Directionally Modulated Zinc Deposition by a Robust Zincophilic Cu-Phthalocyanine Protective Layer in Dendrite-Free Aqueous Zinc Ion Batteries.

ABSTRACT: The directional modulation of zinc (Zn) deposition with further investigation of the dendrite-formation mechanism is vital in artificial anode protective layer for aqueous Zn-ion batteries (AZIBs). Herein, a robust metalated covalent organic framework (CuPc-COF) used as the artificial anode protective layer is proposed, in which the zincophilic sites of π-conjugated periodic skeletons are precisely designed to modulate the directional migration of Zn²⁺, the multiple redox-active sites facilitate the Zn²⁺ confinement and transfer, and the central metal copper (Cu) serves as the inhibitor to eliminate the hydrogen evolution side reactions. By combining theoretical calculations with experiments, the π-conjugated planar CuPc-COF layer is a desired protective coating of AZ
