“…The Zn affinity is evaluated by comparing the binding energy (calculated by density functional theory) of the Zn atoms attached to the modified layer and the Zn metal surface, and the larger one (more negative) has a higher Zn affinity [86]. It is reported that some metals have high Zn affinity, such as Sn, In, Ag, and Cu; they can serve as heterogeneous seeds to induce Zn nucleation and growth [87][88][89][90]. Compared with Zn metal or carbon, a wellorganized Sn layer has a uniform and densely distributed zincophilic sites on the surface [87].…”

“…Zn can be fused with various elements to form Zn-based alloys, classified into binary alloys, ternary alloys, and multi-element alloys according to the number of their components. In addition to Ga–In–Zn [ 116 , 117 ] and Zn–Sn–Pb [ 118 ] alloys, the Zn alloys currently reported on mild aqueous Zn anodes are mainly binary alloys, such as Cu–Zn [ 89 , 119 , 120 ], Ag–Zn [ 89 , 121 – 123 ], Zn–Al [ 124 ], Zn–Mn [ 125 ], Zn–Sb [ 115 ], and Zn-P [ 69 ]. The interaction between alloy components will form an alloy phase with a specific structure and composition, which can be divided into solid solution and intermetallic compound [ 126 ].…”

“…This indicates that after Zn is reduced, it will spontaneously form an alloy phase with Ag lattice through solid solution reaction, rather than accumulating at sites containing only Zn species (Fig. 13 d) [ 89 , 121 , 122 ]. However, excessive Zn deposition will still form a Zn layer on the alloy surface, inducing dendrite growth.…”

The rapid advance of mild aqueous zinc-ion batteries (ZIBs) is driving the development of the energy storage system market. But the thorny issues of Zn anodes, mainly including dendrite growth, hydrogen evolution, and corrosion, severely reduce the performance of ZIBs. To commercialize ZIBs, researchers must overcome formidable challenges. Research about mild aqueous ZIBs is still developing. Various technical and scientific obstacles to designing Zn anodes with high stripping efficiency and long cycling life have not been resolved. Moreover, the performance of Zn anodes is a complex scientific issue determined by various parameters, most of which are often ignored, failing to achieve the maximum performance of the cell. This review proposes a comprehensive overview of existing Zn anode issues and the corresponding strategies, frontiers, and development trends to deeply comprehend the essence and inner connection of degradation mechanism and performance. First, the formation mechanism of dendrite growth, hydrogen evolution, corrosion, and their influence on the anode are analyzed. Furthermore, various strategies for constructing stable Zn anodes are summarized and discussed in detail from multiple perspectives. These strategies are mainly divided into interface modification, structural anode, alloying anode, intercalation anode, liquid electrolyte, non-liquid electrolyte, separator design, and other strategies. Finally, research directions and prospects are put forward for Zn anodes. This contribution highlights the latest developments and provides new insights into the advanced Zn anode for future research.

“…To address this issue, various methods have been developed, such as optimizing the electrolytes [17], stabilizing the structure by employing host materials [18], and modifying the surface [19][20][21][22][23][24]. Among surface modification methods, an efficient strategy to stabilize the Zn anode during the stripping/plating process is a surface coating with a metal such as In [19], Au [20], Ag [21], and Cu [21] coating, which acts as a nucleation site to guide uniform Zn deposition. For instance, Zhang et al developed Ag and Cu coatings on Zn metal through the thermal evaporation method [21].…”

Rechargeable aqueous Zn-ion batteries (ZIBs) have gained great attention due to their high safety and the natural abundance of Zn. Unfortunately, the Zn metal anode suffers from dendrite growth due to nonuniform deposition during the plating/stripping process, leading to a sudden failure of the batteries. Herein, Cu coated Zn (Cu–Zn) was prepared by a facile pretreatment method using CuSO4 aqueous solution. The Cu coating transformed into an alloy interfacial layer with a high affinity for Zn, which acted as a nucleation site to guide the uniform Zn nucleation and plating. As a result, Cu–Zn demonstrated a cycling life of up to 1600 h in the symmetric cells and endowed a stable cycling performance with a capacity of 207 mAh g−1 even after 1000 cycles in the full cells coupled with a V2O5-based cathode. This work provides a simple and effective strategy to enable uniform Zn deposition for improved ZIBs.

Dendrite growth and parasitic side reactions are thorny issues that seriously damage the anode-electrolyte interface during Zn plating/stripping process, leading to uncontrollable Zn deposition and restraining application of aqueous Zn-ion batteries (AZIBs). Here, a unique facile strategy to in situ build indium (In) metal interphase on the Zn anode is first proposed. The combination of experimental and theoretical investigations demonstrate that such metallic interphase prevents the hydrogen evolution reaction (HER) and Zn corrosion, and guides preferential growth along the Zn(002) plane to achieve smooth Zn deposition. As a result, the modified Zn anodes achieve the ultrahigh cumulative capacities of 5600 and 5000 mAh cm −2 at the high current densities of 2 and 5 mA cm −2 , respectively, demonstrating an ultrastable plating/stripping behavior. More encouragingly, the rate performance and cyclic stability of the Zn-V 2 O 5 battery with the electrolyte additive can still deliver a specific capacity of 383.6 mAh g −1 after 5000 cycles at the high current density of 5 A g −1 . The strategy presented here as well as the in-depth understanding of modified mechanism can not only provide an effective solution to address the Zn anode concerns, but also deepen the understanding of AZIBs.
