Care & Maintenance of Lead Acid Batteries
Electrolyte of Lead Acid Battery. The electrolyte of a lead acid battery cell is a solution of sulfuric acid and distilled water. The specific gravity of pure sulfuric acid is about 1.84 and this pure acid is diluted by distilled water until the specific gravity of the solution becomes 1.2 to 1.23.
Flooded lead-acid batteries
While lead-acid batteries may not offer the high energy density or lifespan of some other battery technologies, their proven reliability and cost-effectiveness continue to make them a preferred choice in many industries, from automotive to renewable energy, providing a dependable and accessible source of stored energy.
6.10.1: Lead/acid batteries
The lead acid battery uses lead as the anode and lead dioxide as the cathode, with an acid electrolyte. The following half-cell reactions take place inside the cell during discharge: At the anode: Pb + HSO 4 – → PbSO 4 + H + + 2e – At the cathode: PbO 2 + 3H + + HSO 4 – + 2e – → PbSO 4 + 2H 2 O. Overall: Pb + PbO 2 +2H 2 SO 4 → ...
