(Prior art) Conventional Pb gold alloy containing no Sb is Pb-Ca-8n.
The surface of the alloy grid substrate is filled with a paste consisting of lead oxide and dilute sulfuric acid as an active material to form an anode plate, and the active material is filled with a paste of lead dioxide to which dilute sulfuric acid and barium sulfate are added to form a cathode plate. A mat-like cell made of glass fibers with a fiber diameter of 20μ or less is formed between the two electrode plates.
A sealed lead-acid battery was obtained by laminating the batteries with 1,320 ml of dilute sulfuric acid (ratio, 7) (1,320) added to dilute sulfuric acid as an electrolytic solution. It is something that exists.

The reason why Na2SO4 is added to dilute sulfuric acid in the above electrolyte is that if a storage battery is discharged and then left as is for about a week and then is to be charged again, the charge acceptance characteristics can be improved and the battery can be charged immediately. This is because it can be done.

Note that if only dilute sulfuric acid is used as the electrolyte, the charge acceptance characteristics described above are poor and charging cannot be performed immediately. However, since the life characteristics of the storage battery are almost the same as when only dilute sulfuric acid is used as the electrolyte, there has been a desire to improve this.

The reason why the lead alloy that forms the lead alloy substrate is not specifically made to contain Sb is that if the lead alloy is contaminated with Sb, even if At2 (S04) is added to dilute sulfuric acid in the electrolytic solution.
Even if a mixture of s, H, pd4 or Mg(SO4) and H3PO4 is used, the above-mentioned charge acceptance characteristics cannot be improved, and charging cannot be performed even if the discharge level is left unattended. It was something that didn't exist.
