Abstract
With rapid development of large-scale grid storage system, aqueous Zn batteries with features of superior safety, low cost and high energy density have attracted a growing number of researchers. However, severe corrosion and dendrite growth of Zn anodes have hindered their cycling performance and commercial application. Here, we fabricated an indium-based protective layer on Zn metal surface via a facile ion-exchange route. The insulating indium-based compounds provide necessary potential gradient to induce Zn plate underneath the coating film. Meanwhile, indium and its derivatives can effectively suppress corrosion and regulate Zn plating behavior due to unique physical and chemical properties. The symmetric cells with In-coated Zn anodes maintain stable stripping/plating process over 1400 h. Improved performance of full cells with modified Zn anode paired with α-MnO2 cathode can be achieved. Our work provides a simple and convenient approach to upgrade corrosion-resistant technology of rechargeable aqueous battery systems.
