Abstract
The discovery of graphene has opened an unexplored area of two-dimensional (2D) layer-structured materials. Since then, there have been five groups of 2D layered materials reported, including Xenes, MXenes, transition metal chalcogenides (TMCs), nitrides, and organic materials. These layered materials exhibit exceptional physical and chemical properties, and offer great opportunities for addressing real challenges. In this chapter, we focus on introducing updated applications of the many 2D materials in lithium-ion batteries (LIBs). Following the introductory section, in the second part we discuss graphene anodes, graphene-based composite anodes, and graphene-based composite cathodes in LIBs. In the third section, we introduce the most recent studies on new anodes using 2D materials beyond graphene in LIBs, including Xenes, MXenes, and TMCs. Finally, we summarize the chapter and provide an outlook on the future research of LIBs.
