NEGATIVE ELECTRODE FOR LEAD-ACID BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a negative electrode for a lead-acid battery with improved high-rate discharge characteristic of a lead-acid battery used for an electric vehicle or the like. SOLUTION: A lead-alloy porous base substance is filled with active material mix paste obtained by adding 1-5 pts.wt. of conductive carbon and 1-5 pts.wt. of activated carbon to 100 pts.wt. of a negative electrode active material within 2-8 pts.wt. of the total addition quantity of the two kinds of carbon materials, and a chemically-unconverted negative electrode thereby obtained is subjected to a formation treatment.
