6 FAQs about [Electrode potential of lead-acid battery]

What is a lead acid battery cell?

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:

What happens when a lead acid battery is charged?

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.

How do you determine the cell potential of a lead acid cell?

Verify the effect of Temperature on the Cell Potential of the lead acid cell. Verify the effect of Activity (or concentration) of reacting species on the Cell Potential of the lead acid cell. Examine the effect of Electrode Composition on the Cell Potential of the lead acid cell.

How do lead-acid batteries work?

Battery Application & Technology All lead-acid batteries operate on the same fundamental reactions. As the battery discharges, the active materials in the electrodes (lead dioxide in the positive electrode and sponge lead in the negative electrode) react with sulfuric acid in the electrolyte to form lead sulfate and water.

How does a flooded lead acid battery work?

Electrode potentials and cell voltage for a typical flooded lead–acid battery As charging proceeds, the potentials keep gradually increasing until end of charge is reached. At this point, all lead sulfate is converted to lead on the negative electrode and to lead dioxide on the positive; and the charge is complete.

Why is the discharge state more stable for lead–acid batteries?

The discharge state is more stable for lead–acid batteries because lead, on the negative electrode, and lead dioxide on the positive are unstable in sulfuric acid. Therefore, the chemical (not electrochemical) decomposition of lead and lead dioxide in sulfuric acid will proceed even without a load between the electrodes.
