Abstract

PURPOSE:To remove plate adherence, which is a trouble in the process, without causing the generation of bad influence to performance of a battery, by using dilute sulfuric acid dissolved with sodium salt of a condensation product of beta-naphthalene sulfonic acid formalin as forming liquid. CONSTITUTION:In the so-called block forming in which several sheets of unformed positive and negative plates are alternately arranged to perform forming, dilute sulfuric acid of 1.060 specific gravity dissolved with 1% sodium salt of a condensation product of beta-naphthalene sulfonic acid formalin is used to form an unformed plate for a lead storage battery. Then in this case, a counted result of adhering frequency of the plate has been shown in a table with a result from the vonvertional method. Further from a measured result of potential change of the negative plate and quantity change of residual lead sulfate at the time of forming, the smaller is a reduction speed of lead sulfate, that is, the lower is forming efficiency, a rise-up of potental seems the slower and adherence of the plate seems to be generated the more easily.

Description

【発明の詳細な説明】 本発明は鉛蓄電池用極板の化成方法に関する。[Detailed description of the invention] The present invention relates to a method for forming electrode plates for lead-acid batteries.

うという欠点かあった。Conventionally, in so-called block formation, in which several unformed anode plates and unformed cathode plates are placed alternately and formed, the cathode plate, especially a paste-type cathode plate using lead powder manufactured by the Burton-Pot method, is used. However, there was a drawback in that the cathode plates of the same block adhered to each other near the outer periphery of the electrode plates, so-called lattice ribs, at the final stage of formation.

本発明は、上記の欠点を解消するもので、化成液として

。The present invention solves the above-mentioned drawbacks and is characterized by using dilute sulfuric acid in which a sodium salt of a β-naphthalene sulfonic acid polymerine condensate is dissolved as a chemical conversion liquid.

本発明の一実施例を説明する。An embodiment of the present invention will be described.

数した。Specific gravity 1. The frequency of adhesion of electrode plates when unformed electrode plates for lead-acid batteries were chemically formed using of+o dilute sulfuric acid was counted.

その結果を従来法での結果とともに第１表に示す。The results are shown in Table 1 together with the results of the conventional method.

、極板の付着が発生し易いようである。In addition, although the cause is not very clear, as a result of measuring the potential change of the cathode plate during chemical formation and the change in the amount of residual lead sulfate, as shown in Figure 1, the smaller the reduction rate of lead sulfate, the higher the chemical formation efficiency. It seems that the lower the value, the slower the rise of the potential -F, and the more likely it is that the electrode plates will stick together.

なお、本発明による陰極板は水洗乾燥を経て鉛蓄電池に
組立てらねるため、デモールの鉛蓄電池への混入は僅か
であり、電池性能にはほとんど影響しない。Incidentally, since the cathode plate according to the present invention is assembled into a lead-acid battery after washing and drying, the amount of demole mixed into the lead-acid battery is small and has almost no effect on battery performance.

上述のように、本発明によれば、電池性能に悪影響を与

がある。As described above, according to the present invention, electrode plate adhesion, which is a process trouble, can be removed without adversely affecting battery performance, and
The improved chemical conversion efficiency has the effect of reducing the amount of electricity required for chemical conversion.
