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.
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.
Depending on the pH, i.e. the presence of sulfuric acid or sulfate, lead oxide or one of lead sulfates de-scribed above are the most favorable compounds. Both lead dioxide and metallic lead, the final active materi-als in the lead-acid battery, are on a higher energy level.
At its core, a lead-acid battery is an electrochemical device that converts chemical energy into electrical energy. The battery consists of two lead plates, one coated with lead dioxide and the other with pure lead, immersed in an electrolyte solution of sulfuric acid and water.
A lead-acid battery stores energy through a chemical reaction that takes place between lead and lead dioxide plates and sulfuric acid electrolyte. The energy is stored in the form of potential difference or voltage between the two electrodes.
The battery should not, therefore, be discharged below this voltage. In between the fully discharged and charged states, a lead acid battery will experience a gradual reduction in the voltage. Voltage level is commonly used to indicate a battery's state of charge.
