POSITIVE ELECTRODE PLATE FOR LEAD STORAGE BATTERY AND LEAD STORAGE BATTERY USING SAME

摘要

A lead storage battery is provided in which initial capacity can be increased without decreasing battery life. A positive electrode active material paste is obtained by mixing a raw material containing lead powder that contains metallic lead with lead monoxide as the primary component and the positive electrode plate for a lead storage battery is configured by filling the aforementioned positive electrode active material paste into a lead alloy lattice substrate made. The lead powder is adjusted to have a median diameter of 0.5 10 µm. The metallic lead is adjusted such that when observed with a metallurgical microscope the average particle diameter of the ten highest diameter metallic lead particles (the average particle diameter T10 of the metallic lead) is 10 35 µm.
