4.1 General
The reaction (4) in discharge, i.e. read from left to right, involves 2 faradays. We check that 3.86 g of lead, 4.46 g of lead dioxide and 3.66 g of sulfuric acid should theoretically provide 1 Ah. In fact, this is not the case, because the further away the positive active material is from the faces of the plate wetted by the acid, the less it is used, and the higher the discharge rate. As a molecule of lead dioxide is transformed into a molecule of lead sulfate during discharge, the local transformation rate τ(M) is defined as the ratio, for an infinitesimal volume element surrounding...
