2PbSOn + 21-12 0 The thicker the sulfuric acid aqueous solution, the higher the specific gravity, so the electrolyte with high specific gravity generated during charging falls to the bottom within the cell, creating a stratification in which the upper part has a lower specific gravity and the lower part has a higher specific gravity. . This stratification is
This is undesirable because it causes damage to the electrode and the lower electrode plate deteriorates.

なる問題があった。In order to solve this problem, it is necessary to carry out severe overcharging of 20 to 30% of the discharge voltage and stir the electrolytic solution by a large amount of gassing from the electrode plates. There was a problem in which this overcharging was repeated (and the water was electrolyzed and decreased, requiring frequent replenishment, as well as accelerating corrosion of the positive electrode grid, which could be fatal to the JJO).

Question with one electrode,
Alternatively, the voltage can be applied between two separately provided electrodes.
This is an attempt to efficiently eliminate the stratification of lead-acid batteries for charging and discharging that have a fluid electrolyte due to overcharging of raw nails.

Furthermore, since gas can be generated only after the terminal voltage reaches a specified value or F, that is, when the charging of the battery has progressed to a certain extent, the loss of charging power is also reduced.
