Abstract The zinc (Zn) anode in zinc‐ion batteries suffers from potential defects such as wild dendrite growth, severe Zn corrosion, and violent hydrogen evolution reaction, inducing erratic interfacial charge transfer kinetics, which eventually leads to electrochemical failure. Here, collagen, a biomacromolecule, is added achieve the reconstruction of electrolyte hydrogen‐bonding network modification derived interface. Benefiting electronegativity advantage amino groups (‐NH 2 ) (002) crystal plane preferentially exposed solid interface (SEI) rich ZnF 3 N promotes rapid anode. Thence, an impressive cumulative capacity 7,500 mAh cm −2 at 30 mA achieved assembled Zn|VO cell exhibited robust cycle reversibility even when subject maximum current 100 A g −1 ultra‐long life 20,000 cycles 50 , with single‐cycle loss low 0.0021%. Such convenient strategy solvent sheathing regulation manipulation opening up promising universal approach toward long‐life high‐rate anodes.

Abstract Commercial 3D zinc foam anodes with high deposition space and ion permeation have shown great potential in aqueous batteries. However, the local accumulated stress from its high‐curvature surface exacerbates Zn dendrite issue, leading to poor reversibility. Herein, we employed zincophilic N‐doped carbon @ Sn composites (N‐C@Sn) as nano‐fillings effectively release of curvature foams toward dendrite‐free anode battery (AZIB). These electronegative conductive N‐C@Sn supporters can provide a highly channel for initial nucleation reduce current density regulating deposition. Uniform further assists homogenous distribution on platting surface, which gives positive feedback loop improve As result, composite (ZCSn Foam) symmetric cell achieves long cycle lifespan 1100h at 0.5 mA cm −2 , much more than that Foam (∼80 h lifespan). The full ZCSn Foam||MnO 2 exhibits remarkable reversibility 67% retention after 1000 cycles 0.8 A g −1 76% 1600 Ag . This 3D‐constructing strategy may offer promising practical pathway metal application.

Abstract Aqueous zinc‐ion batteries (AZIBs) have emerged as a promising energy storage solution owing to their intrinsic safety, low cost, environmental friendliness, and high theoretical specific capacity. However, practical application is hindered by uncontrollable dendrite growth side reactions at the zinc metal anode. To address these challenges, simple cost‐effective electrodeposition strategy proposed construct quaternary Zn‐Cu‐Sn‐Bi alloy artificial interface layer on foil (ZCSB@Zn) anode of AZIBs. Density functional theory (DFT) calculations in situ optical observation confirm that this dense reduces migration barrier weakens hydrogen adsorption, facilitating uniform deposition while effectively suppressing formation. The symmetric ZCSB@Zn cell exhibits extraordinary cycle stability exceeding 8000 h. Furthermore, assembled ZCSB@Zn//CSB‐MnO 2 full demonstrates capacity 199 mAh g −1 1 A , maintaining even under loading 10 mg cm −2 temperature conditions (50 °C). This study presents scalable for constructing layers anodes, highlighting potential AZIB applications.

Abstract Protective coatings for Zn anode are developed to suppress dendrite growth, inhibit hydrogen evolution reaction (HER), and provide good anti‐corrosion properties. However, preparing protective with all three of these characteristics remains a challenge. In this study, triple‐functional amorphous 2 O 3 layer anodes is designed. The high redox potential In/In 3+ ensures the stability coating in aqueous electrolytes effectively suppresses HER. Theoretical calculations indicate that In₂O₃ has ⁺ affinity, which lowers nucleation barrier growth. Furthermore, anisotropy material provides homogeneous 2+ adsorption sites enhances corrosion resistance. Consequently, @Zn symmetric batteries have excellent cycle life far exceeding bare Zn, showing ability undergo continuous stripping/plating at 1 mA cm −2 >5400 h. At current density 10 A g −1 , an @Zn//Ca‐V 5 full cell retains specific capacity 307.3 h after 5000 cycles (cycle retention: 76%). successful preparation new approach obtaining highly stable long‐life anodes.
