The construction of artificial solid electrolyte interfaces on zinc anodes is recognized as an effective strategy to mitigate dendrite formation and side reactions; however, existing methods are often complex time-consuming. In this study, we successfully fabricated a highly stable Sn–Al sol protective layer the surface anode using simple spray-coating technique. This significantly enhances electrochemical performance symmetric cells, achieving cycling for over 2500 h at 1 mA cm–2. Zn//Cu half-cells, coating improves charge–discharge efficiency stability, with 500 950 cycles 5 cm–2, respectively. average during reaches 95.7%, in contrast 85.0% bare Zn, indicating improved utilization Zn2+. Additionally, offers enhanced corrosion resistance effectively promotes uniform Zn2+ growth along (101) crystal plane, reducing formation. Overall, approach presents significant potential high-stability modifications anodes, offering novel industrial application zinc-ion batteries.

Abstract The zinc dendrite growth and the parasitic hydrogen evolution reactions (HER) hinder commercialization of batteries. To address this, a hydroxyl‐rich Boehmite coating (HR‐BC) strategy is developed that combines excellent electrical insulation high ion conductivity. hydrophilic hydroxyl groups facilitate bond formation with hydrated ions, accelerating de‐solvation process suppressing HER. Additionally, electrically insulative nature prevents reduction ions within HR‐BC results in preferential Zn deposition underneath it, leading to dendrite‐free “sandwich structure” HR‐BC//Zn deposition//Zn foil. Symmetric cells using HR‐BC‐Zn electrodes obtain an ultralong stable cycling lifetime 1700 h at 5 mA cm −2 , along cumulative plating capacity 4250 mAh . When paired V 2 O cathode, anode demonstrates capacitance retention 90% average Coulombic efficiency (CE) 99.8% after 4000 cycles. Furthermore, when combined heteroatoms‐doped carbon (HDC) HR–BC–Zn//HDC pouch‐type cell exhibits superior performance nearly 100% CE 15000 cycles 3.0 A g −1 This work highlights effectiveness strategies fostering progression long‐lasting zinc‐based energy storage systems.

Uncontrollable dendrite growth and severe parasitic side reactions on Zn electrodes pose formidable challenges for the application of aqueous Zn-ion batteries. Herein, we engineered a biomimetic inorganic–organic protective layer composed alginic acid lithium magnesium silicate to enhance stability reversibility electrode. This not only diminishes free water concentration near surface but also creates negatively charged ion microchannels transport ions modulate solvation structure. Moreover, robust Mg-SiO2 interphase with high Young's modulus strong zincophilicity can be formed between electrode layer, facilitating uniform deposition along Zn(002) planes. Consequently, this allows achieve impressive cycling lifespan 5500 h at 1 mA cm–2/1 mAh cm–2 Coulombic efficiency 99.5% delivers remarkable cyclability up 8000 cycles in Zn||V2O5 full cells.

Abstract Zinc metal is a high‐capacity and cost‐effective anode material for aqueous zinc‐ion batteries, but its development impeded by dendrite growth interfacial side reactions. In this study, unique dipole molecule (DPM) layer constructed on zinc surface via an in situ etching‐growth strategy to regulate the electric field ion distribution. Theoretical calculations experiments confirm that asymmetrical charge distribution within DPM can significantly remodel of Zn surface. The zincophilic accelerates migration ions through ordered channels. Electro‐ionic regulation achieves dendrite‐free deposition reduces formation byproducts. DPM‐Zn symmetrical cells exhibit ultralow voltage hysteresis (≈ 24.2 mV), highly reversible plating/stripping behavior, stable cycling over 1700 h at 1 mA cm −2 . DPM‐Zn||MnO 2 full exhibited higher specific capacity cycle stability than bare anode. This work verifies feasibility electro‐ionic‐field synergistic robust anodes provides new insights into interface design anodes.
