Abstract
A method of producing an electrical potential by way of a rechargeable battery with a positive electrode of lead and a negative electrode of highly pure zinc. The electrolyte is an aqueous solution of an alkali metal bisulfate. Upon discharge, lead dioxide is reduced to lead sulfate, zinc is oxidized to zinc oxide, and the electrolyte is converted to an alkali metal hydroxide. The reactions are reversed when the battery is charged.
Claims3
A method of producing a usable electric potential by way of a storage battery having both positive and negative electrodes and an electrolyte wherein the composition of the positive electrode is lead dioxide, the composition of the negative electrode is uncoated zinc in excess of 99.9% pure and the composition of the electrolyte is an aqueous solution of an alkali metal bisulfate, wherein the method comprises the step of discharging the battery such that the positive electrode is reduced to divalent lead sulfate, the negative electrode is oxidized and the electrolyte is concerted to an alkali metal hydroxide wherein the discharge reaction is represented by the formula:
- PbO2+NaHSO4+Zn→PbSO4+ZnO+NaOH.
