Abstract Aqueous zinc ion batteries are often adversely affected by the poor stability of metal anodes. Persistent water‐induced side reactions and uncontrolled dendrite growth have seriously damaged long‐term service life aqueous batteries. In this paper, it is reported that a sulfide with optimized electron arrangement on surface anode used to modify achieve cycle anode. The effective active sites first significantly improved simple ultrasound‐assisted etching strategy, then in situ interface phase further guides deposition behavior protective layer well regulates interfacial electric field migration Zn 2+ , thereby promoting homogenization flux dendrite‐free deposition. addition, full cell assembled based ZnS@3D‐Zn achieves better output performance cycles. summary, work sheds light importance reasonable modification for development stable chemistry, which opens up new path zinc‐based

Abstract The rampant “top‐growth” dendrites, hydrogen evolution reaction (HER), and zinc (Zn) self‐corrosion severely impede the further development of rechargeable aqueous ion batteries. To address these challenges, a novel double‐layer gradient coating consisting zincophilic Sn inner layer an organic polymer outer (OSA/PAM@Sn) is constructed on surface Zn anode. layer, composed cross‐linked oxidized sodium alginate polyacrylamide (OSA/PAM), not only serves as physical barrier to isolate active water but also accelerates 2+ diffusion by facilitating desolvation process [Zn(H 2 O) 6 ] due its plentiful polar functional groups, thereby effectively suppressing detrimental HER self‐corrosion. Simultaneously, loose can offer abundant nucleation sites induce uniform “bottom‐to‐top” deposition with low overpotential. Benefiting from synergistic effect designed coating, OSA/PAM@Sn‐Zn anode exhibits remarkable reversibility, lifespans over 5000 1200 h at 1 mA cm −2 –1 mAh 5 –5 in symmetric cells, respectively. Additionally, MnO ||OSA/PAM@Sn‐Zn full battery displays improved rate performance cycle stability. This work emphasizes importance effects interface design achieve side reaction‐free dendrite‐free anodes.

Abstract The formation of dendrites associated with corrosion reactions undermines the cycling stability aqueous zinc‐ion batteries (AZBs). Despite extensive efforts, conventional strategies, e.g., electrolyte modification, and artificial protection layers, often suffer from low stability. Inspired by cell membranes, a series phospholipid analogues C n P m is designed which can spontaneously adsorb onto Zn electrode to form bimolecular protective layer. By tuning head length or tail lipid analogues, nanostructures layer be modified in terms coverage thickness, affecting electrochemical behavior electrode. most optimal found for adsorption 12 2 at concentration 1 mM. bilayer formed denser more stable than those other analogues. facilitated balance plating/striping, thereby effectively limiting growth side reactions, further enhancing reversibility zinc‐based batteries. In symmetric battery experiments, exceed 3600 h under mA cm −2 mAh test conditions. Thus, this study not only demonstrates bio‐friendly material but also provides constructive suggestions on molecular design material.
