Abstract
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.
二硫化钼衍生的碳纳米材料作为锂离子电池（LIBs）的负极材料已经引起了人们的极大兴趣。采用两步法或多步法合成了二硫化钼基碳纳米材料。在此，我们报道了一种简单的一步电弧放电技术，用于合成负载在s掺杂碳纳米角（MoS2/SCNHs）上的MoS2纳米颗粒。合成的MoS2/SCNHs作为锂离子电池的阳极材料，在电流密度为1.0 a g−1的情况下，经过550次循环，显示出480.4 mAh g−1的可观可逆容量。比容量的提高和寿命的延长主要归因于SCNHs独特的芽型形态。SCNHs的微孔结构显著降低了电荷转移阻力，有效地阻止了MoS2纳米粒子的聚集。电弧放电法制备的MoS2/SCNHs杂化材料是一种很有前途的锂离子电池阳极，为制备其他碳质衬底上的过渡金属硫化物提供了新的途径。图形抽象
