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:
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.
The lead-acid battery electrolyte and active mass of the positive electrode were modified by addition of four ammonium-based ionic liquids. In the first part of the experiment, parameters such as corrosion potential and current, polarization resistance, electrolyte conductivity, and stability were studied.
The positive electrode of the LAB consists of a combination of PbO and Pb 3 O 4. The active mass of the positive electrode is mostly transformed into two forms of lead sulfate during the curing process (hydro setting; 90%–95% relative humidity): 3PbO·PbSO 4 ·H 2 O (3BS) and 4PbO·PbSO 4 ·H 2 O (4BS).
Lead, tin, and calcium were the three main components. Other elements constitute ~0.02 wt% of the sample. Corrosion potential and current, polarization resistance, electrolyte conductivity, and stability were studied. IL was selected as an effective additive for capacity tests of the positive electrode.
Lead carbon battery, prepared by adding carbon material to the negative electrode of lead acid battery, inhibits the sulfation problem of the negative electrode effectively, which makes the problem of positive electrode become more prominent.
