There are two principal methods of making leady oxide for lead/acid batteries. These are: (i) the Barton-pot process, which utilizes the oxidation of molten lead; (ii) the ball-mill process, which employs the oxidation of solid lead. Several conflicting claims have been made for the advantages of the one process over the other, and vice versa.

The aim of this research is to prepare leady oxide with high specific area for lead–acid batteries by a new production process. Leady oxide is produced by a cementation reaction in 1.0 wt% HCl solution using a pure aluminum or a magnesium rod as the reductant. Leady oxide prepared in this process is much superior to Barton-pot or …

In the ball-mill process, the friction of lead balls tumbling against one another inside the mill chamber create sufficient heat to oxidize their surfaces. As attrition and oxidation wear the balls down, new ones are added. The degree of product oxidation is primarily a function of air flow through the system and, to a lesser degree, the ...
