Developing a functional separator is an important strategy to improve the electrochemical performance of Zn anode by suppressing dendrite growth and parasitic side reactions, thus advancing aqueous zinc-ion batteries. Herein, we experimentally realize with gradient-structure based on CeF3 nanoparticles functionalized glass fibers. The experimental theoretical results confirmed that can tailor Zn2+ flux restrain SO42- transport, promoting dense deposition. strong interaction between H2O separates at electrolyte/Zn interface, reactions. Consequently, Zn||Zn this achieves excellent cycling stability 2500 h 1 mA cm-2 mAh 1000 5 cm-2. This design provides distinctive solution for development
