An amine-functionalized covalent organic framework with catalytic activity is demonstrated to significantly decrease the oxidation barrier and accelerate the oxidation kinetics of LiCl in a rechargeable Li-Cl2 battery. The developed battery exhibits low overpotential and ultrahigh discharge capacity with good stability in a wide temperature range, as reported by Wei Chen, Shenxiang Zhang et al. in their Research Article (e202315931).
