Aqueous rechargeable Zn batteries have been studied as promising energy storage devices because of their low cost, high safety, and environmental friendliness. However, due to the problems faced by Zn anodes, such as dendrites and parasitic reactions (hydrogen evolution reaction and corrosion), commercialization still has a long way to go. In this perspective, a discussion of Zn anodes' current challenges is presented. Starting from this overview Zn anode modification strategies are discussed, which include surface modification, structure optimization, and electrolyte modification. Finally, prospects of future research on Zn anode are outlined.
