Lead–acid batteries are comprised of a lead-dioxide cathode, a sponge metallic lead anode, and a sulfuric acid solution electrolyte. The widespread applications of lead–acid batteries include, among others, the traction, starting, lighting, and ignition in vehicles, called SLI batteries and stationary batteries for uninterruptable power supplies and PV systems.
It''s the real consequence of the chemical reaction for the battery discharge, where the lead (Pb) and the lead dioxide (PbO2), reacting with sulfuric acid (H2SO4) during the proceeding discharge, change in lead sulfate (PbSO4). The lead sulfate layer is unable to dissolve in water and this creates a real insulation layer between the battery''s tiles and the electrolite.
