Hybrid Structures of Sisal Fiber Derived Interconnected Carbon Nanosheets/MoS2/Polyaniline as Advanced Electrode Materials in Lithium-Ion Batteries

Abstract

In this work, we designed and successfully synthesized an interconnected carbon nanosheet/MoS2/polyaniline hybrid (ICN/MoS2/PANI) by combining the hydrothermal method and in situ chemical oxidative polymerization. The as-synthesized ICNs/MoS2/PANI hybrid showed a “caramel treat-like” architecture in which the sisal fiber derived ICNs were used as hosts to grow “follower-like” MoS2 nanostructures, and the PANI film was controllably grown on the surface of ICNs and MoS2. As a LIBs anode material, the ICN/MoS2/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/MoS2/PANI electrode can be attributed to the synergistic effects of ICNs, MoS2 nanostructures, and PANI. The ICN framework can buffer the volume change of MoS2, facilitate electron transfer, and supply more lithium inset sites. The MoS2 nanostructures provide superior rate capability and reversible capacity, and the PANI coating can further buffer the volume change and facilitate electron transfer.

PEG–PVP-Assisted Hydrothermal Synthesis and Electrochemical Performance of N-Doped MoS2/C Composites as Anode Material for Lithium-Ion Batteries

“…Therefore, large-scale electrochemical energy storage devices with high capacity are crucial for the efficient utilization of clean energy. − In addition, the rapid development of portable electronic devices has also put forward higher requirements for the performance of the secondary battery. Lithium-ion batteries (LIBs) have attracted much attention and good application prospects in the field of energy storage due to their advantages such as relatively high volumetric energy density, rapid charge/discharge capacity, long cycle life, and better safety performance. − As an important component of LIBs, the anode material materials have become the key point to improve the electrochemical performances of LIBs.…”

“…The results showed that the electrode exhibited a capacity of 814.2 mAh g −1 at 100 mA g −1 after 50 cycles. Li [ 20 ] 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. This caramel treat‐like ICN/MoS 2 /PANI hybrid delivered a high reversible capacity of 583 mAh g −1 after 400 cycles at 2.0 A g −1 , which was much higher than that of graphite, indicating its potential for LIB applications.…”
