Lithium-sulfur (Li-S) batteries afford great promise on achieving practical high energy density beyond lithium-ion batteries. Lean-electrolyte conditions constitute the prerequisite for high-energy-density Li-S but inevitably deteriorates battery performances, especially sulfur cathode kinetics.

Lithium-sulfur (Li-S) batteries are regarded as promising high-energy-density energy storage devices. However, the cycling stability of Li-S is restricted by parasitic reactions between Li metal anodes and soluble lithium polysulfides (LiPSs).
