POSITIVE ELECTRODE PLATE FOR LEAD-ACID BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a positive electrode plate for a lead-acid battery which improves a cycle characteristic and a discharge characteristic thereof. SOLUTION: A positive electrode plate for a lead-acid battery whose lattice body is charged with a paste which is prepared by kneading lead powder, (a) whose main component is a minium and lead powder (b) whose main component is a lead monoxide in a kneading liquid whose main component is a sulfuric acid. The lead powder (b) contains a metal lead 15-30 wt.%, and the average diameter set to 4-25μm, and a diameter of 10% that is not more than 2μm put through a sieve.
