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.
Claims18
A method of enhancing the oxidation of lead during production of lead-acid batteries comprising alloying at least about 0.001 weight percent magnesium with the lead and subjecting the resulting alloy to oxidizing conditions.
In a method of oxidizing lead used in production of lead-acid batteries, the improvement comprising effecting oxidation after alloying at least about 0.001 weight percent magnesium into the lead.
A method of producing lead oxide from lead alloys containing silver for use in a lead acid battery electrode comprising alloying magnesium into the silver-containing lead and subjecting the resultant alloy to oxidizing conditions.
The method of claim where the magnesium content of the lead is at least about 0.001 weight percent.
