  • METHODS AND SYSTEM FOR MANUFACTURING LEAD BATTERY PLATES
    Publication number: 20150325858
    Abstract: Methods and a system for manufacturing a lead or lead alloy plate lattice for a lead-acid battery are described, comprising continuous extrusion of a melt of lead or lead alloy under temperatures lower by 10-100° C. than the melting point of lead, or the lead alloy, the extrudate being subsequently subjected to a flattening process under a temperature lower by more than at least 230° C. than the melting point of lead or the lead alloy, with a total draft rate less than 10%, and thereafter the extrudate may be processed so as to manufacture a plate lattice.
    Type: Application
