Operation of Lead Acid Batteries
The formation of this lead sulfate uses sulfate from the sulfuric acid electrolyte surrounding the battery. As a result, the electrolyte becomes less concentrated. Full discharge would result in both electrodes being covered with lead sulfate and water rather than sulfuric acid surrounding the electrodes.
What Is Battery Acid? Sulfuric Acid Facts
Battery acid (AKA sulfuric acid) is used in lead-acid batteries to help create and store electrical energy, which powers many devices and vehicles. Concentration less than 29% or 4.2 mol/L: The common name is dilute sulfuric acid. 29-32% or 4.2-5.0 mol/L: This is the concentration of battery acid found in lead-acid batteries. ...
LEAD-ACID STORAGE CELL
lead-acid cell is an electrochemical cell, typically, comprising of a lead grid as an anode and a second lead grid coated with lead oxide, as a cathode, immersed in sulfuric acid. The concentration of sulfuric acid in a fully charged auto battery measures a specific 1 2,3 gravity of 1.265 – 1.285.
