在纳米尺度通道内的离子传输是纳米流体学领域研究的重点.二维(2D)材料的本征层状结构为流体离子提供了稳健的纳米传输通道.为实现流体离子在2D材料薄膜内的高效传输,本文开发了一种新颖的异价离子取代插层策略,通过化学气相输运法直接合成多种具有高离子电导结构的单晶.将块体单晶置入水中通过手动摇晃即可获得二维纳米片分散液,组装后的薄膜展现出高的锂离子电导率,优于目前多数关于2D材料薄膜水相锂离子电导率的报道.这种在合成过程中直接构筑离子传输结构的策略与目前已有的先剥离2D材料后对纳米片修饰改性的方法完全不同.因此,这种普适性的异价离子取代插层策略将会为更多高离子电导率的2D材料薄膜的开发提供借鉴与参考.

Commercial application of lithium-sulfur(Li-S) batteries is hindered by the insulating nature of sulfur and the dissolution of polysulfides. Here, a bioinspired 3D urchin-like N-doped Murray's carbon nanostructure(N-MCN) with interconnected micro-meso-macroporous structure and a polydopamine protection shell has been designed as an effective sulfur host for high-performance Li-S batteries. The advanced 3D hierarchically porous framework with the characteristics of the generalized Murray's law largely improves electrolyte diffusion, facilitates electrons/ions transfer and provides strong chemisorption for active species, leading to the synergistic structural and chemical confinement of polysulfides. As a result,the obtained P@S/N-MCN electrode with high areal sulfur loading demonstrates high capacity at high current densities after long cycles. This work reveals that following the generalized Murray's law is feasible to design high-performance sulfur cathode materials for potentially practical Li-S battery applications.
