Functions of Sulfuric Acid in Battery Chemistry:
In battery chemistry, sulfuric acid acts as an electrolyte, creating a conductive medium for the movement of ions. An electrolyte is a substance that produces an electrically conducting solution when dissolved in a solvent like water. In lead-acid batteries, the sulfuric acid is mixed with water to form a dilute acid solution, usually in a concentration of about 30-37%.
Sulfuric acid facilitates ion transfer within the battery. During discharge, lead dioxide (PbO2) at the positive plate and sponge lead (Pb) at the negative plate react with sulfuric acid. This reaction generates sulfate ions, which move through the electrolyte, allowing the battery to produce electrical energy. When the battery is charged, the process reverses, and the sulfate ions are converted back to lead dioxide and sponge lead.
The interaction of sulfuric acid with the lead plates also supports the formation of lead dioxide and sponge lead. This construction is essential for the battery’s operation. The conversion of lead sulfate back to lead and lead dioxide during charging is crucial for battery lifespan.
Additionally, sulfuric acid influences the voltage levels in the battery. The voltage of a fully charged lead-acid battery is typically around 2.1 volts per cell, achieved through the concentration of sulfuric acid in the electrolyte. Variations in acid concentration can lead to differences in battery performance, including its capacity and discharge rates.
Numerous studies highlight the performance impact of sulfuric acid in lead-acid batteries. In a research paper by T. S. G.
