Zinc　(Zn)　metal　is　regarded　as　a　promising　anode　material　for　aqueous　batteries　owing　to　its　high　natural　abundance,　high　theoretical　capacity　and　low　redox　potential.　However,　aqueous　Zn　metal　anodes　suffer　from　poor　reversibility,　as　shown　by　their　low　Coulombic　efficiency　(CE)　and　dendrite　growth　during　long-term　plating/stripping.　In　this　study,　we　report　that　a　thin　metallic　Cu　or　Ag　interfacial　layer,　made　by　a　facile　thermal　evaporation　method,　can　enable　highly　reversible　and　nondendritic　plating/stripping　of　Zn　metal　anodes　in　aqueous　batteries.　This　is　attributed　to　the　synergy　of　fast　Zn-ion　migration　through　the　tiny　gaps　in　the　interfacial　layer　as　well　as　its　high　interfacial　affinity　for　Zn　metal.　High　average　CE　of　99.7%　are　achieved　over　3000　plating/stripping　cycles　at　10　mA　cm-2　and　1　mAh　cm-2.　The　modified　Zn　anode　can　stably　cycle　for　more　than　2500　cycles　(5000　h)　of　plating/stripping　at　1　mA　cm-2　and　a　500　cycle-life　is　realized　for　a　full　cell　paired　with　a　MnO2　cathode.　This　finding　opens　up　a　promising　avenue　to　develop　the　next-generation　Zn　metal-based　energy　storage　technologies.
