問題である。Conventional technology Conventionally, so-called lead powder containing lead oxide as the main component has been used as a raw material in the production of paste-type lead battery electrode plates, which is kneaded with dilute sulfuric acid to form a paste, which is then filled into a grid. It is manufactured through aging and chemical conversion processes. The major problems with this method are the long time required for the ripening and one-heating steps, and the environmental deterioration caused by the acid mist generated during the chemical conversion step.

、活物質問の電子電導を阻害し、電池の内部抵抗を増加
させる原因となる。Problems to be Solved by the Invention However, the anode made by this method does not contain P as the active material.
Since the binding force between the bo□ particles or the adhesion to the substrate is weak, there is a problem that the active material falls off the electrode plate during use of the battery, resulting in an early decrease in capacity. For this reason, Teflon particles are added as a binder in the above-mentioned literature as well. However, since polymeric materials such as Teflon do not have electrical conductivity, they inhibit the electronic conduction of living materials and cause an increase in the internal resistance of the battery.

造方法を提供するものである。The present invention solves the problems mentioned above in an anode plate obtained by integrally molding a backstopping powder mainly composed of Pbo with a substrate, which has excellent binding strength for living matter and has low resistance. The present invention provides a method for manufacturing a low electrode plate.
課題を解決するための手段
上記課題を解決するため、本発明では以下のような手段

（１） ＰｂＯ□を主成分とする粉末がＰｂあるいは
Ｐｂ量か１０％以上である鉛酸化物を含むこととした。(1) The powder whose main component is PbO□ contains Pb or a lead oxide having an amount of Pb of 10% or more.

のである。Effect of the present invention The present invention includes Pb or lead oxide having a Pb content of 10% or more in a powder mainly composed of PbO□, and by adding an alkaline aqueous solution such as a sodium hydroxide aqueous solution to this and kneading it. This is based on the following effects.

インダーとなる。(1) During kneading, PbO□ and Pb or Pb in the lead oxide that has come out from the surface after the oxide layer was destroyed by the kneading come into contact. At this time, the alkaline aqueous solution added for kneading becomes an electrolyte and an electrochemical reaction occurs. That is, PbO□ is reduced and Pb is oxidized to form Pb (
OH)z or this is dissolved in an alkaline aqueous solution and becomes 1
(PbOz is produced. When dilute sulfuric acid, which is the electrolyte of a lead battery, is injected, these substances quickly react with it and become lead sulfate. This lead sulfate is electrolytically oxidized into Pbo
, the returned PbO□ becomes a binder that binds between crystals of PbO□, which is already present in large amounts as the main component.

腐食され両者の密着性が向上する。(2) The paste prepared according to the present invention is strongly alkaline because an alkaline aqueous solution is used as the kneading liquid. Therefore, when this paste-like material is filled into a base made of lead or a lead alloy, the surface of the base is strongly corroded and the adhesion between the two is improved.
