In the charged state, the positive active-material of the lead–acid battery is highly porous lead dioxide (PbO 2). During discharge, this material is partly reduced to lead sulfate. In the early days of lead–acid battery manufacture, an electrochemical process was used to form the positive active-material from cast plates of pure lead.
In the early days of lead–acid battery manufacture, an electrochemical process was used to form the positive active-material from cast plates of pure lead. Whereas this so-called ‘Planté plate’ is still in demand today for certain battery types, flat and tubular geometries have become the two major designs of positive electrode.

W hen Gaston Planté invented the lead–acid battery more than 160 years ago, he could not have fore-seen it spurring a multibillion-dol- lar industry.
