Graphene-like MoS(2) Nanosheets on Carbon Fabrics as High-Performance Binder-free Electrodes for Supercapacitors and Li-Ion Batteries

[Image: see text] Two-dimensional layer-structure materials are now of great interest in energy storage devices, owing to their graphene-like structure and high theoretical capacity. Herein, graphene-like molybdenum disulfide (MoS(2)) nanosheets were uniformly grown on carbon fabrics by using a hydrothermal method. They were evaluated as binder-free electrodes for Li-ion batteries (LIBs) and supercapacitors. As expected, long cycling life and high capacity/capacitance are achieved. When used as self-standing electrodes for LIBs, they deliver a high area capacity of ∼0.5 mAh/cm(2) even after 400 cycles and remarkable rate capability in the charge/discharge potential range of 1–3 V. In addition, a three-dimensional integrated electrode of the MoS(2) nanosheet exhibits a high capacitance of 103.5 mF/cm(2) and long cycling stability up to at least 15 000 cycles at a current density of 3 mA/cm(2) for supercapacitors. The great cycling stability of MoS(2) in supercapacitors is promising in the enhancement of cycling stability through their integration with other materials as alternatives to graphene in some special fields.
