Why Lead Acid Battery Has More Negative Plates Than Positive Plates?
However, the most common lead acid battery used in cars and trucks has a positive plate made of lead dioxide and a negative plate made of sponge lead. The reason for this is that the lead dioxide can better withstand the repeated charging and discharging cycles that occur in automotive applications.
The lead acid battery is made up of two plates, the positive plate, and the negative plate. These plates are made of lead and separated by an electrolyte. The lead acid battery has a high energy density and can be discharged and recharged many times.
Discharge Process During the discharge process, the lead and lead oxide plates in the battery react with the sulfuric acid electrolyte to produce lead sulfate and water. The chemical reaction can be represented as follows: Pb + PbO2 + 2H2SO4 → 2PbSO4 + 2H2O ...
