Abstract A novel molybdenum disulfide/carbon (MoS2/C) nanocomposite is synthesized by a simple hydrothermal method using glucose as a carbon source and Pluronic F127 as promoting agent in presence of MoS2 nanoparticles and followed by carbonization. Pluronic F127 is used as an essential agent which inhibits the spontaneous formation of carbon microspheres during the hydrothermal reaction. The composite electrode exhibits excellent cycling stability and rate capability, delivering a reversible capacity of 882.6 mA h g−1 at a current density of 50 mA g−1 and a capacity retention of 82.8% after 100 cycles at a current density of 100 mA g−1. At a higher current density of 300/500 mA g−1, it still retains a capacity of 603.6/461.6 mA h g−1 respectively, as compared to 295.6/228.4 mA h g−1 for the pristine MoS2 electrode. The composite shows favorable electrochemical kinetics compared with pristine MoS2 due to the incorporation of homogenous conductive carbon layer and its nanostructured morphology.

一种新型 MoS 2 /C 纳米复合材料作为锂离子电池负极材料

摘要 以葡萄糖为碳源，Pluronic F127 为促进剂，在二硫化钼纳米颗粒存在下，通过简单的水热法合成了一种新型二硫化钼/碳（MoS2/C）纳米复合材料，然后进行碳化。Pluronic F127 用作抑制水热反应过程中碳微球自发形成的基本试剂。该复合电极表现出优异的循环稳定性和倍率性能，在电流密度为 50 mA g-1 时的可逆容量为 882.6 mA hg-1，在电流密度为 100 mA g-1 的情况下循环 100 次后容量保持率为 82.8%。 1. 在 300/500 mA g-1 的更高电流密度下，与原始 MoS2 电极的 295.6/228.4 mA h g-1 相比，它仍分别保持 603.6/461.6 mA h g-1 的容量。
