Abstract：

The　practical　utilization　of　rechargeable　aqueous　zinc　metal　batteries　(AZMBs)　has　been　constrained　by　the　formation　of　zinc　dendrites　and　other　associated　issues.　This　article　introduces　lactose,　a　compound　rich　in　hydroxyl　groups,　as　an　electrolyte　additive　into　the　aqueous　solution　of　the　electrolyte　with　the　objective　of　suppressing　the　harmful　growth　of　zinc　dendrites.　The　lactose　additive,　with　its　strong　zincophilicity,　robust　intermolecular　hydrogen　bonding,　and　a　large　number　of　exposed　high　electronegativity　hydroxyl　groups,　enables　lactose　to　effectively　modulate　the　electrode/electrolyte　interface　in　a　dynamic　manner,　thereby　achieving　the　stability　and　reversibility　of　the　zinc　anode.　The　findings　presented　in　this　work　demonstrate　the　uniform　deposition　and　stripping　of　zinc　in　a　2　M　ZnSO4　electrolyte　with　the　addition　of　lactose,　thereby　enhancing　the　cycling　performance　of　Zn||Zn　batteries.　The　alteration　of　the　zinc　ion　environment　on　the　surface　of　the　zinc　electrode,　in　conjunction　with　the　dynamic　modulation　of　the　Gouy-Chapman-Stern　(GCS)　layer　by　lactose,　increases　the　nucleation　overpotential,　thereby　facilitating　to　a　uniform　deposition　morphology　in　lieu　of　the　formation　of　large-scale　dendrites.　Furthermore,　the　formation　of　hydrogen　bonds　serves　to　prevent　the　occurrence　of　side　reactions.　These　factors　act　in　concert　to　enhance　the　electrochemical　performance　of　AZMBs.　The　addition　of　lactose　to　the　electrolyte　has　resulted　in　a　significant　enhancement　in　the　Coulombic　efficiency　of　the　card-type　Zn||Cu　asymmetric　battery,　reaching　99.7　%.　The　biodegradability　of　lactose　and　the　sustainability　of　its　source　make　this　research　conducive　to　the　development　of　environmentally　friendly　battery　electrolyte　additives.　©　2024　Elsevier　B.V.
