Research Progress on Energy Storage and Anode Protection of Aqueous Zinc‐Ion Battery

With the advantages of high energy density, abundant resources and environmental friendliness, Aqueous Zinc‐ion Batteries (AZIBs) are considered as one of the promising new energy systems. However, its practical application is limited by the problems of irregular dendrite growth and interfacial side reaction in zinc anode. In view of the above problems, relevant researchers have given solutions such as the construction of artificial protective layer and the regulation of substrate structure. This paper summarizes the relevant literatures in order to help the future research of zinc‐ion batteries. In this paper, the current problems of aqueous zinc ion batteries are introduced, and the deposition mechanism of zinc anode is briefly analyzed; Aiming at the concept of zinc anode protection, the current research are reviewed from two aspects: the construction of anode protection layer and the anode substrate control.
