AI Customer ServiceSuch 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:
The components in Lead-Acid battery includes; stacked cells, immersed in a dilute solution of sulfuric acid (H 2 SO 4), as an electrolyte, as the positive electrode in each cells comprises of lead dioxide (PbO2), and the negative electrode is made up of a sponge lead.
5.2.1 Voltage of lead acid battery upon charging. The charging reaction converts the lead sulfate at the negative electrode to lead. At the positive terminal the reaction converts the lead to lead oxide. As a by-product of this reaction, hydrogen is evolved.
A lead grid coated with lead dioxide forms the positive electrode. Charging the battery generates porous lead dioxide PbO2 at the anode and a lead sponge at the cathode. The electrolyte is 37% sulfuric acid (1.28 g cm −3). During discharging, sulfuric acid is consumed and water is formed, reducing the density to 1.18 g/cm 3 (25%).
Such a device operates through chemical reactions involving lead dioxide (cathode electrode), lead (anode electrode), and sulfuric acid . Lead-acid batteries have a high round-trip efficiency, and are cheap and easy to install.
In a sealed lead acid (SLA) battery, the hydrogen does not escape into the atmosphere but rather moves or migrates to the other electrode where it recombines (possibly assisted by a catalytic conversion process) to form water.
