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:
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 structure and properties of the positive active material PbO 2 are key factors affecting the performance of lead–acid batteries. To improve the cycle life and specific capacity of lead–acid batteries, a chitosan (CS)-modified PbO 2 –CS–F cathode material is prepared by electrodeposition in a lead methanesulfonate system.
The active mass was obtained from lead powder made in a Barton pot. XRD analysis of lead dust showed that the used material consisted of 71.4% α - PbO, 4.6% β - PbO, and 24.0% Pb, in relative percent. This composition confirmed that the physicochemical parameters were appropriate for use in the lead-acid battery industry.
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.
One of the singular advantages of lead acid batteries is that they are the most commonly used form of battery for most rechargeable battery applications (for example, in starting car engines), and therefore have a well-established established, mature technology base.

The lead–acid cell can be demonstrated using sheet lead plates for the two electrodes. However, such a construction produces only around one ampere for roughly postcard-sized plates, and for only a few minutes. Gaston Planté found a way to provide a much larger effective surface area. In Planté''s design, the positive and negative plates were formed of two spirals o…
