A novel ultrafine leady oxide prepared from spent lead pastes for application as cathode of lead acid battery. 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. BEST technical editor, Dr ...

The ball mill process converts solid lead pieces directly into oxide through attrition by causing them to rub against each other within a rotating reactor or ball mill. The lead in the ball mill is the grinding media as well as a reactant. The particles or agglomerates produced by the molten lead Barton process are droplike or spherical whereas ...
