Zinc-air cells have been developed that are capable of delivering over 50 cycles. These cells were constructed with silver-amalgam air-cathodes, nickel screen charging electrodes, and teflonated zinc anodes. The major failure modes encountered in this study were shorting by zinc penetration, loss of capacity by the zinc anode due to edge-corrosion and surface densification, platinum poisoning of the zinc anode when employing platinum-catalyzed air- cathodes, and passivation of the zinc anode by electrolyte starvation. The means of overcoming these problems are presented.
