Abstract
Melting and recrystallizing the surfaces of a wrought Pb--Ca--Sn alloy strip from which positive Pb-acid storage battery grids are punched or expanded. The alloy also contains an alloyant such as silver which, upon recrystallization, provides a higher concentration of alloyant-rich grain boundaries on the surface of the grid than the wrought grid for enhancing the conductivity of any oxidation layer formed on the surface of the grid during high temperature cycling of the battery.
