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.
In this research, the performance of lead-acid batteries with nanostructured electrodes was studied at 10 C at temperatures of 25, −20 and 40 °C in order to evaluate the efficiency and the effect of temperature on electrode morphology.
Such applications include automotive starting lighting and ignition (SLI) and battery-powered uninterruptable power supplies (UPS). Lead acid battery cell consists of spongy lead as the negative active material, lead dioxide as the positive active material, immersed in diluted sulfuric acid electrolyte, with lead as the current collector:
Heat issues, in particular, the temperature increase in a lead-acid battery during its charging has been undoubtedly a concern ever since this technology became used in practice, in particular in the automobile industry.
