Battery Application & Technology All lead-acid batteries operate on the same fundamental reactions. As the battery discharges, the active materials in the electrodes (lead dioxide in the positive electrode and sponge lead in the negative electrode) react with sulfuric acid in the electrolyte to form lead sulfate and water.
Such applications include automotive starting lighting and ignition (SLI) and battery-powered uninterruptable power supplies (UPS). Lead acid battery cell consists of spongy lead as the negative active material, lead dioxide as the positive active material, immersed in diluted sulfuric acid electrolyte, with lead as the current collector:
In addition, the large size of lead sulfate crystals leads to active material disjoining from the plates. Due to the production of hydrogen at the positive electrode, lead acid batteries suffer from water loss during overcharge.
Due to the production of hydrogen at the positive electrode, lead acid batteries suffer from water loss during overcharge. To deal with this problem, distilled water may be added to the battery as is typically done for flooded lead acid batteries.
On recharge, the lead sulfate on both electrodes converts back to lead dioxide (positive) and sponge lead (negative), and the sulfate ions (SO 42 ) are driven back into the electrolyte solution to form sulfuric acid. The reactions involved in the cell follow. At the positive electrode: At the negative electrode: Over cell:
Using this principle, during a positive pulse, a larger voltage value is applied to the battery, which can break the lead sulfate crystal attached to the electrode plate and turn it into lead sulfate that can participate in the charging reaction.
It is important to understand what happens during the charging process when a battery is already fully charged. That means all PbSO 4 from both electrodes is converted to …
