Schematic diagram of the Zn deposition on NC-Nafion@Zn anode. (IMAGE)
Caption
The strategy diagram of NC-Nafion artificial SEI structural design is shown in the Figure. The chemically inert protective layer of Nafion ionomer can serve as a Zn2+ ions conductor, as well as isolate solvent water molecules and shield anions to eliminate side reactions. The evenly decorative high-Fermi-level NC in Nafion accelerates the decoupling process of [Zn(H2O)6]2+ outside the inner Helmholtz plane by reducing the charge density of Zn2+, achieving fast desolvation and charge transfer kinetics.
