What Is a Lead-Acid Battery and How Does It Function in Electric Vehicles?
A lead-acid battery is a rechargeable energy storage device that uses lead and lead oxide plates submerged in an electrolyte solution of sulfuric acid. It converts chemical energy into electrical energy through electrochemical reactions, primarily used in vehicles.
According to the International Energy Agency (IEA), lead-acid batteries are recognized for their reliability in providing high starting currents and energy storage capabilities. The U.S. Department of Energy also notes that these batteries are crucial for various applications, including electric and hybrid vehicles.
Lead-acid batteries function by undergoing oxidation and reduction reactions when charging and discharging. During discharge, lead (Pb) and lead dioxide (PbO2) react with sulfuric acid (H2SO4) to create lead sulfate (PbSO4) and release electrical energy. Recharging reverses this process, restoring the original materials.
The Battery University defines lead-acid batteries as the oldest type of rechargeable battery, offering low cost and maintenance.
Factors affecting lead-acid battery performance include temperature, charge cycles, and depth of discharge. Deeper discharges and high temperatures can shorten battery life significantly.

How Does the Electrochemical Reaction Generate Power in a Lead-Acid Battery?
The electrochemical reaction generates power in a lead-acid battery by converting chemical energy into electrical energy. This process occurs through two main reactions at the battery’s electrodes. The battery contains lead dioxide (PbO2) at the positive terminal and sponge lead (Pb) at the negative terminal, both immersed in a sulfuric acid (H2SO4) electrolyte.
When the battery discharges, the lead dioxide reacts with the electrolyte. This reaction produces lead sulfate (PbSO4) and releases electrons. At the same time, the sponge lead also reacts with the electrolyte, generating more lead sulfate and releasing additional electrons. These electrons flow through an external circuit, providing electrical power to connected devices.
During the charging process, an external power source applies current to the battery. This current reverses the electrochemical reactions. The lead sulfate decomposes back into lead dioxide and sponge lead, and the sulfuric acid electrolyte is restored. This restoration allows the battery to store energy for future use.
Overall, the electrochemical reactions in lead-acid batteries involve continuous cycling between chemical compounds. This cycling allows for the efficient conversion of chemical energy into usable electrical energy, thus generating power in lead-acid batteries.
