Abstract Achieving a highly robust zinc (Zn) metal anode is extremely important for improving the performance of aqueous Zn-ion batteries (AZIBs) advancing “carbon neutrality” society, which hampered by uncontrollable growth Zn dendrite and severe side reactions including hydrogen evolution reaction, corrosion, passivation, etc. Herein, an interlayer containing fluorinated zincophilic covalent organic framework with sulfonic acid groups (COF-S-F) developed on (Zn@COF-S-F) as artificial solid electrolyte interface (SEI). Sulfonic group (− SO 3 H) in COF-S-F can effectively ameliorate desolvation process hydrated ions, three-dimensional channel fluoride (-F) provide interconnected channels favorable transport ions ion-confinement effects, endowing Zn@COF-S-F dendrite-free morphology suppressed reactions. Consequently, symmetric cell stably cycle 1,000 h low average hysteresis voltage (50.5 mV) at current density 1.5 mA cm −2 . Zn@COF-S-F|MnO 2 delivers discharge specific capacity 206.8 mAh g −1 1.2 A after 800 cycles high-capacity retention (87.9%). Enlightening, building SEI metallic surface targeted design has been proved effective strategy to foster practical application high-performance AZIBs.

Zn metal, as one of the most promising anode materials for aqueous batteries, suffers from uncontrollable dendrite growth and water-induced parasitic reactions, which drastically compromise its cycle life Coulombic efficiency (CE). Herein, a nonionic amphipathic additive Tween-20 (TW20) is proposed that bears both zincophilic hydrophobic units. The segment TW20 preferentially adsorbs on anode, while exposed electrolyte side, forming an electrolyte-facing layer shields active water molecules. Moreover, theoretical calculation experimental results reveal can induce preferential (002) plane by adsorbing other facets, enabling dendrite-free anodes. Benefitting these advantages, stability reversibility anodes are substantially improved, reflected stable cycling over 2500 h at 1.0 mA cm
