Abstract The incomplete conversion of sulfur species, particularly the pivotal intermediate solid Li 2 S 2 during redox processes, poses a significant limitation on the cyclability of lithium–sulfur batteries (LSBs). Herein, a synergistic modulation strategy of ion‐/dipole–dipole interactions that tailors the solvation sheath configuration and activates the electrochemical reactivity of Li 2 S 2 is initially proposed for accelerating kinetics. As a proof of concept, the molybdenum nitride quantum dots located on n…
