本発明は、電解液中での極板群圧力の測定装置
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for measuring electrode group pressure in an electrolytic solution.
従来、鉛蓄電池を組み立てる際には、極板群に
適当な圧力、所謂群圧力を加えて電池を組み立
て、電池寿命の向上を図つている。従つて、鉛蓄
電池を組み立てる際には、所定寸法の電槽に収納

板群が組み立てられている。そして、極板群圧力
を示す尺度としては、極板群を電槽に挿入する際
の荷重、所謂、挿入荷重が便宜的に用いられてい
た。 Conventionally, when assembling a lead-acid battery, an appropriate pressure, so-called group pressure, is applied to the electrode plate group to assemble the battery, in order to improve the battery life. Therefore, when assembling a lead-acid battery, an electrode plate group is assembled using an anode plate, a cathode plate, a separator plate, and a glass mat having a thickness such that a predetermined group pressure is applied when stored in a battery case of a predetermined size. There is. As a measure of the pressure of the electrode plate group, the load when inserting the electrode plate group into the battery case, the so-called insertion load, has been conveniently used.

群圧力を決めるに当つて、予め、挿入荷重−極板
群圧力の検量線を求めなければならないという複
雑な操作が必要であつた。 However, the above-mentioned insertion load varies depending on the electrode group configuration, the material of the battery case, or the presence or absence of a spacer body for adjusting the electrode group pressure. Determining the group pressure from the load requires a complicated operation in which a calibration curve of insertion load versus electrode group pressure must be determined in advance.

は、セパレータやガラスマツトに通常“へたり”
と呼ばれている現象が発生するので、たとえ挿入
荷重の測定から群圧力を求めても電解液が入つた
状態での極板群圧力は全く不明であるという問題
があつた。 In addition, the calibration curve of insertion load vs. electrode group pressure was obtained when the electrode plates, separators, glass mats, etc. were in a dry state.
Because of this phenomenon, there was a problem in that even if the group pressure was determined from the measurement of the insertion load, the group pressure of the electrode plates with the electrolyte in them was completely unknown.
本発明は、以上のような問題点を解決するた
め、電解液の入つた状態での極板群圧力を測定す

板群圧力を求められるようにしたものである。 In order to solve the above-mentioned problems, the present invention makes it possible to measure the pressure of the electrode group in a state where an electrolyte is contained, and to determine the optimal electrode group pressure in a lead-acid battery. This is what I did.
本発明は以上のような問題を解決するため、第
１図以下に示したような装置によつて初めて電解
液中での極板群圧力の測定が可能となつた。 In order to solve the above-mentioned problems, the present invention has made it possible for the first time to measure the electrode group pressure in an electrolytic solution using a device as shown in FIG. 1 and subsequent figures.

ージ７によつて検出する。 That is, to explain with reference to FIG. 1, a rib 3 similar to the partition wall of the battery case is attached to the inner wall of a fixed wall 2 fixed on a measuring table 1, and a movable wall 4 is provided opposite the fixed wall 2. The movable wall 4 is also provided with ribs 3 on its inner wall surface. Pressure is applied between the fixed wall 2 and the movable wall 4 by sandwiching a group of electrode plates 6 housed in an electrolyte-resistant bag 5 such as a plastic bag, but the presence of the ribs 3 makes it difficult to apply pressure. is the same as inside the battery. The outer wall surface 9 of the movable wall 4 is attached to a slide table 10 via a steel plate 8 to which a strain gauge 7 is adhered. The slide table 10 moves forward and backward by operating the rotary handle 11, and the movable wall 4
When the electrode plate group 6 is brought into pressure contact with the electrode plate group 6, the pressure contact force is detected by the strain gauge 7.
次に、極板群圧力の測定方法を具体的に説明す

20Kg／ｄm2に設定後はハンドル１１を固定し、そ
の後の歪量の変化を圧力に換算したものを第２図

板群圧力は曲線ａのように徐々に低下し、約１時
間後には17Kg／ｄm2程度になる。この時点で、60
℃に加温した比重1.260の希硫酸800mlをビニール
袋５に注入した。 First, assemble an unformed N50Z battery plate group consisting of 5 anode plates, 6 cathode plates, and a separator 10, store the plate group 6 in an appropriately sized plastic bag 5, and place it between the fixed wall 2 and the movable wall. I placed it between 4.
Thereafter, the movable wall 4 was pressed against the electrode plate group 6 by turning the handle 11, and a pressure of 20 kg/dm 2 was applied.
After setting the pressure to 20 kg/dm 2 , the handle 11 was fixed, and the subsequent change in strain amount was converted into pressure as shown in FIG. As can be seen from FIG. 2, even in a dry state, the electrode group pressure gradually decreases as shown by curve a, and reaches about 17 kg/dm 2 after about 1 hour. At this point, 60
800 ml of dilute sulfuric acid with a specific gravity of 1.260 heated to ℃ was poured into the plastic bag 5.
その結果、セパレータ、マツトのへたりが発生

影響しているためである。 As a result, the separators and mats became sagging, and the electrode group pressure suddenly decreased as shown by curve b.
This phenomenon was caused by the heat of reaction between the dilute sulfuric acid and the unformed electrode plates, which caused the separator and the mat to undergo significant settling. This means that instead of a plate, a thickness of 3
A similar experiment was conducted using a vinyl chloride plate with a diameter of 1.5 mm, and the temperature of the injected dilute sulfuric acid was changed. This is clear from the sudden increase in the amount of Furthermore, Figure 3 shows the electrode group pressure.
After setting it to 20Kg/dm 2 , leave it for 1 hour and then inject dilute sulfuric acid 1.
This is the value after hours. When the temperature of injected dilute sulfuric acid is below 30°C, the value is 10 Kg/dm 2 regardless of the temperature, because in this range, only the settling due to wetting is affected.

The industrial value of the present invention is extremely great in that it is an effective means for confirming its properties in the future.
