Tailoring the Electrical Double Layer and Interfacial Electric Field with Diverse Configurational Entropy-Driven Electrolyte for Ultrastable Zinc Metal Anodes

The interfacial stability of zinc anodes depends primarily upon the electrical double layer (EDL) environment and interfacial electric field (IEF) in repeated Zn plating/stripping processes. Herein, a high-entropy electrolyte (HEE) with over 68 types of Zn2+ solvation configurations is proposed to modulate the EDL and IEF of Zn anode/electrolyte interface, achieving the improved electrochemical stability and low freezing point. The formation of multiple and water-poor Zn2+ solvation configurations facilitates the ion transport dynamics and the desolvation process in the inner Helmholtz plane (IHP), inducing the formation of an organic–inorganic hybrid solid electrolyte interphase (SEI) layer and…
