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 Interfacial stress caused by semi‐coherent and incoherent interfaces during zinc (Zn) plating its effect on subsequent Zn deposition are important considerations for designing electrode/electrolyte to improve the electrochemical performance of anodes. Although some studies have paid attention this issue, influence lattice strain induced ion diffusion in interface coating is infrequently discussed. Herein, a tin‐doped indium oxide (ITO) interfacial constructed, evolution oxygen vacancy (O V ) generated migration confirmed. The formed O ‐rich ITO exhibits strong affinity low barrier, accelerating transport kinetics. Meanwhile, layer can appropriately capture anions electrolyte corrosion resistance electrode through electrostatic repulsion effect. As result, ITO‐decorated anode achieves stable plating/stripping more than 4500 h delivers high average Coulombic efficiency 99.6% after 1400 cycles at 1.0 mA cm −2 . This work provides new horizon rational construction achieve highly reversible dendrite‐free metal anode.

Abstract Aqueous zinc ion batteries (AZIBs) have garnered significant attention due to their advantages, including high safety, a straightforward manufacturing process, abundant resource availability, and theoretical capacity. Nevertheless, the industrial application of AZIBs is impeded by undesirable growth dendrites side reactions on Zn anode. In this study, [3‐(trimethoxysilyl) propyl] urea (3TMS) utilized as an electrolyte additive develop solid/electrolyte interphase (SEI) film surface The in situ formed SEI layer not only prevents form direct contact anode with water but also induces preferential deposition along (002) crystal plane, suppressing dendrite growth. These synergistic functions enable ultralong cycle life over 6000 h at current density 1 mA cm −2 areal capacity mAh , well coulombic efficiency 99.34% after 750 cycles. Moreover, Zn//V 2 O 5 full cells 3TMS display specific 114.4 g −1 0.5 A 1000 This work provides simple yet feasible approach stable toward high‐performance AZIBs.

Abstract Ag–Zn batteries have the advantages of being a high‐safety and stable discharge platform but still face challenges such as high cost, electrolyte hydrolysis, zinc dendrites. In this study, low‐cost roughness graphite paper (GP) enables more uniform loaded Ag particles to construct Ag/rough (Ag/RGP) cathode with wettability low‐concentration ZnCl 2 electrolyte, achieving both capacity reversibility enhancement. Both few additions citric acid (CA) can also inhibit hydrolysis Zn 2+ increase nucleation overpotential due suitable acidity complexation ability, resulting in even deposited behavior on foil anode. Meanwhile, ‐CA promote redox reaction thus improve Ag/RGP cathode. As result, assembled large‐size battery (50 cm ) obtains 0.76 mAh −2 at current density 0.4 mA , cycle life ≈100% retention over 50 cycles, easily powering LED array displaying practicability. This work provides feasible practical route fabricate batteries.
