The construction of robust electrodes with promoted kinetics of sulfur redox reactions and enduring redox chemistry is crucial for developing advanced Li-S batteries. Herein, a hybrid sulfur cathode based on CuBr quantum dots (QDs)-interspersed reduced graphene oxide (rGO) is first developed for energy-dense Li-S batteries. With the combination of theoretical calculations and experimental results, it is certified that the CuBr QDs anchored on the rGO surface could efficiently improve the chemical adsorption and transformation of sulfur-related ...
