 In recent years, two-dimensional (2D) materials, including graphene and inorganic graphene analogs (IGAs), have been a subject of intensive studies due to their novel chemical and physical properties. With apparent high surface-to-volume ratio, 2D materials are promising electrode candidates for lithium ion batteries (LIBs). Compared with three-dimensional bulk crystals, 2D materials have superior structural characteristics, and thus can exhibit higher specific capacities and better high-rate stabilities. Especially, composites consisting of graphene and IGAs could have enhanced electrochemical performances due to the specific synergic effects, which open up new frontiers in fundamental science and technology. Though the explorations of using IGAs for lithium storage just began, a timely overview in this field is necessary for developing better electrode candidates. In this review, we summarized the on-going efforts and studies from both experimental and theoretical communities on developing graphene and IGAs as LIB electrodes. Compared with graphene, we put more emphasis on IGAs, such as transition metal oxides (TMOs), dichalcogenides (TMDs), and MXene, and illustrate the great advantages of IGAs as electrodes. We also show that due to the high effective synergic interactions between graphene and IGAs, their composites step further to achieve reversible high-capacity LIBs. Finally, we also discuss the problems and barriers for the applications of 2D materials to LIBs.
