Rational synthesis of MoS₂ nanosheet arrays on carbon fibres for sodium ion storage

Abstract

Rational synthesis of advanced anode materials is vital in developing high-performance sodium ion batteries. In this work, we report a facile hydrothermal strategy for construction of carbon fibre cloth (CFC) supported MoS₂ nanosheet arrays. Interconnected NoS₂ nanosheets of 5–10 nm are uniformly grown on the surface of CFC forming arrays structure. Good adhesion and high porosity are obtained in the CFC/MoS₂ arrays. When evaluated as anodes of sodium ion batteries, the CFC/NoS₂ arrays deliver a high specific capacity of 413 mAh g⁻¹ at a current density of 0·5 A g⁻¹, and 176 mAh g⁻¹ at a current density of 3 A g⁻¹. Additionally, good rate performance and cycling life are proven for the CFC/MoS₂ arrays. The good performance is ascribed to the CFC network and arrays architecture. Our synthetic method can be used for fabrication of other advanced metal sulfides anodes for sodium ion batteries.

Carbon fibre cloth (CFC) supported MoS₂ arrays electrodes are synthesized via a hydrothermal method and exhibit a noticeable electrochemical performance as anode of sodium ion batteries.
