High specific energy and low cost flexible lithium/sulfur batteries have attracted significantattention as a promising power source to enable future flexible and wearable electronicdevices. Here, we review recent progress in the development of free-standing sulfur compositecathodes, with special emphasis on electrode material selectivity and battery structuraldesign.The mini-review is organized based on the dimensionality of different scaffoldmaterials, namely one-dimensional carbon nanotube (CNT), two-dimensional graphene,and three-dimensional CNT/graphene composite, respectively. Finally, the opportunitiesand perspectives of the future research directions are discussed.
