摘要: 二维(2D)层状材料因有序的层状结构、可调的层间距及丰富的表面化学特性,所以利用其在电化学储能装置(如金属离子电池、锂硫电池、钠硫电池、超级电容器等)中构筑定向离子传输通道的策略成为了当前研究的热点之一。将2D层状材料在电化学储能装置的各个部件(电极、隔膜、固态电解质等)中定向排布,可以构筑低曲折度、长程有序的离子传输通道,实现离子的高速传输,从而有效提升电化学储能装置的充放电性能。本文聚焦电化学储能装置中离子传输过程,全面总结了二维过渡金属碳氮化物(MXenes)、层状双金属氢氧化物(LDHs)、2D层状金属有机框架材料(2D MOFs)、石墨烯及层状黏土矿物等典型2D层状材料在电极、聚合物电解质和隔膜中构筑定向离子传输通道的研究进展,总结了各种2D层状材料定向排布方法(外加电场/磁场/剪切力定向法、自组装法和模板法等)的优缺点。进一步分析了定向离子传输通道结构特性对离子传输性能(离子电导率、离子迁移数、离子扩散系数等)的影响,并深入讨论了2D层状定向离子传输通道中离子传输机理。最后总结了当前研究中所面临的问题和挑战, 并对未来的研究方向进行了展望,以期为开发高性能电化学储能装置提供参考。

Abstract: Two-dimensional (2D) layered materials have attracted extensive attention in the field of electrochemical energy storage due to their ordered layered structure, tunable interlayer spacing, and rich surface chemistry. In particular, the strategy of utilizing their 2D layered structure to construct oriented ion transport channels in electrochemical energy storage devices (e.g., metal-ion batteries, lithium-sulfur batteries, sodium-sulfur batteries, and supercapacitors) has become one of the current research hotspots. By achieving oriented alignment of 2D layered materials in various components of electrochemical energy storage devices (e.g., electrodes, separators, and solid-state electrolytes), long-range ordered ion transport channels with low tortuosity can be constructed, enabling high-speed ion transport and effectively enhancing the charge-discharge performance of these devices. This review focuses on the ion transport processes in electrochemical energy storage devices and provides a comprehensive overview of the research progress in constructing oriented ion transport channels using typical 2D layered materials (e.g., Two-dimensional transition metal carbonitrides (MXenes), layered double hydroxides (LDHs), 2D layered metal-organic frameworks (2D MOFs), graphene, and layered clay minerals) in electrodes, polymer electrolytes, and separators. The advantages and disadvantages of fabrication methods (external electric/magnetic field alignment, shear force alignment, self-assembly, and template methods) for achieving oriented alignment of 2D layered materials are summarized. Furthermore, the influence of the structural characteristics of oriented ion transport channels on ion transport performance including ionic conductivity, cation transference number, and ion diffusion coefficient, is analyzed, and the ion transport mechanisms within 2D layered oriented ion transport channels are discussed in depth. Finally, the current challenges and issues are concluded, and future research directions are proposed, with the aim of providing insights for the development of high-performance electrochemical energy storage devices.
