“…Limited energy resources have been a major problem facing the world over the past few decades. Currently, with rapid developments in science and technology, traditional fossil energy is on the verge of exhaustion; as a result, the demand for new energy sources, such as tidal, solar, wind, and nuclear power, has increased [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 ]. However, the direct application of these energy sources in daily life is difficult; thus, it is a better choice to convert them into electricity to power electronic devices [ 10 , 11 , 12 ].…”

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.
