A lead alloy is described that is capable of manufacturing a positive electrode for a lead storage battery with a reduced likelihood of causing growth. The lead alloy contains 0.4% by mass or more and 2% by mass or less of tin and 0.004% by mass or less of bismuth, with the balance being lead and inevitable impurities. The diffraction intensity of a Cube orientation {001} <100> in a pole figure created by analyzing the surface of the lead alloy by an X-ray diffraction method is 4 times or less the diffraction intensity of a random orientation in a pole figure created by analyzing a pure lead powder by the X-ray diffraction method.

A lead alloy is described that is capable of manufacturing a positive electrode for a lead storage battery less likely to cause corrosion penetrating through a lead layer for the positive electrode in the thickness direction. The lead alloy contains 0.4% by mass or more and 2% by mass less of tin and 0.004% by mass or less of bismuth, with the balance being lead and inevitable impurities. When image analysis of a crystal orientation distribution map created by analyzing the surface of the lead alloy by an electron backscatter diffraction method is performed, intersection points of misorientation boundaries between crystal grains with a crystal misorientation of 5° or more and a straight line extending in one specific direction are extracted. The distances between two adjacent intersection points among the extracted intersection points are measured, and the average value of the distances is 50 μm or less.

A lead alloy usable to manufacture a lead storage battery electrode the with easily predictable growth is described. The diffraction intensity determined by analyzing the surface of the lead alloy in a crystal orientation {211}<111> in a pole figure using an X-ray diffraction method is five or less times the diffraction intensity determined by analyzing powder of pure lead in a random orientation in a pole figure using the X-ray diffraction method.

A lead alloy that is difficult to cause extension even when force is applied to the lead alloy is described. The half width of a (311) diffraction peak in a diffraction chart obtained by analyzing the lead alloy using an X-ray diffraction method is 1.4 or more times the half width of a (311) diffraction peak in a diffraction chart obtained by analyzing powder of pure lead using the X-ray diffraction method.

A method of making battery plates of pure lead battery grids for lead-acid battery manufacture is presented. The method has been shown to resolve issues that have long-persisted in the battery manufacture industry involving the use of pure lead material for battery grids. According to an implementation, several processes are performed in succession in order to make pure lead battery grids feasible in commercial and mass production, among them: a continuous casting process to produce battery grids of pure lead material, a compression rolling process of the cast pure lead battery grids, and a battery paste application process to the cast and rolled pure lead battery grids. The pure lead material of the continuous strip of pure lead battery grids can consist of lead (Pb) material in an amount that ranges approximately between 99.85 percent (%) to 99.999% of the overall constituent elements of the pure lead material.
