Ｏ４ となり、集電能力が低下する問題点がある。[Problems to be Solved by the Invention] As described above, in the conventional manufacturing method of electrode plates for lead-acid batteries, the moisture in the paste is gradually removed during the aging process after filling the paste. In this case, separation of the current collector and the unformed active material may occur. When overcharging is performed in a battery using such a peeled electrode plate, the gas emitted from the current collector moves the active material, making it easier for the active material to peel off from the current collector. There is a point. In addition, since the current collector in the peeled part comes into contact with dilute sulfuric acid, which is an electrolytic solution, it reacts with PbS.
There is a problem in that the current collecting ability decreases due to O4.
