Molecular brush: an ion-redistributor to homogenize fast Zn²⁺flux and deposition for calendar-life Zn batteries

Abstract

A surface-grafting strategy of molecular brushes is demonstrated to create a robust ion-regulating interface toward calendar-life Zn anodes with a high Coulombic efficiency of 99.9% and ultralong cyclability over 2500 h at 10 mA cm −2 .
