• A double-layered protective film based on zinc-based coordination compound and ZnF₂-rich solid electrolyte interphase layer has been successfully fabricated on the zinc metal anode via electrode/electrolyte synergistic optimization.

• The double-layered architecture can effectively modulate Zn²⁺ flux and suppress the zinc dendrite growth, thus facilitating the uniform zinc deposition.

• The as-developed zinc-(dual) halogen batteries based on double-layered protective film can present high areal capacity and satisfactory cycling stability.
