記Pb又はPbOをPb又はPbO2の活物質にするもの
であるが、この場合Pbに比しPbO2にするのに多
量の電気量を必要とするものであつた。特に密閉
型蓄電池においてはこの電気量のアンバランスが
大きくなると化成処理工程に著しい影響を及ぼす
ものであつた。即ち、陽極板と陰極板とを電槽内
に組込んだ状態にて化成を行う場合、陽極板は
200％近くの電気量を必要とするのに対し陰極板

分解を生じて電解液を損失する。この対策として
電解液を補充すればよいが、多数の電池において
これを常時観察することは極めて煩雑な手数を要
するものであつた。 Conventionally, a lead or lead alloy substrate is filled with a paste made by pouring dilute sulfuric acid and water into a PbO active material raw material and kneading it, and then undergoing an aging process to form a filling plate and chemically converting the above Pb or PbO into Pb or PbO. However, in this case, compared to Pb, it required a large amount of electricity to convert it into PbO 2 . Particularly in the case of sealed storage batteries, if the imbalance in the amount of electricity becomes large, it has a significant effect on the chemical conversion treatment process. In other words, when performing chemical conversion with the anode plate and cathode plate assembled in the battery case, the anode plate
While nearly 200% of the amount of electricity is required, the cathode plate completes the formation with about 120 to 130% of the amount of electricity. Therefore, if the cathode plate is anodized at the same time as the anode plate, the cathode will overcharge, generate H 2 gas, and cause water decomposition, resulting in loss of electrolyte. As a countermeasure to this problem, it is possible to replenish the electrolyte, but it is extremely troublesome to constantly observe this in a large number of batteries.

電池を組立てた後注液を行つて密閉化していた
が、この方式による場合には作業が煩雑となりか
つ電池のコストが著しく高くなる等の欠点があつ
た。 Therefore, in the past, the anode plate and the cathode plate were chemically formed separately, the battery was assembled via a retainer mat, and then the liquid was injected and sealed, but this method required complicated work. However, there were disadvantages such as a significant increase in the cost of the battery.
従つて、化成工程において、陽極板化成の電気
量を少くすることによつてガスとして逸散する電
解液量を防ぎしかも化成効率を向上せしめうる密
閉型鉛蓄電池の製造法の出現が要望されているも
のであつた。 Therefore, there is a need for a manufacturing method for a sealed lead-acid battery that can prevent the amount of electrolyte dissipated as gas by reducing the amount of electricity required for anode plate formation in the chemical formation process, and improve the chemical formation efficiency. It was something that existed.

電池の製造法である。 The present invention was developed as a result of intensive research in response to such demands. That is, the present invention uses lead (Pb) and an unformed anode plate in which a lead or lead alloy substrate is filled with an active material raw material whose main component is trilead tetroxide (Pb 3 O 4 ).
Alternatively, a group of electrode plates in which an unformed cathode plate filled with an active material whose main component is lead oxide (PbO) and an unformed cathode plate are stacked together via a retainer mat is stored in a battery case, and each electrode plate is stacked in the battery case. This is a manufacturing method for sealed lead-acid batteries characterized by chemical formation.

つて電槽内にて未化成の陰極板と同時に化成する
ことが出来るのである。 The present invention uses Pb 3 as an active material raw material for an unformed anode plate.
By using a paste whose main component is O 4 , this Pb 3 O 4 reacts with sulfuric acid during the chemical conversion process to easily generate β-PbO 2 , which reduces the amount of electricity needed to perform chemical conversion. This makes it possible to chemically form the unformed cathode plate at the same time in the battery case.
次に本発明の実施例について説明する。 Next, examples of the present invention will be described.
実施例
Pb3O4１Kgに注水76cc、希硫酸（比重1.265）
150ccを夫々加えてペースト状に練合させたもの
を鉛合金基板に充填して未化成陽極板とする。Example: Pour 76cc of water into 1Kg of Pb 3 O 4 , dilute sulfuric acid (specific gravity 1.265)
150 cc of each was added and kneaded into a paste, which was then filled into a lead alloy substrate to form an unformed anode plate.

する。 On the other hand, cathode plates are conventionally made by adding 40 cc of water and 80 cc of dilute sulfuric acid (specific gravity 1.265) to 1 kg of active material raw material mainly composed of Pb or PbO, kneading it into a paste, and filling it onto the lead alloy substrate surface. Use a chemically formed cathode plate.

（ｔ＝14mm）を介して電槽内に収納して蓄電池を
組立て、これに比重1.240の希硫酸をセル当り350
〜360cc注液して化成して密閉型鉛蓄電池をえた。 After the bipolar plates are aged and dried, they are stored in a battery case via a retainer mat (t = 14 mm) to assemble a storage battery, and then diluted sulfuric acid with a specific gravity of 1.240 is added at 350 ml per cell.
A sealed lead-acid battery was obtained by injecting ~360cc of liquid and chemically converting it.

た。 As is clear from FIG. 1, with the anode plate in the lead-acid battery manufacturing method of the present invention, sufficient chemical formation can be carried out with less than 130% of the amount of electricity equivalent to that of the cathode plate, so overcharging of the cathode plate is avoided. A sealed lead-acid battery which prevents electrolyte from escaping and has good gas absorption properties without being compressed was obtained.
これに対し従来の方法による密閉型鉛蓄電池の
未化成陽極板による場合には電解液の分解量が多
くガスを多量に発生し密閉することが出来ないも
のであつた。 On the other hand, in the case of using an unformed anode plate for a sealed lead-acid battery according to the conventional method, the amount of electrolyte decomposed is large, and a large amount of gas is generated, making it impossible to seal the battery.

有する。 As detailed above, according to the method of manufacturing a sealed lead-acid battery of the present invention, the amount of electricity used to form an unformed anode plate is significantly reduced, and the formation can be performed using approximately the same amount of electricity as that for an unformed cathode plate. It has remarkable effects such as making it possible to carry out chemical formation at the same time in the battery container, preventing the electrolyte from escaping, and improving the chemical formation efficiency.
