Keywords: Lead/acid battery: Positive plate; Leady oxide; Barton pot; Ball mill 1. Lead and its oxides The atomic structure of lead has four valency electrons, two of which are in the 6p and two in the 6s orbitals. Because the orbitais are only partially filled, lead can form a wide variety of oxides.

During the last decade numerous protocols have been published using the method of ball milling for synthesis all over the field of organic chemistry. However, compared to other methods leaving their marks on the road to sustainable synthesis ( microwave, ultrasound, ionic liquids) chemistry in ball mills is rather underrepresented in the knowledge of organic chemists.

The acid absorption of oxide from Barton pot reactors is only between 160 and 180, whereas ball mills produce a dust with a higher acid absorption: 220260 mg of sulfuric acid per gram of oxide. Therefore, the solution is to produce lead oxide with ball mills, right? Correct, but let's look a little more deeply into this matter.

Barton pot: A fine stream of molten lead is inserted into a heated vessel. Each droplet reacts with the air to form an oxide layer, giving 70 85% lead oxide. Ball milling: Pieces of lead are put into a rotary mechanical mill, forming fine lead flakes, which are then oxidised in air and removed. This also gives 75 80% lead oxide.

There are two principal methods of making leady oxide for lead/acid batteries. These are: (i) the Bartonpot process, which utilizes the oxidation of molten lead; (ii) the ballmill 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.
