“…In recent years, various strategies have been explored to optimize the anode of zinc-ion batteries, including electrolyte additives, − novel anodes, , alloy anodes, − hydrogel electrolytes, and the anode protective layer. − Among these strategies, the construction of an anode protection layer has attracted much attention due to its simple operation and clear mechanism. In addition to isolating the direct large-area contact between the zinc anode and the electrolyte to reduce metal corrosion, the construction of the protective layer is also conducive to regulating the orderly transport of Zn 2+ to induce uniform deposition of zinc.…”

Aqueous rechargeable zinc-ion batteries have become an ideal solution for the next generation of energy storage systems due to their low cost and high safety. However, the uncontrollable zinc dendrites and harmful side reactions of metal zinc anodes hinder the further development of aqueous zinc-ion batteries. In this work, the artificial fluoride zinc oxide (F-ZnO) interface phase is integrated in situ on the surface of zinc foil. The F-ZnO interface phase significantly inhibits the side reactions on the surface of the zinc electrode by reducing the direct contact between the electrolyte and the surface of the zinc foil. In addition, F-ZnO modified by a small amount of F doping shows enhanced conductivity and electron transport capacity, avoiding the accumulation of high concentration Zn 2+ on the anode surface, and ultimately promoting the efficient nucleation and orderly deposition of a zinc anode. The cycle life of the symmetrical cell based on F-ZnO is as high as 2600 cycles at an area current density of 4 mA cm −2 , which is much better than that of a commercial pure Zn electrode. The modified F-ZnO@Zn anode truly achieves the purpose of prolonging the anode's life.

Aqueous zinc‐based energy storage systems (Zn‐ESSs) with intrinsic safety and good electrochemical performance are promising power suppliers for flexible electronics, whereas unstable zinc anodes especially in flexible Zn‐ESSs pose a challenge. Herein, a self‐assembled robust interfacial layer to achieve stable zinc anodes in non‐flexible and flexible Zn‐ESSs is reported. Specifically, zinc anodes and their slowly‐released Zn2+ simultaneously interact with tannic acid molecules in ethanol–water solutions, triggering the self‐assembly of a tannic acid/Zn2+ complex interfacial layer (CIL) that firmly anchors on the zinc anodes. The CIL containing abundant carboxyl and phenolic hydroxyl functional groups provides rich zincophilic sites to homogenize Zn2+ flux and accelerate Zn2+ desolvation‐deposition, and traps H+/H2O species to prevent them from corroding zinc anodes, thereby stabilizing the zinc deposition interface. Consequently, the CIL@Zn anodes present superior stability with an operation lifetime exceeding 700 h even at 5 mA cm−2 (28 times longer than that of bare zinc anodes) and ultrahigh cumulative plated capacity of ≈1.8 Ah cm−2. The firm anchoring of the CIL enables the CIL@Zn anodes to endure diverse deformations, thus realizing highly flexible CIL@Zn anode‐based Zn‐ESSs. This work provides thinking in designing stable and flexible zinc anodes, promoting the development of flexible zinc‐based energy storage.

Aqueous zinc‐ion batteries (ZIBs) have been regarded as a promising candidate for the next‐generation energy‐storage devices due to their intrinsic safety, low cost, resource abundance, and environmental friendliness. Nevertheless, the commercial applications of ZIBs have been largely plagued by the instability of the Zn anodes. Interfacial engineering arises as a straightforward and effective method to address the instability issues for the development of high‐performance ZIBs. In this review, a comprehensive overview of recent progress and perspective in interfacial engineering techniques to stabilize Zn anodes in ZIBs is presented. With emphasis on the critical issues regarding the instability problems, including Zn dendrites, hydrogen evolution reaction (HER), corrosion and passivation, the major effects and the underlying mechanisms are analyzed, and the corresponding interfacial engineering strategies as well as analytical technologies are summarized. The existing challenges and opportunities in interfacial engineering are also prospected for the future development of high‐performance ZIBs.
