Abstract
Abstract Aqueous zinc‐ion batteries (AZIBs) offer notable advantages in safety and cost‐efficiency, but Zn dendrite growth and unstable interfacial reactions hinder their commercial viability. A crucial factor in addressing these challenges lies in optimizing the separator to regulate ion transport and stabilize electrode interfaces. Herein, we propose a covalent organic framework (COF)‐based separator with quasi‐single‐ion conduction, specifically a Zn 2+ ‐substituted sulfonate COF (COF‐Zn) membrane, designed to tackle these issues. Featuring a high Zn transference number (0.87) and a thin 25 μm profile, the COF‐Zn separator allows for reduced electrolyte usage (20 μL mg −1 ) while effectively minimizing…
