or the like being used for this purpose. Furthermore, for the film or the sheet composing the bag body 8, at least one layer of vinylidenechloride is used for the inner layer to prevent the permeation of water from the inside of the battery and the invasion of oxygen from the outside.

要とし、生産に柔軟に対応することか困難であった。Conventional technology A conventional sealed lead-acid battery had a structure in which a group of electrode plates, consisting of a positive electrode plate, a negative electrode plate, and a separator, was inserted into a battery case made of ABS resin, etc., and the lid was glued and sealed. . Due to this structure, if the capacity changes, different containers, lids, etc. are required for each model, which not only increases costs such as the cost of molding molds, but also requires a long time to prepare. Therefore, it was difficult to respond flexibly to production.

ある。Means for Solving the Problems The present invention solves the above problems by using a bag made of a synthetic resin film or sheet as a battery case instead of a hard molded battery case such as ABS. . The ears of the electrode plate group are connected to the terminals of the synthetic resin cap, which is integrally molded with the anode and cathode terminals and the safety valve installed and the exhaust section, and the opening of the bag housing the electrode plate group is inserted. A cap is welded around the bag to ensure airtightness between the bag and the cap.

溶接部を示している。The ears 7.7' of the electrode plate group 6 are welded and joined to the terminals 2.2' protruding downward from the cap 1. The bag body 8 that houses the electrode plate group 6 is made by combining two synthetic resin films or sheets and thermally welding the three sides to form a °C envelope shape. 9 indicates a welded portion.

望ましく。The above-described electrode plate group 6 is stored in a bag 8, inserted until the opening of the bag 8 reaches the stepped portion 12 of the cap 1, and after positioning, the periphery is welded using ultrasonic waves or the like to completely seal. Therefore, it is desirable that the welding surface of the bag body 8 be made of the same material as the molded cap l.
