The electrolyte is then free to enter all the tiny holes in the sponge, thereby increasing the effective capacity of the battery. The negative and positive lead battery plates conduct the energy during charging and discharging. This pasted plate design is the generally accepted benchmark for lead battery plates.
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 negative plate collects the electrons from the electrolyte, becoming negatively charged in the process. The positive plate, on the other hand, collects the positively charged ions from the electrolyte, giving up an electron to each ion and therefore becoming positively charged in the process.
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.
Positive plates were taken from a standard battery. These cells achieved good capacity, about 135–155 Ah per kilogram of NAM. Obtained Peukert coefficients were comparable to values reached by commercial batteries. A discharge using currents in the 0.05–1C range did not show significant differences between two types of negative collectors.
UltraBattery, developed by Australian Commonwealth Scientific and Industrial Research Organization, is an example of such an asymmetric battery with negative plate comprised of two parts: carbon capacitor and standard plate .
