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 (orlead alloy) plate lattice for a lead-acid battery,featured in that a melt of lead or a lead alloy iscontinuously extruded under temperatures lower by 10 to100°C than the melting point of lead or the lead alloy,followed by subjecting the extrudate to cold rollingunder temperatures lower by 50 to 230°C than the meltingpoint of lead or the lead alloy with the total draftrate set at 10 to 90% and subsequently cooling andprocess.ing the cold rolled extrudate so as tomanufacture a plate lattice, and a lead-acid batterycomprising the particular lead (or a lead alloy) platelattice.
