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.
The chemistry of lead-acid batteries involves oxidation and reduction reactions. During discharge, lead dioxide and sponge lead react with sulfuric acid to produce lead sulfate (PbSO4) and water. When recharged, the process is reversed, regenerating lead dioxide, sponge lead, and sulfuric acid.
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.
Following are some of the important applications of lead – acid batteries : As standby units in the distribution network. In the Uninterrupted Power Supplies (UPS). In the telephone system. In the railway signaling. In the battery operated vehicles. In the automobiles for starting and lighting.
Cost: Lead acid batteries are more affordable upfront than lithium-ion batteries. The average cost of lead acid batteries can be about $150-$200 per kWh, while lithium-ion batteries average around $300-$700 per kWh. This cost advantage makes lead acid batteries a popular choice for budget-conscious applications.
Efficiency: Lead acid batteries typically operate at about 70-80% efficiency. This means that a portion of the energy is lost as heat during the conversion processes. Applications: Lead acid batteries are widely used in automobiles, uninterruptible power supplies, and renewable energy storage systems.
