Abstract
Abstract Aqueous zinc‐ion batteries feature high safety, low cost, and relatively high energy density; however, their cycle life is hindered by severe Zn dendrite formation and water‐induced parasitic reactions. Herein, a porous polyaniline (PANI) interfacial layer is developed on the surface of Zn metal anode to regulate the transport and deposition of Zn 2+ , achieving an ultra‐stable and highly reversible Zn anode. Specifically, the abundant polar groups (NH and N) in PANI have a strong attraction to H 2 O, which can trap and immobilize H 2 O molecules around Zn 2+ . Moreover, the protective layer regulates ion flux and deposition behavior of Zn 2+ through the ion confinement effect. Consequently, the…
