Description
【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の製造法に関するものである。[Detailed description of the invention] Industrial applications The present invention relates to a method for manufacturing a sealed lead acid battery.

酸素ガスを負極で吸収し、負極においてはその還元に電
気が使われるために、実質的に水素ガスの放出はない。In conventional sealed lead-acid batteries, the electrode plates and the separator are impregnated with electrolyte, so that there is no free liquid, so there is no risk of liquid spillage. Furthermore, during overcharging, oxygen gas generated from the positive electrode is absorbed by the negative electrode, and electricity is used for its reduction at the negative electrode, so that virtually no hydrogen gas is released.

セパレータ、８は陽極板、９，９′は端子である。However, if hydrogen gas is generated from the negative electrode due to a self-discharge reaction during storage, or if oxygen generated from the positive electrode during rapid charging is greater than the absorption of the negative electrode, hydrogen and oxygen gas may be generated inside the battery. Press to enter the pressure increase state. At this time, if a spark is generated inside the battery due to a short circuit, an explosion will occur. In order to avoid this explosion, as shown in FIG. 2, a safety valve is provided above the battery case 1 to prevent the pressure from increasing beyond a predetermined level. This safety valve is constructed by covering a valve cylinder 3 that opens above the battery case lid 2 with a rubber cassette f4, and further pressing a rubber cap 4 with a pressing plate 5. In addition, 6 is a cathode plate, 7 is a separator, 8 is an anode plate, and 9 and 9' are terminals.

除去する作業が必要であった。Problems to be Solved by the Invention In the above-mentioned safety valve, after the electrolytic solution was injected through the valve cylinder 3, the rubber cap 4 was placed over the valve, and the presser plate 5 of the rubber cap was welded. Therefore, it is difficult to position the electrolyte injection nozzle, and gas is generated from the electrode plate during injection, resulting in poor gas-liquid replacement in the valve cylinder 3, making injection difficult. Furthermore, it was necessary to remove droplets before welding the holding plate 5 after injecting the electrolyte.

する。Embodiment An embodiment of the present invention will be described.◇ As shown in Fig. 1, a terminal is held in a polypropylene battery case lid 2 having a safety valve with a rubber cap 4 covering a valve barrel 3 that opens to the side. 9 and the electrode plate group are connected, and a cylindrical seed of 0.1 fl thick consisting of three layers of polypropylene, polyvinylidene chloride, and polyester is formed to surround the electrode plate group and serve as a cover for the battery case lid 20 safety valve. Then, the upper part of the cylindrical sheet is welded to the battery case lid 2, the electrolyte is injected by contacting the liquid injection nozzle with the separator 7 from below the cylindrical sheet, and the lower part is sealed with hot bath bonding. By forming the battery case 1, a 2VI Ah (10H,R,) sealed lead-acid battery is manufactured. In this case, the injection time is 4 seconds without overflowing, but when injecting liquid from the valve cylinder of a conventional sealed lead acid battery, the pressure is reduced for 4 seconds after 2 seconds, and the injection time is 2 seconds. A total of 8 seconds of liquid injection time is required.

。Effects of the Invention As described above, according to the present invention, the injection port for the electrolyte is widened, the injection can be performed quickly, and the injection time can be halved from 8 seconds to 4 seconds. This has the effect of improving workability by eliminating the need for post-processing, and since the battery case also serves as a cover for the safety valve, the conventional rubber cap press plate is no longer necessary, reducing the number of parts by one.
