摘要

MoS2-derived carbon nanomaterials have garnered significant interest as anode materials for lithium-ion batteries (LIBs). MoS2-based carbon nanomaterials are synthesized using a two-step or multi-step method. Herein, we report a simple one-step arc-discharge technique for the synthesis of MoS2 nanoparticles loaded on S-doped carbon nanohorns (MoS2/SCNHs). The synthesized MoS2/SCNHs serve as an anode material for LIBs, demonstrating a substantial reversible capacity of 480.4 mAh g−1 at a current density of 1.0 A g−1 after 550 cycles. The elevated specific capacity and extended lifespan are primarily ascribed to a distinctive bud-type morphology of SCNHs. The microporous structure of the SCNHs significantly reduces charge-transfer resistance and effectively prevents the aggregation of MoS2 nanoparticles. The MoS2/SCNHs hybrid material synthesized via the arc-discharge method is a promising anode for LIBs, and this method offers a novel approach for producing other transition metal sulfides supported on carbonaceous substrates.
