外文摘要：The main bottleneck of aqueous zinc metal anodes is the limited cycle lifespans stemming from severe dendrite formation and fragile interfaces. Herein, we fabricated a silver paste protective layer on a Zn substrate surface via a spray-coating technique, creating a versatile interphase that enables highly reversible and corrosion-resistant Zn anodes. The commercial silver paste, composed mainly of Ag and Cu particles, forms a zincophilic composite layer that facilitates uniform Zn-ion flux. The Ag/Cu surface could effectively suppress the hydrogen evolution reaction due to the high hydrogen evolution barrier, thereby suppressing interfacial side reactions caused by water. Notably, the Ag-Zn and Cu-Zn alloys formed during the early plating/stripping processes regulate zinc nucleation without dendrite formation and facilitate ion transfer in subsequent cycles, contributing to improved coulombic efficiency and extended cycling durability. The Zn@SP symmetric cell exhibits remarkable longevity, maintaining stable operation for 3500 h at 0.5 mA cm-2 (0.5 mA h cm-2). When paired with a V2O5 cathode, the full cell incorporating the Zn@SP anode showcases outstanding rate capability and cycling performance. This economical silver paste combined with the facile and scalable spray-coating method presents a viable pathway towards commercializing high-performance metal anodes.
