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.
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.
A lead acid battery consists of a negative electrode made of spongy or porous lead. The lead is porous to facilitate the formation and dissolution of lead. The positive electrode consists of lead oxide. Both electrodes are immersed in a electrolytic solution of sulfuric acid and water.
Lead acid batteries store energy by the reversible chemical reaction shown below. The overall chemical reaction is: P b O 2 + P b + 2 H 2 S O 4 ⇔ c h a r g e d i s c h a r g e 2 P b S O 4 + 2 H 2 O At the negative terminal the charge and discharge reactions are: P b + S O 4 2 - ⇔ c h a r g e d i s c h a r g e P b S O 4 + 2 e -
A plug is inserted which is linked to the lead-acid battery and the chemical reaction proceeds in the opposite direction. In cases where the sulphuric acid in the battery (or some other component of the battery) has undergone decomposition, the charging process may become inefficient. Therefore, it is advisable to check the battery periodically.
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. During the first part of the charging cycle, the conversion of lead sulfate to lead and lead oxide is the dominant reaction.
During discharge, at the "−" plate, the lead is oxidized from metallic Pb to divalent Pb (II). This liberates negative charge into the "−" plate. Meanwhile, at the "+" plate, the lead is reduced from tetravalent Pb (IV) to divalent Pb (II).
