Electrodeposited ZnO/Zn(OH)₂ Nanosheets as a Functional Interface for Dendrite-Free Lithium Metal Anodes.

ABSTRACT: Modifying the current collector is a promising strategy to enable Li metal anodes with minimal Li consumption. Herein, a scalable electrodeposition method is introduced to construct 3D ZnO/Zn(OH)₂ nanosheets on Cu foil (ZOH NSs-Cu foil). Cu(OH)₂ nanowires are first formed via anodization, followed by electroconversion of Cu²⁺ and Zn²⁺ ions. DFT calculations reveal that the ZOH NSs-Cu foil exhibits high Li adsorption energy, imparting strong lithiophilicity and lowering the Li nucleation overpotential. The 3D nanosheet structure provides a large electrochemically active surface, reducing the effective current density. Furthermore, ZOH NSs-Cu foil exhibits low charge transfer resistance and promotes a Li₂O/LiF-rich solid electrolyte inte
