Due to their low production cost, sodium‐ion batteries (SIBs) are considered attractive alternatives to lithium‐ion batteries (LIBs) for next generation sustainable and large‐scale energy storage systems. However, during the charge/discharge cycle, a large volume strain is resulted due to the presence of a large radius of sodium ions and high molar compared to lithium ions, which further leads to poor cyclic stability and lower reversible capacity. Hence, as a promising anode material for SIBs, the two‐dimensional (2D) materials including graphene and its derivatives and metal oxides have attracted remarkable attention due to their layered structure and superior physical and chemical properties. The inclusion of graphene and metal oxides with other nanomaterials in electrodes have led to the significant enhancements in electrical conductivity, reaction kinetics, capacity, rate performance and accommodating the large volume change respectively. In this review article, the fabrication techniques, structural configuration, sodium ion storage mechanism and its electrochemical performances will be introduced. Subsequently, an insight into the recent advancements in SIBs associated with 2D anode materials (graphene, graphene oxide (GO), transition metal oxides etc.) and other graphene‐like elementary analogues (germanene, stanine etc.) as anode materials respectively will be discussed.

With a high theoretical capacity, the MnS anode, however, exhibits a rather complex sodium diffusion kinetics and poor mechanical stability that hinder its application in sodium‐ion batteries (SIBs). In this work, a simple, economical, and scalable strategy is developed to inherently coat nanoporous MnS with a 3D N, S co‐doped thin carbon layer by using commercially available MnCO3 as precursors. Specifically, the strategy involves a two‐step annealing process, which converts the MnCO3 microparticles into nanoporous Mn2O3 and MnS step by step. The 3D N, S codoped carbon layer is in situ formed during the second annealing process by first coating the nanoporous Mn2O3 with a polyaniline layer. Due to the inherent 3D carbon protection and the strong electronic interaction between N, S dopants and MnS, the N, S codoped carbon protected MnS obtained at 900 °C (NS‐C@MnS‐900) anode displays a high specific capacity of 845 mAh g−1 at 0.1 A g−1, which is higher than all reported MnS‐based SIB anodes. It also shows an outstanding cyclability and rate performance, maintaining a stable capacity of ≈493 mAh g−1 after 1300 cycles at 10 A g−1, which is also the best according to knowledge. These exceptional electrochemical performances and the scalable/simple/low‐cost synthesis make the NS‐C@MnS‐900 attractive for industry application.
