Method of manufacturing lead or lead alloy plate lattice for lead-acid battery and lead-acid battery

摘要

Disclosed are a method of manufacturing a lead (or lead alloy) plate lattice for a lead-acid battery, featured in that a melt of lead or a lead alloy is continuously extruded under temperatures lower by 10 to 100° C. than the melting point of lead or the lead alloy, followed by subjecting the extrudate to cold rolling under temperatures lower by 50 to 230° C. than the melting point of lead or the lead alloy with the total draft rate set at 10 to 90% and subsequently cooling and processing the cold rolled extrudate so as to manufacture a plate lattice, and a lead-acid battery comprising the particular lead (or a lead alloy) plate lattice.
