るのである。To explain the discharge reaction behavior of this type of battery, at the initial stage of discharge, the concentration of the electrolyte on the surface of the electrode plate is the same as the concentration of the electrolyte impregnated and retained in the separator that is brought into close contact with the electrode plate, but the discharge starts. Then, the reaction proceeds from the electrode plate surface, and the electrolytic solution concentration on the rounded electrode plate surface decreases, creating a concentration gradient, and the electrolytic solution impregnated and held in the separator is diffused to the electrode plate surface. In other words, the amount of electrolyte consumed by the electrode plates is replenished by diffusion from the separator.

! In addition, since the pore diameter of the PbSO4 active material layer is smaller than that of a Pb active material layer, the electrolyte cannot be smoothly supplied to the deep part of the electrode plate, resulting in the inconvenience that a capacity commensurate with the amount of electrolyte cannot be obtained. there were.
