Abstract

Carbon-based materials have enabled the fabrication of various energy conversion and storage devices with enhanced performances. In this paper, we review in detail different nanostructured carbon-based materials (such as commercial carbon, carbon nanotube/nanofibre, graphene, porous carbon, functionalised carbon, and composite carbon materials with noble metals and metal oxides) as cathodes for non-aqueous Li-O2 batteries. From a materials point of view, the latest trends (mostly since 2012) in the design of catalysts for non-aqueous Li-O2 batteries are discussed. Finally, a summary and outlook for nanostructured carbon-based materials for non-aqueous Li-O2 batteries are presented, including the challenges that lie ahead.
