how to work Lead Storage battery
Answers
Camille Alphonse Faure’s pasted-plate construction is typical of automotive batteries today. Each plate consists of a rectangular lead grid. The holes of the grid are filled with a paste of red lead and 33 percent dilute sulfuric acid. This porous paste allows the acid to react with the lead inside the plate, which increases the surface area. Once dry, the plates are stacked with suitable separators and inserted into the battery container. An odd number of plates is usually used, with one more negative plate than positive. Each alternate plate is connected.
The paste contains carbon black, barium sulfate, and lignosulfonate. The barium sulfate acts as a seed crystal for the lead-to-lead sulfate reaction. The lignosulfonate prevents the negative plate from forming a solid mass during the discharge cycle, and instead enables the formation of long needle-like crystals. Carbon black counteracts the effect of inhibiting formation caused by the lignosulfonates.
