The positive and negative plates are made of lead and lead dioxide, respectively. They are immersed in an electrolyte solution made of sulfuric acid and water. Electrolyte Solution
A typical lead-acid battery contains six plates per cell. Most lead-acid batteries are made up of six cells connected in series, resulting in a standard configuration of 36 plates
Positive Plate: Made of lead dioxide (PbO₂), it serves as the cathode. Negative Plate : Made of sponge lead (Pb), it serves as the anode. Separators : Porous synthetic
In a lead-acid cell the active materials are lead dioxide (PbO2) in the positive plate, sponge lead (Pb) in the negative plate, and a solution of sulfuric acid (H2SO4) in water as the electrolyte.
Most lead–acid batteries are comprised of stacks of alternating positive and negative flat pasted plates that are interleaved with separators. Over the years, there has been a
A lead-acid battery consists of a series of positive and negative electrodes, or plates, immersed in an electrolyte solution. When the battery is discharged, the chemical reaction between the electrodes and the electrolyte produces electrical energy.

The positive plate contains a larger surface area of lead oxide than the negative plate, so it needs more space. In addition, the positive plate produces hydrogen gas during charging, so it must be vented to prevent pressure build-up. Lead acid batteries are one of the most popular types of batteries on the market today.
