Abstract The feasibility of aqueous zinc‐ion batteries for large‐scale energy storage is hindered by the inherent challenges Zn anode. Drawing inspiration from cellular mechanisms governing metal ion and nutrient transport, erythritol introduced, a zincophilic additive, into ZnSO 4 electrolyte. This innovation stabilizes anode via chelation interactions between polysaccharides 2+ . Experimental tests in conjunction with theoretical calculation results verified that additive can simultaneously regulate solvation structure hydrated reconstruct hydrogen bond network within solution environment. Additionally, molecules preferentially adsorb onto anode, forming dynamic protective layer. These modifications significantly mitigate undesirable side reactions, thus enhancing transport deposition behavior. Consequently, there notable increase cumulative capacity, reaching 6000 mA h cm⁻ 2 at current density 5 cm −2 Specifically, high average coulombic efficiency 99.72% long cycling stability >500 cycles are obtained 1 Furthermore, full comprised MnO cathode an erythritol‐containing electrolyte deliver superior capacity retention. work provides strategy to promote performance anodes toward practical applications.

Abstract The stability of aqueous zinc metal batteries is significantly affected by side reactions and dendrite growth on the anode interface, which primarily originate from water anions. Herein, we introduce a multi H‐bond site additive, 2, 2′‐Sulfonyldiethanol (SDE), into an electrolyte to construct sieving‐type electric double layer (EDL) hydrogen bond interlock in order address these issues. On one hand, SDE replaces H 2 O SO 4 2− anions that are adsorbed surface, expelling O/SO EDL thereby reducing content at interface. other when Zn 2+ de‐solvated interface during plating, strong interaction between can trap EDL, further decreasing their This effectively sieves them out inhibits reactions. Moreover, unique characteristics trapped restrict diffusion, enhancing transference number promoting dendrite‐free deposition Zn. Consequently, utilizing SDE/ZnSO enables excellent cycling Zn//Zn symmetrical cells Zn//MnO full with lifespans exceeding 3500 h 2500 cycles respectively.

Abstract Aqueous zinc‐ion batteries compatible with a wide temperature range and long cycle lifespan show great application prospects but are greatly limited by the unstable electrode‐electrolyte interfaces mismatched electrolytes. This report presents pathway of succinamic acid (SA) additive‐induced built‐in trimodal molecular interaction for constructing sustainable aqueous zinc batteries. As confirmed, such falls into following patterns: binding state H─F bond between SA polyvinylidene fluoride (PVDF) binder, micellar aggregation in electrolyte, spontaneous adsorption at Zn anode–electrolyte interface. Benefiting from above synergistic effect, electrode shows highly reversible deposition/stripping behavior over (−10–50 °C) when paired optimized electrolyte.
