As one of the most mature battery systems, the silver-zinc battery holds huge promise in the field of aqueous rechargeable batteries due to superior performance, high safety and environmental friendliness. It is urgent to improve the areal capacity of silver-zinc batteries so far. This study reports a novel Cu-supported Ag Nanowires (Cu@AgNAs1-5: abbreviation of Cu@AgNAs1, Cu@AgNAs2, Cu@AgNAs3, Cu@AgNAs4 and Cu@AgNAs5) as binder-free cathodes for high performance rechargeable aqueous silver-zinc batteries. Cu@AgNAs1-5 are successfully prepared by two steps of electrochemical nanoengineering an...
