Abstract
Rechargeable batteries and corresponding methods are provided, in which zinc dendrite growth to a compartment between a zinc-based anode and a separator of a rechargeable battery is limited, by preventing zincate anions from diffusing outside of the compartment. Separators limiting dendrite growth may comprise ion-selective membrane(s) configured to be permeable to charge transfer cations of the alkaline electrolyte and impermeable to hydrated zincate anions. The membrane(s) may be reinforced and/or support internal compartment(s) with electrolyte lacking zincate ions. More generally, separators are provided, which are permeable to charge transfer ions but impermeable to metal ions, and limit the latter to the anode compartment in which the metal ions may be deposited in a manner that does not form dendrites which can compromise the structural and functional integrity of the battery cell.
