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.
In the case of a lead-acid battery, the chemical reaction involves the conversion of lead and lead dioxide electrodes into lead sulfate and water. The sulfuric acid electrolyte in the battery provides the medium for the transfer of electrons between the electrodes, resulting in the generation of electrical energy.
A lead-acid battery is made up of several components that work together to produce electrical energy. These components include: 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.
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.
Lead-acid batteries are prone to a phenomenon called sulfation, which occurs when the lead plates in the battery react with the sulfuric acid electrolyte to form lead sulfate (PbSO4). Over time, these lead sulfate crystals can build up on the plates, reducing the battery’s capacity and eventually rendering it unusable.
