“…The growth of dendrites close to the anode surface is the most severe problem associated with the zinc anode. In the process of charging and discharging, the inhomogeneous deposition of ions worsens the growth of dendrites [ 27 , 28 , 29 ]. Zinc dendrites also have a high Young’s modulus, which makes the membrane inside the battery easy to pierce, thus shortening the cycle life and decreasing the capacity of the battery.…”

Aqueous zinc-ion batteries (AZIBs), the favorite of next-generation energy storage devices, are popular among researchers owing to their environmental friendliness, low cost, and safety. However, AZIBs still face problems of low cathode capacity, fast attenuation, slow ion migration rate, and irregular dendrite growth on anodes. In recent years, many researchers have focused on Zn anode modification to restrain dendrite growth. This review introduces the energy storage mechanism and current challenges of AZIBs, and then some modifying strategies for zinc anodes are elucidated from the perspectives of experiments and theoretical calculations. From the experimental point of view, the modification strategy is mainly to construct a dense artificial interface layer or porous framework on the anode surface, with some research teams directly using zinc alloys as anodes. On the other hand, theoretical research is mainly based on adsorption energy, differential charge density, and molecular dynamics. Finally, this paper summarizes the research progress on AZIBs and puts forward some prospects.

Aqueous Zn‐ion batteries (AZIBs) have attracted much attention due to their excellent safety, cost‐effectiveness, and eco‐friendliness thereby being considered as one of the most promising candidates for large‐scale energy storage. Zn metal anodes with a high gravimetric/volumetric capacity are indispensable for advanced AZIBs. However, pristine Zn metal anodes encounter severe challenges in achieving adequate cycling stability, including dendrite growth, hydrogen evolution reaction, self‐corrosion, and by‐product formation. Because all these reactions are closely related to the electrolyte/Zn interface, the subtle interface engineering is important. Many strategies targeted to the interface engineering have been developed. In this review, a timely update on these strategies and perspectives are summarized, especially focusing on the controllable synthesis of Zn, Zn surface engineering, electrolyte formulation, and separator design. Furthermore, the corresponding internal principles of these strategies are clarified, which is helpful to help seek for new strategies. Finally, the challenges and perspectives for the future development of practical AZIBs are discussed, including the conducting of in advanced in situ testing, unification of battery models, some boundary issues, etc. This review is expected to guide the future development and provi beacon light direction for aqueous zinc ion batteries.

For exploring advanced Zn‐ion batteries (ZIBs) with long lifespan and high Coulombic efficiency (CE), the critically important point is to limit the undesired Zn dendrite and parasitic reactions. Among the coating for electrode is a promising strategy, relying on the trade‐off between its thickness and stability to achieve the ultra‐stable Zn anodes in ZIBs. Herein, a submicron‐thick (≈0.4 µm) zincophilic CrN coatings are fabricated by a facile and industry‐compatible magnetron sputtering approach. It is exhilarating that the ultrathin and dense CrN coatings with strong adsorption ability for Zn2+ exhibit an impressive lifespan up to 3700 h with ≈100% CE at 1 mA cm−2. Along with the experiments and theoretical calculations, it is verified that the introduced CrN coatings cannot only effectively suppress the dendrite growth and notorious parasitic reactions, but also allow the uniform Zn deposition due to the reduced nucleation energy. Moreover, the as‐assembled Zn@CrN‖MnO2 full cell delivers a high specific capacity of 171.1 mAh g−1 after 1000 cycles at 1 A g−1, much better than that of Zn‖MnO2 analog (97.8 mAh g−1). This work provides a facile strategy for scalable fabrication of ultrathin zincophilic coating to push forward the practical applications of ZIBs.
