Ultrathin MoS 2 Nanosheets@Metal Organic Framework‐Derived N‐Doped Carbon Nanowall Arrays as Sodium Ion Battery Anode with Superior Cycling Life and Rate Capability

This study reports the design and fabrication of ultrathin MoS 2 nanosheets@metal organic framework‐derived N‐doped carbon nanowall array hybrids on flexible carbon cloth (CC@CN@MoS 2 ) as a free‐standing anode for high‐performance sodium ion batteries. When evaluated as an anode for sodium ion battery, the as‐fabricated CC@CN@MoS 2 electrode exhibits a high capacity (653.9 mA h g −1 of the second cycle and 619.2 mA h g −1 after 100 cycles at 200 mA g −1 ), excellent rate capability, and long cycling life stability (265 mA h g −1 at 1 A g −1 after 1000 cycles). The excellent electrochemical performance can be attributed to the unique 2D hybrid structures, in which the ultrathin MoS 2 nanosheets with expanded…
