Abstract:

Aqueous zinc-ion batteries utilize environmentally friendly and inherently safe water-based electrolytes, aligning with the demands of large-scale sustainable energy storage, and have garnered widespread attention in recent years. However, their commercialization still faces multiple critical challenges. Among them, the zinc metal anode is prone to a series of side reactions during charge and discharge processes, such as dendrite growth, hydrogen evolution reaction, and corrosion, which severely restrict the battery’s cycling life and Coulombic efficiency. To address these issues, researchers worldwide have proposed various modification strategies focused on optimizing the performance of zinc anodes, primarily in three aspects: structural design, interface modification, and electrolyte regulation. This review systematically summarizes recent advances in zinc anodes. In terms of structural design, it highlights the mechanisms of three-dimensional structured electrodes, alloy electrodes, and epitaxially grown zinc anodes in enhancing specific surface area and nucleation sites. Regarding interface modification, the regulatory mechanisms of functional materials such as carbon-based materials, metal-organic frameworks, and organic polymers on zinc deposition/stripping behavior are discussed. As for electrolyte modification, the critical role of zinc salt structural optimization, electrolyte additive development, and novel electrolyte design in improving the solvation structure and transport behavior of zinc ions is analyzed. Furthermore, by integrating mechanisms such as electrostatic shielding, adsorption effects, desolvation effects, in-situ interface films, and crystal plane regulation, this review systematically outlines the main strategies for optimizing the performance of zinc metal anodes in aqueous zinc-ion batteries. Finally, this discussion is further extended to the dimension of functional separator modification, with an emphasis on the indirect regulatory effects of functional separators on zinc deposition behavior through mechanisms such as homogenizing ion flux, constructing ion-sieving channels, and modulating the interfacial chemical environment. Finally, an outlook for future research directions toward high-performance aqueous zinc-ion batteries is provided.
