Electrolytic Cell
Another notable application of electrolytic cells is in electroplating, which is the process of forming a thin protective layer of a specific metal on the surface of another metal. The electrorefining of many non-ferrous metals is done with the help of electrolytic cells. Such electrochemical cells are also used in electrowinning processes.
How Lead-Acid Batteries Work
The working principle of a lead-acid battery is based on the chemical reaction between lead and sulfuric acid. 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:
