Synthesis of hierarchical MoS 2 microspheres composed of nanosheets assembled via facile hydrothermal method as anode material for lithium-ion batteries

A hierarchical MoS 2 architecture composed of nanosheet-assembled microspheres with an expanded interplanar spacing of the (002) planes was successfully prepared via a simple hydrothermal reaction. Electron microscopy studies revealed formation of the MoS 2 microspheres with an average diameter of 2... Full description

description: A hierarchical MoS 2 architecture composed of nanosheet-assembled microspheres with an expanded interplanar spacing of the (002) planes was successfully prepared via a simple hydrothermal reaction. Electron microscopy studies revealed formation of the MoS 2 microspheres with an average diameter of 230 nm. It was shown that the hierarchical structure of MoS 2 microspheres possesses both the merits of nanometer-sized building blocks and micrometer-sized assemblies, which offer high surface area for fast kinetics and buffers the volume expansion during lithium insertion/deinsertion, respectively. The micrometer-sized assemblies were found to contribute to the enhanced electrochemical stabilities of the electrode materials. The mentioned advantages of the MoS 2 electrode prepared in this work allowed enhanced cyclability and high rate capability of the material. Along with this, the material delivered a high initial discharge capacity of 1206 mAh g −1 and a reversible discharge capacity of 653 mAh g −1 after 100 cycles at a current density of 100 mA g −1 . Furthermore, the material delivered a high reversible capacity of 480 mAh g −1 at a high current density of 1000 mA g −1 .
