Inhibiting Interfacial Electron Leakage via An Artificial Rectified Layer for Longevous Zinc Metal Anodes.

Dendrites and water-induced side reactions impose greatly challenge on the implementation of aqueous zinc ion batteries. To tackle these problems, an artificial rectified layer (ARL) with hydrophobic, zincophilic and insulating features was in situ synthesized on Zn surface rapidly to prevent the electron leakage from Zn anode to aqueous electrolyte, which is the underlying logic for uneven Zn deposition and parasitic side reactions. The ARL also displays a high Zn transference number of 0.
