由于其生产成本低,钠离子电池(SIB)被认为是下一代可持续和大规模储能系统的锂离子电池(LIB)的有吸引力的替代品。然而,在充电/放电循环期间,大体积应变是由于存在大半径的钠离子和高摩尔比锂离子,这进一步导致较差的循环稳定性和较低的可逆容量。因此,作为一种有前途的SIBs阳极材料,包括石墨烯及其衍生物和金属氧化物在内的二维(2D)材料由于其层状结构和优异的物理化学性能而备受关注。石墨烯和金属氧化物与其他纳米材料在电极中的掺入导致电导率的显着增强,反应动力学,容量,率性能和容纳大的体积变化。在这篇评论文章中,制造技术,结构配置,介绍了钠离子的储存机理及其电化学性能。随后,深入了解与2D阳极材料相关的SIB的最新进展(石墨烯,氧化石墨烯(GO),过渡金属氧化物等.)和其他类似石墨烯的基本类似物(锗烯,斯坦宁等。)分别作为阳极材料进行讨论。
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.
