Abstract Zn interfacial issues involved dendrite evolution and undesired parasitic reactions are tough challenges to impede the progress of ion battery. Herein, dendrite‐free anode with boosted stability is achieved by four‐in‐one functional additive triethyl phosphate (TEP). Experiments theoretical calculation reveal that TEP participates in generation compact inorganic interface prevent from corrosion. Meanwhile, electrical double layer (EDL) reconstructed adsorbed molecules inner weakened 2+ solvation structure diffusion layer, which efficiently shields active H 2 O moderate electrochemical kinetics, thereby preventing water‐related secondary reaction electroplating on tip region. Additionally, manipulates zinc growth direction adsorbing (002) facet, thus enabling long‐lasting deposition. Accordingly, Zn||Zn symmetric cell demonstrates an ultralong lifespan over 5000 h (almost 7 months) at 1 mA cm −2 , mAh remarkable coulombic efficiency (CE) ≈97.6% for 1500 cycles. For practical demonstration, Zn||LiFePO 4 full improved rate capability elevated capacity 116.0 g −1 . These findings highlight chemistry manipulated multifunctional additives as efficient approach stabilize anode, holding promise top‐notch Zn‐based batteries longevity.

Abstract Aqueous zinc‐ion batteries (AZIBs) attract attention due to their safety and high specific capacity. However, practical applications are constrained by Zn anode corrosion, dendritic growth, poor temperature adaptability induced a strong hydrogen‐bond network in aqueous electrolytes. Herein, universal strategy design solvating electrolytes is proposed, which the solvation structures reconstructed regulating dipolar‐dipolar ion‐dipolar interactions simultaneously. Consequently, free water largely weakened, content 2+ solvated sheath reduced, while between solvents strengthened, effectively broadens operating range suppresses dendrites corrosion. As result, anodes exhibit excellent platting/stripping efficiency with an average Coulombic Efficiency up 99.89% after 2000 cycles at 0.5 mA cm −2 , impressive cycling stability (5000 h, /0.5 h ), wide of 140 °C (−50–90 °C). Moreover, Zn//V 2 O 3 full cells also display enhanced temperature‐resistance, implying that designed electrolyte has application potential extreme environments. This study suggests promising ideal for high‐performance AZIBs safety, ultralong life, satisfying temperature‐resistance.

Abstract Aqueous zinc ion batteries are gaining popularity due to their high energy density and environmental friendliness. However, random deposition of ions on the anode sluggish migration interface would lead growth dendrites poor cycling performance.
