A hybrid host combined with rigid and flexible structural moieties to confine sulfur species physically and chemically is designed and applied for the lithium-sulfur battery. The self-assembled graphene aerogel with nano-MnO2 modified walls serves as the rigid sulfur container while the cross-linked PVP-PVA interpenetrating network acts as the flexible polysulfide trap. The synergic actions enable the hybrid host to present not only good electronic and ionic 3D transfer pathways, but also superior physical and chemical sulfur confinement. Conse...
