Cylindrical nanostructured MoS2 directly grown on CNT composites for lithium ion batteries |
| 초록 |
The direct attachment of MoS2 to carbonaceous architecture materials remains a major challenge because of the non-initimate contact between carbonaceous materials and active MoS2 material. In this study, we report a new unique synthesis method to produce a new type of hybrid nanostructure of MoS2-CNTs composites. We developed a novel strategy for the synthesis of cylindrical MoS2 directly grown on CNT composites without the use of any other additives, exhibiting super electrochemical performances as the anode material of lithium ion batteries via a microwave irradiation technique. We adopt a simple, step-by-step method: sulfur coating on CNTs and then reaction with a Mo source to synthesize hybrid cylindrical nanostructures of the MoS2-CNT composite. X-ray diffraction, field emission scanning electron microscopy, and high-resolution transmission electron microscopy analyses demonstrated that the as-synthesized MoS2-CNTs possessed a hybrid nanostructure in which MoS2 sheets were well attached to the CNTs. The directly attached MoS2 sheets on the CNTs showed superior electrochemical performance for anode materials of a lithium ion battery. |
