産業上の利用分野
本発明は鉛電池の製造法、特に電槽化成方法に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for manufacturing a lead-acid battery, and in particular to a method for forming a battery case.

た。Conventional technology Conventionally, in the case of chemical cell forming, unformed electrode plates were used for both the positive and negative electrode plates, and the electrode plates filled with active material, aged, and dried were assembled as they were, and then placed in an electric cylinder and injected with liquid. I made a battery case.

ガツシングによる正極板での過化成による活物質の泥状
化などの現象を生じていた。Problems to be solved by the invention: When bath chemical formation is performed, the positive electrode plate does not release gas, and when a paste containing a large amount of PBSO, M is used, chemical formation occurs (<, white unformed part due to Pb80°) (Inner rails) exist, which may affect the battery performance or cause the liquid to become cloudy due to peeling after charging and discharging.Also, if an expanded grid is used for the positive and negative electrode plates, it may be difficult to chemically form the battery in the tank chemically. However, chemical formation methods other than container formation, such as a method in which the electrode plate is suspended in a chemical solution, may not be able to be formed properly due to falling off of the active material, peeling, etc., or the positive electrode may be damaged due to the electrode plate being gushed. Phenomena such as the active material becoming muddy due to hyperchemical formation in the plate were occurring.

じやすい。Means to Solve the Problem Generally, it is the positive electrode plate that is difficult to chemically form, so we conduct a battery case chemical process using a completely chemically formed positive electrode plate and an unformed negative electrode plate.
Therefore, the negative electrode plate is easily charged due to the potential of the positive electrode plate. Furthermore, in a sealed battery, the zero element gas from the net value causes a gas absorption reaction in the oxidation part, which further lowers the value and tends to cause a charging reaction.
作用
正極板に化成法極板、負極板に未化成極板を用いて電槽

極）になっているので０２ガスが発生する。一方、口極

一層その傾向は大きい。したがって正極板のこれらのア
ンバランスを通常の極の電位を保って打いて、負極のみ
電位をカンード方向に上げれば均一に化成される。Working When a chemically formed electrode plate is used for the positive electrode plate and an unformed electrode plate is used for the negative electrode plate, the positive electrode plate has a voltage of 1.46V (VS standard hydrogen [
pole), so 02 gas is generated. On the other hand, at the oral plate, a reduction reaction to pbso, →Pb occurs. This reaction occurs at about 10.2 V (VS - standard hydrogen electrode), so the reaction occurs immediately and the chemical formation progresses (Also, when forming a cell in a sealed battery, the potential decreases due to gas absorption, - If the positive and negative electrode plates are not chemically formed, they will not become PbO unless the voltage exceeds 1.4V, so they often remain as PbOx, which is an intermediate between the positive and negative electrode plates. On the other hand, since it is generally thicker, it tends to cause imbalance due to directionality and time delay in the chemical formation process, and it is difficult to form the chemical uniformly.This tendency is even greater in the case of battery tank formation.Therefore, these imbalances of the positive electrode plate If you strike a balance by keeping the normal potential of the pole and raising the potential of only the negative pole in the direction of the cand, it will be uniformly formed.

Then, H adjusted to a predetermined concentration

（第２図）。A battery that uses only unformed electrode plates after forming the battery case (conventional product)
In this case, PBSO and a film remained on the surface of the positive electrode plate, resulting in poor chemical formation. On the other hand, in the battery whose positive electrode plate was immersed in the ammonium persulfate solution (ammonium persulfate product), there was no Pb5O film on the surface, but a small amount remained inside. However, in the battery of the present invention (product of the present invention), almost no PBSO remained, and negative electrode plate formation could be performed without any problem (Fig. 1). In addition, the product of the present invention had the best capacity in proportion to PBSO and H (Figure 2).

It has great industrial value as it is easy to manufacture.
