Abstract Metallic Zn anodes suffer from hydrogen evolution and dendritic deposition in aqueous electrolytes, resulting low Coulombic efficiency poor cyclic stability for Zn-ion batteries (AZIBs). Constructing stable solid electrolyte interphase (SEI) with strong affinity exclusion of water corrosion metal is a promising strategy to tackle these challenges. In this study, we develop self-healing ZnO-based SEI film on the electrode surface by employing an aspartame (APM) as versatile additive. The hydrophobic nature APM can facilitate dynamic during plating/stripping process. Benefiting superior protection effect SEI, Zn║Cu cells possess average coulombic more than 99.59% over 1,000 cycles even at current density 1 mA cm −2 − mAh . Furthermore, Zn║NH 4 + -V 2 O 5 full display large specific capacity 150 g −1 high retention 77.8% after 1,750 cycles. addition, Zn║Zn cell delivers temperature adaptability wide-temperature range 40 °C under DOD 85.2%. enhanced capability durability originate formation enabled multifunctional additives mediating both suppression interfacial stabilization. This work presents inspired straightforward approach promote dendrite-free rechargeable AZIBs energy storage system.
