産業上の利用分野
本発明は、鉛蓄電池用極板の製造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 electrode plates for lead-acid batteries.
従来の技術
鉛蓄電池用極板の活物質の気孔率は５０〜６０憾である
。一般に、活物質の気孔率を増加することにより、活物
質の利用率は向上し、特に低温での高率放電性能が向上
する。そのため、ペースト練合の時、水分量および硫酸
量を調節して気孔率を設定し放電性能を管理している。The porosity of the active material of the conventional electrode plate for lead-acid batteries is 50-60. In general, increasing the porosity of the active material improves the utilization rate of the active material, and particularly improves the high rate discharge performance at low temperatures. Therefore, when mixing the paste, the amount of water and sulfuric acid are adjusted to set the porosity and manage the discharge performance.

れる。Problems to be Solved by the Invention The electrode plate is manufactured by filling a grid with paste and then undergoing aging and chemical conversion processes. The porosity of the active material of the chemically formed electrode plate is influenced by the aging and chemical formation process, or depends on the properties of the paste. Forms pores. Fine pores are formed by the growth of crystals of lead sulfate (including basic lead sulfate), and relatively large pores are thick due to the influence of water (the porosity changes depending on the amount of sulfuric acid and water content). It is determined.

への充填も困難になるという欠点を有している。Although it is possible to improve charge and discharge performance by increasing the porosity, there are limits. If the amount of water and the amount of lead sulfate are too large, the paste becomes soft during paste kneading, which not only makes paste production unstable, but also makes it difficult to fill the grid.
問題点を解決するための手段
本発明は、上記の如き欠点を除去するもので、熟成前に
ペーストを充填した極板を０″Ｃ以下に冷却し水・分を
凍結させ、次いで解氷後熟酸を行うものである。Means for Solving the Problems The present invention eliminates the above-mentioned drawbacks.Before ripening, the electrode plate filled with paste is cooled to below 0''C to freeze the water, and then after thawing. It is used to perform ripe acidification.
作用
これにより、極板の活物質の気孔率を増加させ、充放電
性能を向上することができる。As a result, the porosity of the active material of the electrode plate can be increased, and the charging and discharging performance can be improved.
実施例 本発明の一実施例を説明する。Example An embodiment of the present invention will be described.

度から１０４程度増加することができる。Water and dilute sulfuric acid with a specific gravity of 1.260 are added to lead powder and kneaded to produce a paste, which is then filled into a grid. Thereafter, this electrode plate is cooled to below 0''C to freeze the moisture contained within the electrode plate, and then the ice is thawed and ripened.A suitable aging temperature is about 50''C. As a result, the porosity can be increased from about 50 to 6 (l) to about 104.

A JIS cycle test was conducted. The results are as shown in FIG. 1, and it can be seen that the product of the present invention has a longer initial duration and an increased porosity than the conventional product. Furthermore, the charge/discharge cycle life was almost the same.

Furthermore, when the water content during kneading was increased in order to ensure the same initial capacity as the product of the present invention in this test, the paste became soft (which caused frequent troubles during paste filling).
