Abstract

Functional composite layers composed of an amino-functionalized zirconium 1,4-dicarboxybenzene metal–organic framework were constructed on zinc anodes to mitigate the interface disturbances in aqueous batteries. These layers enable robust Zn²⁺ adsorption and homogenized Zn²⁺ transport and deposition kinetics, facilitating achieving high stability in a symmetric cell (3500 h) and a full cell (35 000 cycles, 96.7%).
