3D Conductive Network Supported Monolithic Molybdenum Disulfide Nanosheets for High‐Performance Lithium Storage Applications

Hierarchical 3D graphene nanoribbons/carbon nanotubes–molybdenum disulfide (GR/CNT‐MoS₂) nanocomposites have been facilely and controllably prepared. The GR/CNT matrix, which is prepared by partial unzipping of multiwalled CNTs, possesses good conductive networks by bridging graphene nanoribbons on different CNTs. MoS₂ with monolithic morphologies is anchored on the GR/CNT conductive networks, achieving the formation of hierarchical GR/CNT‐MoS₂ nanocomposites. As a result of the good dispersion of MoS₂, a large specific surface area (238 m² g⁻¹) of GR/CNT‐MoS₂ nanocomposite has been achieved. Excellent electrochemical performance including high specific capacity (1245 mA h g⁻¹) and good cycling stability (90.9% capacity retention after 200 cycles) of the GR/CNT‐MoS₂ nanocomposites is achieved due to the full exposure of the active sites of MoS₂ nanoflakes, and high electron transport ability of the GR/CNT substrate. These novel GR/CNT‐MoS₂ nanocomposites show promising application in lithium ion batteries, and further provide a new way to design and develop new anode materials.
