た。Problems to be Solved by the Invention In sealed lead-acid batteries, attempts have been made to increase the size of the electrode plates in order to increase the battery capacity. However, in the case formation, the amount of electrolyte that can be injected was restricted, and the electrode plate could not be enlarged. Also, if the electrode plate is enlarged, it is disclosed in JP-A-1-294361 that a container for supplying an electrolytic solution is detachably attached to a filling port of a battery case, and the formation is performed while replenishing the electrolytic solution. I have. There is also a method of replenishing the electrolyte during the formation of the battery case. However, there is a problem that all of these methods require man-hours and increase the cost.
本発明は、前記のような従来の問題点を解決し、極板

からずに電槽化成を可能にする新しい化成方法を提供す
るものである。The present invention solves the above-mentioned conventional problems, and provides a new chemical conversion method that enables a battery container to be formed without increasing the number of steps even if the electrode plate is made larger and the capacity is increased. Things.

ける電流値を減少させることを特徴とする。Means for solving the problem, that is, the present invention, in the formation of the electrode plate in the battery case where the amount of electrolyte that can be injected is regulated, the battery voltage rises, a state that is constant with respect to the formation time, In other words, there is provided a method for forming a battery case of a sealed lead-acid battery, characterized in that discharging is performed before reversal of the polarity. More preferably, the present invention is characterized in that the current value in the battery case formation after the reversal is reduced.

が少なくなると考えられることによる。Operation According to such a method, the formation can be performed while reducing the decrease of the electrolytic solution during the formation of the battery case. This is because the so-called Neumann effect for gas disappearance is promoted by lowering the formation current value after the electrode plate is turned, because the formation state of each electrode plate is made uniform by the halfway discharge before inversion, This is because the decrease of the electrolyte is considered to be small.
そしてさらに充電電気量が従来の80％とすることで、
現行と同等の容量を得ることができる。And by further charging 80% of the conventional electricity,
A capacity equivalent to the current capacity can be obtained.
実施例 以下、本発明の実施例について詳細に説明する。Examples Hereinafter, examples of the present invention will be described in detail.
実施例１ 電池には6V,4Ah（20HR）の密閉型鉛蓄電池を用いた。

各極板の充電状態を均一化し、化成効率を向上させるた
めである。Example 1 A sealed lead-acid battery of 6 V, 4 Ah (20 HR) was used as a battery.
The configuration of the electrode plates was such that two anode plates and three cathode plates were used, each having a height of 65 mm and a width of 43 mm. In the chemical conversion method of the present invention, first, an electrode group consisting of an unformed electrode plate is incorporated into a battery case, and a diluted sulfuric acid electrolyte having a specific gravity of 1.225 is injected at 37 cc / cell.
The battery is charged at a constant current of 0.8A, and 12
At the time (before inversion), discharge is performed at 0.8 A for 1 hour. The reason for performing the discharge here is to make the charged state of each electrode plate uniform as early as possible and to improve the formation efficiency.

いては同等以上ということがわかる。FIG. 3 shows the weight reduction and battery capacity of the battery at the time of battery case formation of Example 1 of the present invention, together with the patterns of Conventional Examples a and b having the same liquid injection specification. FIG. 3 shows the first embodiment of the present invention.
It can be seen that the weight loss is smaller than that of the pattern of the conventional example a and the pattern of the conventional example b with the same amount of charged electricity, and the battery capacity is equal to or more than that.
上記のように、極板の転極以前に放電を実施すること
により、電槽化成時の重量減を少なくすることができ、
その分、極板を大きくすることができ、容量アップが可
能となる。しかも、工数がかからずに、電槽化成をする
ことができる。ただし全充電量は放電電気量を差し引い
たものである。As described above, by performing the discharge before the polar plate is inverted, the weight loss at the time of forming the battery container can be reduced,
As a result, the size of the electrode plate can be increased, and the capacity can be increased. In addition, the battery case can be formed without any man-hour. However, the total charge amount is obtained by subtracting the discharge electricity amount.
以下、本発明の第２の実施例について図面を参照しな

（転極以前）において0.8Aで放電を１時間実施する。Hereinafter, a second embodiment of the present invention will be described with reference to the drawings. Using the same electrode group as the electrode group, an electrolyte having a specific gravity of 1.235 was injected at 34 cc / cell, and charged at a constant current of 0.8 A in the pattern shown in FIG. After that (before inversion), discharge is performed at 0.8 A for 1 hour.

である。After discharging, the battery is charged again at 0.8 A for 4 hours, and thereafter, the current value is reduced to 0.2 A, and the battery is charged for 49 hours. The reason why the current value is reduced after the pole plate is inverted is to promote the so-called Neumann effect in which oxygen generated from the anode is absorbed by the cathode.

一であった。FIG. 3 shows the weight reduction and battery capacity of the battery at the time of battery case formation according to the second embodiment of the present invention. From FIG. 3, it can be seen that the weight loss of Example 2 of the present invention is small, but the battery capacity after battery case formation is equal to or greater than that of the conventional example. Also, as a result of measuring the specific gravity and liquid volume of the electrolytic solution by disassembling the battery after forming the battery case,
The pattern 2 of the conventional example and Examples 1 and 2 of the present invention were almost the same.

とから、さらにコストダウンとなる。As described above, by performing the discharge before the pole plate is inverted, and further reducing the current value of the battery case formation after the polarity conversion,
Since the weight loss during battery case formation can be reduced, the size of the polarizing plate can be increased. In other words, an electrode plate having a height higher than that of the conventional electrode plate is used, and the battery case formation time becomes longer, but the man-hour for replenishing the electrolyte solution during the battery case formation can be completely eliminated. Therefore, the battery case can be formed at low cost. In addition, the amount of electricity to be charged can be reduced to about 80% of the conventional level, further reducing costs.

るものである。Effect of the Invention As described above, the present invention provides a closed plate type battery in which a discharge is carried out before the electrode is inverted in a plate formation in a battery case in which the amount of an electrolyte that can be injected is regulated. This is a battery case formation method for lead-acid batteries.In addition, by reducing the current value of the battery case formation after reversing the electrode plates, the formation efficiency during the battery case formation is increased, and the amount of electrolyte reduction is greatly reduced. Can be done. Therefore, even if the electrode plate size is increased and the capacity is increased, man-hours can be formed in the sealed lead-acid battery without man-hours.
