Abstract

PURPOSE:To suppress formation of an irreversible PbSO4 layer and improve the standing performance after overdischarge by constructing a positive plate with more than one positive active mass layers having different filling densities. CONSTITUTION:A positive plate 10 is constructed with more than one positive active mass layers 11 and 12 having different filling densities, and the filling density of the active layer 11 located in the vicinity of a current collector makes higher than that of the active mass layer 12. Pore volumes and pore diameters in the vicinity of the current collector 13 are reduced. As a result, fine pores are blocked and penetration of electrolyte is suppressed, and diffusion of electrolyte to the vicinity of the current collector is suppressed. When the diffusion of electrolyte to the vicinity of the current collector is prevented, the formation of PbSO4 layer (this layer becomes inactive while a battery is allowing to stand, that is, irreversible PbSO4 is formed) caused by reaction of PbO2 layer on the surface of the current collector with SO4<--> ion in the electrolyte is suppressed. Therefore, the standing performance after overdischarge is improved.

（司　背景技術 一般に鉛蓄電池にお°いては、過充電による集電体の腐
蝕を防止Ｔるために、定電圧充電法が採用されている。(Tsukasa) Background Art Generally, in lead-acid batteries, a constant voltage charging method is adopted in order to prevent corrosion of the current collector due to overcharging.

増大することになり。In the anode plate, if the anode plate is left with a load connected after overdischarging, a thin layer of PbSO4 (lead sulfate), which becomes a high resistance material, is generated between the current collector and the active material interface. In particular, in the electrolyte limited type, the PbS
As the O4 layer is formed, the concentration of the electrolyte also decreases, leading to an increase in internal resistance.

に至っていないのか実情である。There are methods of adding phosphoric acid, sodium sulfate, or magnesium sulfate to the electrolytic solution, or adding cadmium, lithium, or titanium to the lead-calcium alloy that is the current collector composition, but their effects are unsatisfactory. The reality is that this has not yet been achieved.

図（ａ）〜（ｄ）の経違によるものと考えられる。Now, the formation mechanism of irreversible pbso4 that forms at the interface between the anode active material layer and the current collector after overdischarging is as follows.
This is thought to be due to the meridian in Figures (a) to (d).

The PbO2 layer (3) is formed by changing to PbO2 (FIG. 1(b)).
