Three-dimensional hierarchical porous TiO2/graphene aerogels as promising anchoring materials for lithium‒sulfur batteries

A three-dimensional TiO2/graphene aerogel (TiO2/GA) composite with hierarchical porous structure, showing strong interfacial chemical and physical interactions with soluble polysulfide intermediates (Li2Sn, 4 ≤ n ≤ 8), is effectively applied as a promising anchoring material for lithium‒sulfur batteries.382
