Abstract
In the manufacture of lead acid battery electrodes, the oxidation of lead, particularly recycled lead containing silver, is enhanced by addition of magnesium to the lead. During the production of the lead acid battery, at least about 0.001 weight percent of magnesium is formed into an alloy with lead. The resulting alloy is then subjected to oxidizing conditions. The alloy may further contain silver.
