Abstract
- Heterogeneous interfaces interaction and multiscale nanostructures in two-dimensional (2D) materials hybrids are critically significant for realizing rate capability and long-life cycling performance. However, to strike a balance between minimizing the carbon content and maximizing the heterogeneous interfaces remains a critical challenge in nanoarchitectures for hybrid few-layers MoS<subscript>2</subscript> with various carbonaceous materials. Here we present the ordered macroporous few-layered MoS<subscript>2</subscript>/C hybrid nanoarchitectures via a facile scalable in situ hybridization and spatial confinement strategies. Such hybrid strategies can maximize the MoS<subscript>2</subscript> loading and restriction of MoS<subscript>2</subscript> to a ultrasmall reaction. The optimized as-prepared hierarchical MoS<subscript>2</subscript>/C hybrids exhibit an initial capacity up to 631.2 mAh g<superscript>−1</superscript> with a high first columbic efficiency of 81.16% for sodium-ion batteries (BILs) at 200 mA g<superscript>−1</superscript>. And, the electrodes display a high reversible capacity of 330.4 mAh g<superscript>−1</superscript> with a long cycle life, superior cycling stability and excellent high-rate performance demonstrated rational designed hybrid architecture using as the electrodes in SIBs. This strategy could be proven to be an effective method for stabilizing the cyclability and improving in rechargeable rate performance for SIBs. [ABSTRACT FROM AUTHOR]
