Battery-Battery
Charge: concentration of electrolyte increases; inside resistance decrease; electromotive force of
battery increases, and there will be large quantity of air bubble generated because of the electrolysis
of water at the later period of charging.
General reaction of the battery
Active material on Active material on Generated by positive Generated by Generated by negative

Lead dioxide Thin sulfuric acid Lead Lead sulfate Water Lead sulfate
Active materials on both positive and negative poles will be converted to lead sulfate after battery is
discharged; this theory explained flow reaction of lead-acid battery is called as “dual Sulfation”
theory.
