Hybrid Structures of Sisal Fiber Derived Interconnected Carbon Nanosheets/MoS(2)/Polyaniline as Advanced Electrode Materials in Lithium-Ion Batteries

In this work, we designed and successfully synthesized an interconnected carbon nanosheet/MoS(2)/polyaniline hybrid (ICN/MoS(2)/PANI) by combining the hydrothermal method and in situ chemical oxidative polymerization. The as-synthesized ICNs/MoS(2)/PANI hybrid showed a “caramel treat-like” architecture in which the sisal fiber derived ICNs were used as hosts to grow “follower-like” MoS(2) nanostructures, and the PANI film was controllably grown on the surface of ICNs and MoS(2). As a LIBs anode material, the ICN/MoS(2)/PANI electrode possesses excellent cycling performance, superior rate capability, and high reversible capacity. The reversible capacity retains 583 mA h/g after 400 cycles at a high current density of 2 A/g. The standout electrochemical performance of the ICN/MoS(2)/PANI electrode can be attributed to the synergistic effects of ICNs, MoS(2) nanostructures, and PANI. The ICN framework can buffer the volume change of MoS(2), facilitate electron transfer, and supply more lithium inset sites. The MoS(2) nanostructures provide superior rate capability and reversible capacity, and the PANI coating can further buffer the volume change and facilitate electron transfer.
