Abstract : Rechargeable alkaline zinc batteries have been investigated heretofore as power sources capable of high energy density applications. One of the major problems with their use is the short circuiting of the unit cells by growth of zinc dendrites from the anode to the cathode during the charging of the battery. The general object of the patent is to overcome the problem of zinc penetration in alkaline zinc cells as in a long-lived high energy density rechargeable alkaline zinc-air cell. This is done by providing a flat zinc anode positioned intermediate of and spaced from a pair of flat air cathodes. Means are further provided to transport electrolyte to the electrodes.
