Zn-thiocatecholate functionalized MOF modified separator stabilizing zinc anodes for long-life aqueous zinc-ion batteries†
Abstract
A separator (UiO-dcbdt-Zn@GF) modified by Zn-thiocatecholate functionalized MOF is proposed. Benefiting from the unique [S−–Zn–S−] zincophilic moieties, UiO-dcbdt-Zn@GF ensures a uniform distribution of zinc ion flux, enhances ion migration kinetics and assists in the desolvation of hydrated zinc ions, thereby promoting the reversibility of Zn anode in Zn ion batteries.
