Employing “solid-state” mechanism can avoid polysulfides dissolution in lithium-sulfur batteries but lead to limited reactivity. It is desirable to eliminate polysulfides dissolution under “dissolution-deposition” mechanism but merely impossible with S 8 due to its intrisic parasitic reaction pathway. However, sulfurized polyacrylonitrile ([email protected]) is suggested to involve S 3-4 and.
