Original Abstract
In a lead-acid cell the active materials there are lead dioxide in the positive plate, sponge lead in the negative plate, and a solution of sulphuric acid in water as the electrolyte. A chemical reaction proceeds place between lead plates and sulphuric acid, producing electric current. When the charge is depleted, the battery can be recharged many times. When the battery is electrically charged, the sulphate ions in the sulphuric acid react with the positive and negative plates, forming lead sulphate. Electrons from the reaction flow out from the negative terminal to the circuit and then back into the positive side. When the battery is charging, the lead sulphate leaves the electrodes and transforms into the sulphuric acid again. The discharge-charge cycle can be repeated thousands of times.
