Alloy for use in manufacturing grid plates for batteries of lead - acid battery, process for manufacture of said bars and grid plate produced by the process of battery.

摘要

Battery plate grids for lead-acid batteries are manufactured from an alloy having the following composition in atomic percentages:- }Calcium + Lithium 0.22 - 1.04 }Aluminium 0.035 - 0.25 }Lead remainder, } WHEREIN THE ATOMIC PERCENTAGE OF LITHIUM IN THE ALLOY IS NOT LESS THAN 0.15 AND DOES NOT EXCEEDS 0.90 AND THE ATOMIC PERCENTAGE OF CALCIUM IN THE ALLOY IS NOT LESS THAN 0.07 AND DOES NOT EXCEED 0.49.
