Microwave-assisted synthesis of a ternary MoS2/carbon-FeOx composites with 3D hierarchical nanostructure for lithium-ion battery application.

Three-dimensional (3D) carbon matrix composites have been widely used in the field of lithium-ion batteries due to their unique structure and properties. In this work, we employ a rapid method to synthesize a ternary composite (MoS₂/carbon-FeO_x) with a 3D hierarchical nanostructure via hydrothermal and microwave irradiation treatment. The 3D hierarchical nanostructure is composed of 0D nanoparticles (ultra-small iron oxide), 1D carbon nanotubes, and 2D nanosheets (MoS₂ nanoflowers and graphene), providing extraordinary mechanical and electrochemical stability during the lithiation/delithiation process. As expected, when employed as an anode material, the 3D hierarchical nanostructure delivered a high reversible capacity of 740 mAh g^–1 without any fading tendency after 100 cycles at a current density of 0.2 A·g^–1, and retained over 508 mAh g^–1 even surveyed by a high current density of 2 A g^–1.
