| 제목 | Nanostructure controlled MoS2 anode material for sustainable sodium ion batteries |
| 초록 | Inspired by the success of graphite anodes in lithium-ion batteries, anode materials capable of inserting sodium ions within the layer structure are considered to provide stable and reversible electrochemical Na+ storage for sodium-ion battery applications. Among various anode materials for sodium-ion batteries, MoS2 attracted attention due to its layer structure and insertion properties. Here, we present MoS2 grown vertically on nitrogen reduced graphene oxide (N-RGO) with sheet density and controlled sheet density and MoS2 sheet height as a negative electrode active material for sodium-ion batteries. By adjusting the nucleation and growth process, we control the height and density of the MoS2 sheet. High sheet density can prevent additional SEI layers, and the shortened sheet length of MoS2 reduces the resistance of Na+ diffusion. Growth of MoS2 sheets on N-RGO was observed by scanning electron microscopy and high resolution transmission electron microscopy. |
