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

Abstract Rechargeable aqueous zinc‐ion batteries (ZIBs) with low cost and high safety arouse most promises as next‐generation energy storage configurations. Yet the heterogeneous electric field distributions interfacial side reactions are considered stumbling roadblocks toward commercialization of ZIBs. Here, these challenges via cationic electrostatic shielding anionic preferential adsorption by sodium gluconate (SG) additive addressed. The polar functional groups (─COO − ) SG anions preferentially anchor to Zn anode, which can alter 2+ migration pathways restrain reactions. Moreover, per smaller effective reduction potential, separated cations (Na + from serve a dynamic armor provide strong effect for uniform deposition on [002] crystal plane, radically eliminating dendrite growth promoting anti‐corrosion behaviors Zn. Consequently, Zn//Zn symmetric cell modified electrolyte confers lifespan up 600 h at 80% depth discharge. Furthermore, even under record‐low negative/positive ratio 2.11 lean 30 µL mAh −1 , Zn//VOX full remains enhanced capacity retention 84.37% after 800 cycles 1 A g .
