摘要：The sluggish kinetics and poor thermodynamic stability significantly hinder the practical application of zinc (Zn) metal anodes. The artificial zincophilic interface accelerates Zn2+ deposition but induces intense side reactions, whereas the zincophobic one exhibits the opposite effect. Herein, we innovatively construct a gradient zincophobic-zincophilic interface layer on the zinc anode (PDA-PSBMA@Zn) via self-assembly to break the above trade-off. The aromatic rings and alkyl chains accumulating at the electrode-facing side enhance the thermodynamic stability, while the abundant sulfonate groups near the electrolyte-facing side accelerate Zn2+ desolvation, transport, and deposition kinetics, thereby inducing uniform deposition along the (002) plane. Consequently, symmetric cells with PDA-PSBMA@Zn demonstrate stable cycling for 4200 h at a current density of 1 mA cm-2 and 820 h at 20 mA cm-2. Zinc-ion hybrid capacitors assembled with PDA-PSBMA@Zn and activated carbon retain 97.74% capacity retention after 40 000 cycles at 5 A g-1. This work provides a feasible strategy for balancing the kinetic rate and thermodynamic stability of metal anodes in aqueous energy storage devices.
