Abstract
A rechargeable battery is provided with a positive electrode of tin, a negative electrode of zinc and an alkaline electrolyte. Upon charging, some tin is converted to stannic oxide, and zinc oxide is reduced to zinc. When the battery is discharged, stannic oxide is reduced to stannous oxide and zinc is oxidized to zinc oxide.
