Method of making plates with pure lead grids for lead-acid battery manufacture

A method of making battery plates of pure lead battery grids for lead-acid battery manufacture, the method comprising:

• continuously casting a continuous strip of pure lead battery grids to produce a cast continuous strip of pure lead battery grids, the cast continuous strip of pure lead battery grids composed of a pure lead material, the pure lead material comprising lead (Pb) in an amount of approximately 99.85 percent (%) to 99.999% of overall constituent elements of the pure lead material;
• advancing the cast continuous strip of pure lead battery grids through at least one pair of compression rollers under cold-working conditions in order to reduce a thickness dimension of the cast continuous strip of pure lead battery grids and to impart hardness to the cast continuous strip of pure lead battery grids, producing a cast and rolled continuous strip of pure lead battery grids, wherein the cold-working conditions involves providing the cast continuous strip of pure lead battery grids at a metal temperature thereof that ranges between approximately 35 degrees Fahrenheit (° F.) to 180° F. prior to advancing the cast continuous strip of pure lead battery grids through the at least one pair of compression rollers;
• and
• applying an electrochemically-active battery paste material to the cast and rolled continuous strip of pure lead battery grids.

• and
• applying an electrochemically-active battery paste material to the cast and rolled continuous strip of pure lead battery grids.
