Fluorocarbon Surfactant‐Derived Ultrathin Porous Carbon Interface Layer for Stable Zn Anode
Aqueous zinc‐ion batteries are promising for large‐scale energy storage, yet their practical deployment is severely hindered by parasitic hydrogen evolution, dendritic growth, and low Zn utilization. Here, we report an ultrathin (∼5.5 nm) fluorine/oxygen co‐doped porous carbon interface layer constructed on Cu foil...
