How Does Lead-Acid Batteries Work?

Lead-Acid Battery Composition. A lead-acid battery is made up of several components that work together to produce electrical energy. These components include: Positive and Negative Plates. The positive and negative plates are made of lead and lead dioxide, respectively. They are immersed in an electrolyte solution made of sulfuric acid and water.

Lead–acid battery

Overcharging with high charging voltages generates oxygen and hydrogen gas by electrolysis of water, which bubbles out and is lost. The design of some types of lead–acid battery (eg "flooded", but not VRLA (AGM or gel)) allows the electrolyte level to be inspected and topped up with pure water to replace any that has been lost this way.

In the discharged state, both the positive and negative plates become lead(II) sulfate (PbSO 4), and the electrolyte loses much of its dissolved sulfuric acid and becomes primarily water. Negative plate reaction Pb(s) + HSO 4(aq) → PbSO 4(s) + H (aq) + 2e The release of two conduction electrons gives the lead electrode a negative charge. As electrons accumulate, they create an electric field which attracts hydrogen ions and repels s

6.10.1: Lead/acid batteries
