Cationic covalent-organic framework for sulfur storage with high-performance in lithium-sulfur batteries
Journal of Colloid and Interface Science（2021）
Abstract
•The cationic COF-NI has been employed as sulfur storage materials.•The quaternary ammonium salt group was grafted onto the pore channel of COFs.•The shuttle effect of polysulfides was suppressed by employing cationic COF-NI.
