Abstract

An alkaline battery comprises an anode, a cathode, a separator disposed between the anode and the cathode, and an electrolyte in fluid communication with the anode, the cathode, and the separator. The separator comprises at least one ion selective layer that can include at least one of graphene, graphene oxide, reduced graphene oxide, functionalized graphene, or combinations thereof. This can allow the ion selective layer to be configured to selectively block zincate ions.
