問題である。Conventional technology and its problems Conventionally, so-called lead powder containing lead oxide as a main component has been used as a raw material in the production of paste-type lead-acid battery plates, and this is kneaded with dilute sulfuric acid to form a paste-like material. It is manufactured through filling and aging processes after filling the body. In this method, there are major problems that it takes a long time in the ripening and chemical conversion steps and that the environment is deteriorated due to acid fog generated in the chemical conversion step.

Since the binding force between the PbO 2 particles is weak, there is a problem that the active material falls off from the electrode plate during use of the battery and the capacity is quickly reduced. For this reason, even in the above document, Teflon particles are added as a binder. However, since a polymer material such as Teflon does not have electric conductivity, it inhibits electron conduction between active materials and causes an increase in internal resistance of a battery.

By forming a lower-grade lead oxide and forming a lower-grade lead oxide than PbO 2 , bonding between the crystals of PbO 2 as the main component is achieved. That is, the powder 1% to 15% is mainly composed of PbO 2 is a lower lead oxide than PbO 2 to prepare an electrode by filling the base body, is electrolyte to the separator, the electrode group consisting of the cathode When dilute sulfuric acid is injected, lead sulfate is generated by a reaction between sulfuric acid and lead oxide lower than PbO 2 . Here, when electricity is supplied by an amount that oxidizes the generated lead sulfate to PbO 2, it is generated by dissolution and precipitation of lead sulfate.
PbO 2 serves to bind between already existing 85-99% of PbO 2 crystals. When a powder containing PbO 2 as a main component is filled in a substrate, the same effect as described above can be obtained by kneading the powder with an aqueous sulfuric acid solution. That is, by kneading a powder containing PbO 2 as a main component with an aqueous solution of sulfuric acid, the surface of the crystal of PbO 2 becomes lead sulfate. Therefore, the PbO 2 crystal can be bonded by returning the lead sulfate to PbO 2 again.
