Lithium-sulfur battery(Li-S) is rechargeable battery with lightweight and high specific energy. During discharging, polysulfides(S8) reduced on cathode surface which finally goes to Li2S, whose reverse reaction goes to yield S8 on cathode while charging. Desirable separator could exchange Li ions only with while polysulfides remain on cathode electrolyte. Thick graphene film that has co-continuous nano-channels made by block copolymer self-assembly and chemical vapour deposition(CVD) for separator.
