A stable fluoride-based interphase for a long cycle Zn metal anode in an aqueous zinc ion battery

CaF 2 , which served as the F-rich artificial interphase on the Zn anode was prepared by the spin-coating method. The CaF 2 layer can effectively adjust the uniform deposition of Zn and inhibit the corrosion and side reactions between the electrode surface and electrolyte.
