Precise Regulation of Intra‐Nanopore Charge Microenvironment in Covalent Organic Frameworks for Efficient Monovalent Cation Transport

at 160 °C, surpassing most COF-based ionic conductors. This COF platform for efficient ion migration and stable battery cycling in lithium-metal quasi-solid-state batteries has also been verified as proof of concept. This work offers new insights into the development and structure-activity relationship studies of the next generation of solid-state ionic conductors.
