“…Metal–organic frameworks (MOFs) possess porous structures and rich functional groups, which can be considered as hopeful interface materials to modify Zn anode . Zeolitic imidazolate frameworks (ZIFs) as a category of MOFs have been explored and applied in several research fields in the past few years, such as catalysis, gas separation, and energy storage, and so on. − Common ZIFs are made up of metal sites (e.g., Zn 2+ and Co 2+ ) and imidazole organic ligands with zeolite structure, thereby the strong chelation between N and metal ion ensuring its absorption of metal ions. , Meanwhile, ZIFs directly provide a 3D network, which is conducive to the orderly embedding of other materials such as Zn and Li. − From a catalytic view, ZIFs show effective catalytic activities due to the special Lewis acid (neighboring metal ions) and base (N in imidazole) sites. − Moreover, it has been proved that pure ZIFs possess a negligible capacity for hydrogen evolution in the field of photocatalytic hydrogen evolution . Among many types of ZIFs, a novel two-dimensional (2D) zeolitic imidazolate framework (ZIF-L) showing leaflike shape has attracted the attention of scientists, due to its greater number of active sites and higher specific area surface compared to other shapes of ZIFs. , Generally, most organic ligands are insoluble in water, and only limited MOFs can be obtained in the aqueous systems.…”

The hydrogen evolution and dendrite of Zn anode are the major troubles hindering the commercialization of aqueous Zn-ion batteries (AZIBs). ZIF-Ls, a typical metal−organic framework (MOF) with a highly ordered structure and abundant functional groups, seem to be the answer for the above bottlenecks. In this paper, a uniform ZIF-L layer was obtained on the Zn surface (Zn@ZIF-L) via an in situ synthesis method to moderate the solvation structure of solid−liquid interface electrolyte reducing the contact between water and Zn, thereby relieving the hydrogen evolution and corrosion. Furthermore, density functional theory (DFT) analysis reveals the binding energy of H (−4.01 eV) and Zn (−0.82 eV) for ZIF-L is superior to that of pure Zn (H (−1.49 eV) and Zn (−0.68 eV)). Due to the multifunctional ZIF-L layer, the Zn@ZIF-L can regulate Zn deposition to overcome the dendrite for obtaining a long-life Zn anode. Consequently, the modified Zn@ZIF-L anode can cycle for 800 h at 0.25 mA cm −2 for 0.25 mAh cm −2 , while the bare Zn anode is only maintained for 422 h. Finally, a designed V 2 O 5 grown on carbon cloth (V 2 O 5 @CC

Aqueous Zn‐ion batteries (AZIBs) have attracted lots of attention due to good eco‐friendly, safety and high energy density. However, the dendritic growth and side reactions on Zn anodes have affected the safety and stability of AZIBs. In this paper, an artificial interface protective layer on the Zn anode has been fabricated by a convenient and straightforward replacement reaction of Bi(CF3SO3)3 with Zn anode in dimethoxyethane (DME) solution at room temperature. The Ar+ etching X‐ray photoelectron spectrometer (XPS) proves that the protective layer is composed of metal Bi, ZnS and ZnSO3, suggesting the success of replacement reaction. This artificial protective layer is propitious to control nucleation sites of Zn2+ and favorable Maxwell‐Wagner polarization, resulting in uniform Zn stripping/plating. In addition, the scanning electron microscope (SEM), Tafel plots and X‐ray diffraction (XRD) demonstrate that the interface layer can effectively suppress side reactions and dendrite growth. Therefore, the symmetric cells with modified Zn anode exhibit superior cycling stability at diverse current densities with a fixed capacity of 1 mAh cm−2 and higher coulombic efficiency (CE) than half‐cells with pristine Zn anode. Simultaneously, modified Zn/NH4V4O10 full‐cells present higher specific capacity, superior cycling stability and rate capability. This simple method provides a new way to modify the Zn anodes for the development of industrialization of aqueous rechargeable ZIBs.

Aqueous zinc metal batteries (AZMBs) have emerged as a focal point of interest in academic research and industrial strategic planning. Zinc powder (ZP) is poised to assume a prominent position in both future research and practical applications due to its high Zn utilization rate and processability. However, critical challenges need to be addressed before realizing substantial progress. Notably, severe voltage polarization and gas production of ZP electrodes stand out as the primary causes of battery failure, differing with zinc foil where short circuits caused by zinc dendrites contribute to battery failure. While numerous comprehensive reviews have offered effective strategies for zinc foil, a systematic summary of ZP electrodes is still lacking. For ZP, electrode preparation dictates the performance. This review summarizes the criteria for optimal ZP electrodes, covering electrode components, preparation methods, and technique parameters. It emphatically introduces the underlying causes and strategies of water‐related side reactions and briefly analyzes the stripping/plating behaviors of ZP electrodes. The status quo of ZP‐based batteries is then discussed in categories of ZP, current collector, conductive scaffold, binder, and electrolytes. Finally, potential avenues for future research are proposed from three aspects to enhance the focus on ZP electrodes and facilitate the practical application of AZMBs.
