Abstract Interfacial stress caused by semi‐coherent and incoherent interfaces during zinc (Zn) plating its effect on subsequent Zn deposition are important considerations for designing electrode/electrolyte to improve the electrochemical performance of anodes. Although some studies have paid attention this issue, influence lattice strain induced ion diffusion in interface coating is infrequently discussed. Herein, a tin‐doped indium oxide (ITO) interfacial constructed, evolution oxygen vacancy (O V ) generated migration confirmed. The formed O ‐rich ITO exhibits strong affinity low barrier, accelerating transport kinetics. Meanwhile, layer can appropriately capture anions electrolyte corrosion resistance electrode through electrostatic repulsion effect. As result, ITO‐decorated anode achieves stable plating/stripping more than 4500 h delivers high average Coulombic efficiency 99.6% after 1400 cycles at 1.0 mA cm −2 . This work provides new horizon rational construction achieve highly reversible dendrite‐free metal anode.

Abstract Aqueous zinc‐ion batteries (AZIBs) are considered one of the most promising next‐generation energy storage devices due to cost‐effectiveness and high safety. However, uncontrolled dendrite growth intolerance against low temperatures hinder application AZIBs. Herein, hydrogen‐bonding‐rich dulcitol (DOL) is introduced into ZnSO 4 , which reshaped hydrogen‐bond network in electrolyte optimized solvation sheath structure, effectively reducing amount active water molecules inhibiting hydrogen evolution parasitic reaction at zinc anode. In addition, higher adsorption DOL preferentially adsorbs on surface anode, guiding uniform deposition Zn 2+ formation dendrites. also enhances interaction between free improves resistance freeze electrolyte. Consequently, Zn//Zn symmetric cells assembled with extremely stable cycled for 2000 h 2 mA cm −2 . The NH V O 10 (NVO)//Zn full cell showed more excellent specific capacity 183.07 mAh g −1 after 800 cycles. Even temperature −10 °C, still maintains 155.95 600 This work provides a new strategy subsequent study AZIBs stability temperatures.

Abstract Electrolyte additives are commonly employed in aqueous zinc‐ion batteries (ZIBs) to suppress dendrite growth, corrosion, and hydrogen evolution. However, rational design principles systematic mechanistic studies for selecting suitable regulate reversible Zn plating/stripping chemistry worth in‐depth study. Using L‐ascorbic acid sodium (LAAS) as the representative, theoretical calculations combined with situ experimental analyses manifest that polyhydroxy‐sodium‐salts preferentially chemisorbed on surface construct H 2 O‐poor interfacial microenvironment, suppressing undesirable water‐related side reactions. Concurrently, ions provide an armor shielding layer electric field guide (002) deposition texture. Specifically, sodium‐salts replace O molecules coordinated shell of hydrated 2+ ions, improving electrochemical stability window (ESW) extend working voltage ZIBs. Therefore, Zn||Zn symmetric cell additive exhibits impressive cumulative capacity 7875 mAh cm −2 at high current density 30 mA . Even when discharge expands 1.8 V, Zn||V 5 full realizes a retention 98.26% over 500 cycles. This work quickens advanced ZIBs by green cheap electrolyte additive, which is expected herald innovative phase research high‐stability batteries.
