Lead-Acid Battery Basics
Lead-Acid Battery Cells and Discharging. A lead-acid battery cell consists of a positive electrode made of lead dioxide (PbO 2) and a negative electrode made of porous metallic lead (Pb), both of which are immersed in a sulfuric acid (H 2 SO 4) water solution. This solution forms an electrolyte with free (H+ and SO42-) ions.
Understanding Cell and Battery Construction
Older lead-acid batteries were made from cast lead plates onto which a paste was loaded. These plates and separators were then stacked, generally with negative plates on both sides, so there was always one more negative plate than the positive plate. Batteries were often called 7-plate, 9-plate, or as many as 17-plate batteries.
Lead Battery Recycling Process
Lead batteries reign as the most recycled consumer product in the U.S. today and the most sustainable battery technology; 99% of lead batteries are safely recycled in an established, coast-to-coast network of advanced recycling facilities.

Which Gases Are Produced In Battery Charging?
Lead-acid batteries will produce little or no gases at all during discharge. During discharge, the plates are mainly lead and lead oxide while the electrolyte has a high concentration of sulfuric acid. During discharge, the sulfuric acid in the electrolyte divides into sulfur ions and hydrogen ions.
