“…Recently, Li et al exploit the Mg-Al LDH, that is, [(Mg 0.667 Al 0.333 )(OH) 2 (CO 3 ) 0.167 (H 2 O) 0.5 ], as an artificial protective SEI on the surface of the Zn metal anode, which manifests multifunctional integration as an optimal SEI. 78 This Mg-Al LDH is in consonance with the criteria of a superior SEI model, which possesses low electron transference and high ion conductivity. In addition, ideal mechanical strength could effectively improve the stability of the Zn@LDH electrode in aqueous electrolytes, contributing to the inhibition of the H 2 O decomposition reaction in the process of electrochemical cycling.…”

The need for large‐scale electrochemical energy storage devices in the future has spawned several new breeds of batteries in which aqueous zinc ion batteries (AZIBs) have attracted great attention due to their high safety, low cost, and excellent electrochemical performance. In the current research, the dendrite and corrosion caused by aqueous electrolytes are the main problems being studied. However, the research on the zinc metal anode is still in its infancy. We think it really needs to provide clear guidelines about how to reasonably configure the system of AZIBs to realize high‐energy density and long cycle life. Therefore, it is worth analyzing the works on the zinc anode, and several strategies are proposed to improve the stability and cycle life of the battery in recent years. Based on the crystal chemistry and interface chemistry, this review reveals the key factors and essential causes that inhibit dendrite growth and side reactions and puts forward the potential prospects for future work in this direction. It is foreseeable that guiding the construction of AZIBs with high‐energy density and long cycle life in various systems would be quite possible by following this overview as a roadmap.

“…The broadly and densely distributed pores ensure universal and uniform initial nucleation sites on the Zn surface. For some inorganic metal-based compounds, such as nanoporous CaCO 3 [ 56 ], nanoporous SiO 2 [ 56 ], kaolin [ 57 ], Zn-based montmorillonite [ 58 , 59 ], and Mg–Al-layered double hydroxide (LDH) [ 60 ], they are also chemically inert and electronically insulating; therefore, the concentration field redistribution in these modified layers is mainly through their confined channel (Fig. 3 d), thereby inhibiting dendrites, hydrogen evolution, and corrosion.…”

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.

Metal phosphorus trichalcogenides (MPTCs) are structurally adjustable 2D layered materials with unique electronic structures and high chemical diversity, implying the huge potential for energy storage application. In the typical electrochemical reaction process, rapid electron/ion conduction and abundant ion transport channels are the key parameters that influence the overall electrochemical performance of the electrode materials. Herein, 2D Cd 1−x PS 3 Li 2x nanosheets with enhanced mixed electronic/ionic conductivity are synthesized by the intercalation and vacancy strategy. The as-prepared thin-layered Cd 1−x PS 3 Li 2x electrode delivers high capacities of 1056 mAh g −1 at 0.2 A g −1 and 678 mAh g −1 at 8 A g −1 , when used as anode in lithium-ion batteries. The variation of electronic structure and spatial layered structure in Cd 1−x PS 3 Li 2x induced by the synergistic effect of lithium-ion intercalation and Cd vacancies promote the dynamics of mixed electron/ion transport and offer more ion diffusion pathways, resulting in its excellent electrochemical performance. The strategy of mixed electron/ion conduction tuning for Cd 1−x PS 3 Li 2x can be extended to other MPTCs compounds to further develop their potential in the field of energy storage.
