Abstract
A method of producing lead alloy strip for fabrication of positive and negative electrodes of a lead-acid battery by extruding a lead alloy at elevated temperature to produce a lead alloy strip having a desired profile and rapidly cooling the extruded strip to acquire a desired microstructure. Battery grids produced from the lead alloy strip have reduced vertical growth and enhanced resistance to corrosion.
Claims13
A method of producing a lead alloy strip for battery electrodes comprising extruding a lead alloy through a die block to produce an extrusion having a desired shape and rapidly cooling the extrusion to acquire a lead alloy grain size in the range of about 10 to 300 microns.
