Zusammenfassung:Provided is a secondary electrochemical cell for storing and delivery electrical energy and method of forming same. The secondary electrochemical cell includes: a thin film zinc metal negative electrode comprising a negative electrode current collector and a zinc metal layer applied to the negative electrode current collector; a thin film positive electrode comprising a positive electrode current collector and an active material layer applied to the positive electrode current collector, wherein the active material layer electrochemically reacts reversibly with Zn2+ cations; an aqueous electrolyte ionically coupling the negative electrode to the positive electrode; and a thin separator disposed between the negative electrode and the positive electrode, wherein the separator is wetted by the aqueous electrolyte.
