A plate making process for a lead acid battery which eliminates the need for steaming and curing steps to produce the active material. Mixing, reacting and crystallizing occur in a closed reactor under controlled temperature and mixing conditions to produce a paste having the desired crystal morphology. A polymer is then added to the paste to bind the crystals together and to produce desired ...

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.

1. Introduction. The compositions of leady oxide mainly contain 70%80% lead (II) oxide and 20%30% metallic lead with a small amount of other lead oxides [1].The two predominant methods used to produce leady oxides are the "ballmill process" where lead is heated and oxidized by the tumbling action or the "Bartonpot" method where atomized liquid droplets are oxidized.

The conversion of inert lead into a reactive lead oxide is the essence of creating the DNA of the leadacid battery. This process plays a key role in determining the performance, life and properties of the finished battery. The Barton pot process has some degree of flexibility that is missing with the ball mill method.

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. Red lead (Pb 3O 4) can also be added to the PbO formed by these methods, as it is more conductive. This is produced from PbO by roasting in a flow of air.
