Abstract

PURPOSE:To mininize the deformation of a container when using a thin-film plastic bag as a storage container of a generating element by storing the generating element in a film plastic bag, arranging reinforcing plates on both sides of the single bag or multiple stacked bags, and fixing them with bands or thermal- contraction tubes, etc. CONSTITUTION:Electrode plate group is constituted with two negative electrode plates 1, and a positive electrode plate 2, and mat-like separators 3 mainly made of glass fibers inserted between them. They have a positive electrode terminal 4, a negative electrode terminal 5, and resin rings 6, 7. The electrde plate group thus obtained is stored in a multi-film bag container 8 made of polyethylene resin and polyester resin to constitute a unit cell 10. Then, a vent hole 9 is provided. Next, three unit cells 10 are stacked in serial connection, plastic plates 11 reinforced with glass fibers are put on both sides, and further these plastic plates 11 are firmly fastened from outside with thermal-contraction tubes 12. Next, dilute sulfuric acid is injected into each unit cell by restricting it to a quantity not flowing freely in the cell or less.

当な方法で固縛する構成は既に提案されている。Conventional Structure and Problems One type of sealed lead-acid battery with negative electrode absorption is one in which negative electrode plates and positive electrode plates are alternately stacked with a mat-like separator mainly made of glass fiber interposed therebetween.
-The battery is assembled into a highly rigid and hard-to-deform battery case while maintaining the front and rear group pressure, and after injecting dilute sulfuric acid as an electrolyte to the amount that flows inside the battery, the pressure inside the battery is reduced. There is a configuration in which the storage battery is sealed by a check valve that becomes open only when the value exceeds a certain value and releases the gas inside the storage battery to the outside of the storage battery. In this case, it is important to always maintain the electrode plate group as a power generation element in a pressurized state above a certain pressure in the storage battery in order to maintain good charge/discharge characteristics. This is because it is essential to maintain good adhesion between the electrode plates and the separator inside the storage battery. Note that a configuration has already been proposed in which reinforcing plates are applied to both outer sides of a group of electrode plates serving as a power generating element, and the reinforcing plates are secured using a heat shrink tube or other suitable method.
