Due to their high safety and low cost, rechargeable aqueous Zn-ion batteries (RAZIBs) have been receiving increased attention and are expected to be the next generation of energy storage systems. However, metal Zn anodes exhibit a limited-service life and inferior reversibility owing to the issues of Zn dendrites and side reactions, which severely hinder the further development of RAZIBs. Researchers have attempted to design high-performance Zn anodes by interfacial engineering, including surface modification and the addition of electrolyte additives, to stabilize Zn anodes. The purpose is to achieve uniform Zn nucleation and flat Zn deposition by regulating the deposition behavior of Zn ions, which effectively improves the cycling stability of the Zn anode. This review comprehensively summarizes the reaction mechanisms of interfacial modification for inhibiting the growth of Zn dendrites and the occurrence of side reactions. In addition, the research progress of interfacial engineering strategies for RAZIBs is summarized and classified. Finally, prospects and suggestions are provided for the design of highly reversible Zn anodes.

“…It reveals the coordination between carbonyl oxygen atoms with Zn 2+ , which can be stronger when polyamide structure collapse over cycling. Molecular layer deposition was employed to produce alucone coating on Zn foil [64] . The nanoscale alucone layer can improve wettability and hence benefit the interface kinetics.…”

As the representative in rechargeable multivalence ion batteries, aqueous zinc ion battery (ZIB) is a promising safe and green solution in the post‐lithium ion era. Though ZIB is being intensively investigated due to its unique merits, the development of ZIB is facing the fundamental obstacles during Zn stripping/plating, namely, zinc dendrite formation, hydrogen evolution, and solid‐electrolyte interface (SEI) formation, which severely affect the cycling stability of ZIB. In this minireview, we aim to provide current aspects of novel approaches to deal with the above critical issues. The approaches are discussed from the perspectives of regulation of electrolyte, construction of Zn anode, and design of surface coating or SEI layer, where their effects on Zn deposition and surface evolution are focused. Last, the challenges and outlooks on the current approaches towards highly reversible Zn anode are presented for the development of ZIB.

“…Secondly, the hybrid films could also be employed as surface coating layers to address liquid-solid and solid-solid interface issues in conventional liquid-based LIBs, solid-state LIBs, and next-generation batteries (e.g., Na, K, and Zn-ion). This surface-engineering approach has been widely demonstrated using alucone, a mature MLD material, in a broad range of applications, such as Si anode (Piper et al, 2014), Li metal (Zhao et al, 2018a), Na metal (Zhao et al, 2017), Zn metal (He and Liu, 2020), Na cathode (Kaliyappan et al, 2020), and many others (Zhao et al, 2021). Compared to insitu formed SEI, the MLD coating, as an artificial SEI on the electrode, become ion and electron conductive upon contact with charge carriers (e.g., Li-ion, Na-ion), possess better mechanical stability and interfacial structure integrity over repeated cycling, and prevent further side reactions between the electrode and electrolyte.…”

“…The incorporation of organic fragments technically opens unlimited possibilities for engineering the structure of metalcone at the molecular level and tailoring their mechanical, electrical, optical, and electrochemical properties for energy storage and conversion systems (Sundberg and Karppinen, 2014;Meng, 2017). For example, MLD alucone has been applied as a flexible surface coating layer on the various anode (Si, SnO 2 , Li/Na/Zn metals) and cathode in rechargeable Li, Na, and Zn batteries (Piper et al, 2014;Zhao et al, 2018a;He and Liu, 2020), and been found to outperform its ALD Al 2 O 3 counterpart in stabilizing the electrode-electrolyte interfaces owing to the added benefits from the organic fragment. For example, alucone coating, deposited by using trimethylaluminum (TMA) and glycerol (GL) at 140°C, was found to improve the cycling stability, rate, and Coulombic efficiency of nano-Si composite electrodes (Piper et al, 2014).…”

The design of multifunctional thin films holds the key to manipulate the surface and interface structure of the electrode and electrolyte in rechargeable batteries and achieve desirable performance for various applications. Molecular layer deposition (MLD) is an emerging thin-film technique with exclusive advantages of depositing hybrid organic-inorganic materials at a nanoscale level and with well tunable and unique properties that conventional thin films might not have. Herein, we provide a timely mini-review on the most recent progress in the surface chemistry and MLD process of novel hybrid organic-inorganic thin films and their applications as the anode, cathode, and solid electrolytes in lithium-ion batteries. Perspectives for future research in designing new MLD process and precursors, enriching MLD material library, and expanding their potential applications in other energy storage systems, are discussed at the end.
