What Is the Main Material Used to Make Lead-acid Batteries?

The main materials used to make lead-acid batteries are lead and sulfuric acid.

  1. Lead: Lead is the primary material used for the electrodes in lead-acid batteries. It is commonly used due to its ability to conduct electricity and its durability. Lead is used in various forms within the battery, including lead dioxide (PbO2) for the positive plate and sponge lead (Pb) for the negative plate.
  2. Sulfuric Acid: Sulfuric acid (H2SO4) is used as the electrolyte in lead-acid batteries. It plays a crucial role in the electrochemical reactions that occur within the battery during charging and discharging processes.

These two materials, lead and sulfuric acid, along with other components such as separators and casings, are combined to create the cells and overall structure of lead-acid batteries.
