“…[1] Nevertheless, Zn anode suffers notorious issues of dendrites growth, hydrogen evolution and surface passivation, which greatly restrict its stability and reliability. [2] It is found that Zn dendrites caused by uneven nucleation inevitably increase the exposed area with electrolyte and accelerate hydrogen corrosion; [3] the local increment of OH À promotes formation of insoluble passivated products; and then the accumulation of insulating byproducts aggravates the non-uniform surface and in turn promotes dendrites growth, inducing poor Zn reversibility and rapid capacity decay. [4] Rational regulation of the Zn-electrolyte interfaces is of vital importance for highly reversible Zn anodes.…”

Zn deposition with a surface‐preferred (002) crystal plane has attracted extensive attention due to its inhibited dendrite growth and side reactions. However, the nucleation and growth of the Zn(002) crystal plane are closely related to the interfacial properties. Herein, oriented growth of Zn(002) crystal plane is realized on Ag‐modified surface that is directly visualized by in situ atomic force microscopy. A solid solution HCP‐Zn (~1.10 at.% solubility of Ag, 30 °C) is formed on the Ag coated Zn foil (Zn@Ag) and possesses the same crystal structure as Zn to reduce its nucleation barrier caused by their lattice mismatch. It merits oriented Zn deposition and corrosion‐resistant surface, and presents long cycling stability in symmetric cells and full cells coupled with V2O5 cathode. This work provides insights into interfacial regulation of Zn anodes for high‐performance aqueous zinc metal batteries.

Zinc metal has emerged as a promising candidate for high‐capacity and low‐cost anodes in aqueous zinc‐ion batteries; nevertheless, it encounters serious obstacles, including low cycling stability and poor reversibility, caused by parasitic reactions and the formation of zinc dendrites. Herein, the study proposes a novel nonprotonic dimethylacetamide (DMAC)/ZnCl2/LiCl electrolyte that enables both solvation structural modulation of [ZnClx]2‐x and the cationic electrostatic shielding effect of [Li(DMAC)]+ by controlling the concentration of LiCl. The optimal concentration of LiCl electrolyte (0.28 m), which results in the highest ratio of [ZnCl3]−, strikes a balance between low desolvation energy and a high mass transfer rate while promoting homoepitaxial deposition of Zn (002). Moreover, inert [Li(DMAC)]+ ions, which possess a lower reduction potential, preferentially adsorb onto zinc protrusions, mitigating the tip effect. Leveraging electrolyte engineering, the zinc deposition/stripping process results in impressive long‐term stability, surpassing 2,800 cycles, and the Zn||MnO2 cell also achieves a stable lifespan extending beyond 1400 cycles. The research highlights the potential of LiCl as an additive in the modulation of water‐free electrolytes.

Rechargeable aqueous Zn metal batteries (RAZMBs) are considered as a competitive alternative to the next generation of energy storage system. However, the Zn stripping/plating reversibility is greatly limited by the dendrite growth and the side reactions on Zn anode. In virtue of the excellent protection and ion migration regulation effects, porous organic polymer artificial solid electrolyte interphases (POPASEIs) have attracted widespread attention in stabilizing Zn anode. This article summarizes the progress of Zn anode POPASEIs in recent years, divided into two categories according to the polymer matrix: porous polymer‐based POPASEIs and nonporous polymer‐based POPASEIs. The porous polymer‐based POPASEIs can be divided into porous coordination organic polymer (PCOOP)‐based and porous covalent organic polymers (PCVOP)‐based ASEIs according to the chemical structure, while nonporous polymer‐based POPASEIs can be divided into four types according to the pore‐forming strategies, including phase separation‐induced POPASEIs, template‐assisted POPASEIs, fiber‐formed POPASEIs, porous filler‐modified POPASEIs. In addition, the structural advantages, challenges, and perspectives of POPASEIs for Zn anode are also discussed to provide guidance for the further research and development of Zn anode ASEIs.
