Fluorine-containing poly(p-phenylene) (CityU-42) films on zinc surfaces were directly synthesized using a cathodic dehalogenation C-C coupling strategy. The as-prepared polymers can effectively protect the substrate in aqueous zinc-ion batteries. Because CityU-42 is rich electronegative fluorine group, it attract uniform deposition and rapid diffusion of Zn2+ surface anode. Moreover, large number benzene rings provide certain mechanical strength, enabling protective layer to inhibit growth dendrites. As result, symmetric Zn cell used CityU-42@Zn stably cycle for over 1,900 h under 5 mA cm-2 1 mAh cm-2, while V2O5 full cells maintain high capacity retention after 800 cycles at A g-1. results highlight potential synthesizing conjugated technology, paving way further advancement field energy storage technology.

Abstract Aqueous battery with nonflammable and instinctive safe properties has received great attention. However, issues related to Zn anode such as side reactions rampant dendrite growth hinder the long‐term circulation of AZMBs. Herein, an ultrathin(35 nm) MoO 3 coating is deposited on by means vacuum vapor deposition for first time. Due peculiar layer structure , insertion 2+ in x acts ion conductor, which regulates ordered manner. Additionally, can also inhibit hydrogen evolution corrosion at interface. Therefore, both Zn//MoO @Cu asymmetric symmetric cells manage deliver satisfactory electrochemical performances. The cell assembled @Zn shows a significant long cycle life more than 1600 h current density 2 mA cm −2 . Meanwhile, @Zn//Cu exhibits ultrahigh deposition/stripping efficiency 99.82% after stable cycling 650 This study proposes concept “zincophile conductor regulation” dictate electrodeposition broadens novel design evaporation nano modified anodes.

One advantage of aqueous zinc-ion batteries (AZIBs) is the utilization zinc metal as an anode. However, long-term stable operation anodes hindered by dendrites and corrosion. Herein, we introduce a Zn–Y–V-oxide-based in situ passive interphase (PI) with crystalline–amorphous hybrid structure that has been optimized for highly reversible Zn anodes. This interface layer enhances corrosion resistance anode electrolyte, reduces side reactions, optimizes electro-crystallization orientation, resulting dendrite-free plating. The modified PI exhibits remarkable stability, sustaining plating/stripping process 2000 h at 1 mA·cm–2 while maintaining high cycling stability good capacity retention when paired NH4V4O10 or α-MnO2 cathodes. Our research presents straightforward one-step reaction fabrication PI, offering approach toward durable long-lasting AZIBs.

Abstract Zn dendrite growth and parasitic reactions at the interface of zinc anode/electrolyte in aqueous batteries severely hinder its lifespan application. Herein, anode is effectively stabilized by introducing trace amounts 4‐aminobutane‐1‐phosphate (ABPA) into ZnSO 4 electrolyte. The ABPA adsorbs onto surface then further decomposes to a high conductive organic/inorganic composite situ SEI layer including amino, partial carbon chain, phosphate. In layer, residual undecomposed chain promotes desolvation 2+ , amino induces uniform plating phosphate facilitates migration . Thus, this not only suppresses water‐related side but also enhances transport kinetics.
