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.
The positive active-material of lead–acid batteries is lead dioxide. During discharge, part of the material is reduced to lead sulfate; the reaction is reversed on charging. There are three types of positive electrodes: Planté, tubular and flat plates.
Negative plates in all lead-acid cells are the flat pasted type. The Manchex type is shown in Figure 3-1. The grid is cast with low antimony lead alloy. The button or rosette is a pure lead ribbon which is serrated and rolled into a spiral form. These in turn are pressed or wedged into the holes of the grid.
The process results in a lead dioxide layer with a thickness of between 0.1 and 0.2 mm. There is more active-material at the tips of the ribs because the local current density during formation is higher than that at the bottom of the grooves. The porosity is >60%, which is rather high for positive active-material.
For most lead-acid battery subsystems it is necessary that they be charged by voltage regulator circuits properly compensated for changes in operating temperature. The number of cells in series is obtained by dividing the maximum system charge voltage by the maximum charge voltage in volts per cell specified by the cell manufacturer.
The lead used for the production of the active-material should have a very high purity with low levels of elements that would increase hydrogen gassing at the negative electrode. This requirement is especially important for VRLA batteries.
