摘要：Aqueous zinc-ion batteries (AZIBs) are plagued by uncontrollable dendrite growth and detrimental side reactions, primarily stemming from the absence of a rational solid electrolyte interphase to safeguard the zinc anode. However, it remains challenging for a single structural design or interfacial layer to simultaneously tackle these issues. Herein, a hierarchical zincophilic-hydrophobic rectifying interphase was constructed through the combination of electrospinning and ultrasonic spraying techniques. The outer carbon layer exhibits robust hydrophobicity, effectively suppressing side reactions induced by water molecules and alleviating electrode corrosion. Meanwhile, the inner protective interface facilitates rapid charge transfer through the formation of a Zn–Sn alloy layer and offers abundant zincophilic sites, homogenizing the nucleation process. In addition, the Nafion binder incorporated in the coating establishes efficient ion-transport pathways (Zn2+ transference number of 0.75), enabling fast and uniform zinc deposition. Benefiting from the above synergistic effects, the modified zinc anode achieves stable zinc plating/stripping for over 4000 h at 1.0 mA cm-2, and maintains a cycle life of 600 h even under the harsh condition of 10.0 mAh cm-2. More importantly, the C-Sn@Zn||AlxV2O5 full cell delivers a high initial specific capacity of 293.4 mAh·g-1 at 2 A g-1 and remarkable cycling stability with 85.5% capacity retention after 1500 cycles. This artificial interphase with a hydrophobic-zincophilic hierarchical architecture offers a new design paradigm for high-performance zinc anodes and holds broad prospects for practical applications. ? 2026, The Authors.
