Abstract Aqueous iron (Fe) metal ion batteries have great application possibilities and prospects due to their remarkably low cost high safety. However, the cycle life of Fe anode is limited by severe corrosion dendrite growth, which hinders practical application. This study employs a double‐layered, two‐dimensional (2D) ordered polyaniline film as protective layer for anodes. On one hand, it forms uniform double‐layer electrostatic field on surface anode, beneficial migration, desolvation, even deposition 2+ suppresses uneven pitting metal. other serves physical barrier prevent corrosive ions water from coming into contact with anode. The enhances symmetric cells cycling over 1600 h at 0.125 mA cm −2 mAh . strategy introducing conductive polymers protection in aqueous metal‐ion will further promote development high‐performance batteries.
