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. In the past, researchers have devoted significant efforts to explore various anode materials to achieve SIBs with high energy density. 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. Moreover, these 2D materials facilitated large surface areas and shorter paths for sodium ion adsorption and transportation 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. Finally, the key challenges and future perspectives of SIBs towards enhancing the sodium storage performance of graphene-based electrode materials are discussed. In summary, we believe that this review will shed light on the path towards achieving long-cycling life, low operation cost and safe SIBs with high energy density using 2D anode materials and to be suitably commercialized for large-scale energy storage applications in the future.
由于钠离子电池（SIBs）生产成本低，被认为是锂离子电池（LIBs）用于下一代可持续大规模储能系统的有吸引力的替代品。然而，在充放电循环过程中，由于钠离子半径大且摩尔质量比锂离子高，会产生较大的体积应变，这进一步导致循环稳定性差和可逆容量降低。过去，研究人员投入了大量精力探索各种负极材料以实现高能量密度的钠离子电池。因此，作为一种有前景的钠离子电池负极材料，包括石墨烯及其衍生物和金属氧化物在内的二维（2D）材料因其层状结构以及优异的物理和化学性质而备受关注。将石墨烯和金属氧化物与其他纳米材料加入电极分别显著提高了电导率、反应动力学、容量、倍率性能并适应了大体积变化。此外，这些二维材料分别促进了大表面积和钠离子吸附与传输的较短路径。在这篇综述文章中，将介绍制备技术、结构构型、钠离子存储机制及其电化学性能。随后，将分别深入讨论与二维负极材料（石墨烯、氧化石墨烯（GO）、过渡金属氧化物等）以及其他类石墨烯基本类似物（锗烯、锡烯等）作为负极材料相关的钠离子电池的最新进展。最后，讨论了钠离子电池在提高基于石墨烯的电极材料的钠存储性能方面的关键挑战和未来前景。总之，我们相信这篇综述将为利用二维负极材料实现长循环寿命、低运行成本和安全的高能量密度钠离子电池的道路提供启示，并在未来适用于大规模储能应用的商业化。
