Abstract Electrolyte additives are investigated to resolve dendrite growth, hydrogen evolution reaction, and corrosion of Zn metal. In particular, the electrostatic shielding cationic strategy is considered an effective method regulate deposition morphology. However, it very difficult for such a simple modification avoid competitive reactions, corrosion, interfacial pH fluctuations. Herein, multifunctional potassium phthalate (KHP) based on synergistic design anionic chemistry ultrastable Zn||I 2 full batteries demonstrated. K cations, acting as constructed smooth HP anions can enter first solvation shell 2+ reduced activities H O, while they remain in primary finally involved formation SEI, thus accelerating charge transfer kinetics. Furthermore, by situ monitoring near‐surface electrode, KHP effectively inhibit accumulation OH − by‐products. Consequently, symmetric cells achieve high stripping–plating reversibility over 4500 2600 h at 1.0 5 mA cm −2 , respectively. The deliver ultralong term stability 1400 cycles with high‐capacity retention 78.5%.

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.
