| 제목 | Ordered Mesoporous Transition Metal Oxides : Energy Storage for Lithium-Sulfur Cathode |
| 초록 | Lithium–sulfur batteries are upcoming electrochemical devices due to its advantages such as high specific capacity and energy density. Despite its superiority, practical use of Li–S battery is impeded because of obstacles; insulating character of sulfur and dissolution of polysulfide Intermediates. Majority of studies have focused on porous carbon materials not only to impart sulfur conductivity but also to capture polysulfide by physisorption. In this work, we present new possibility of porous metal oxides (MOx) for Li–S battery cathode as host material. We expect that our cathode can effectively trap polysulfide by chemisorption and retard the dissolution of it. Consequently, it results in better cycling performance. Ordered mesoporous MOx (TiO2, MnO, NiO) were synthesized by a nano-replication method via ordered mesoporous silica (KIT-6). The materials were characterized by X-ray diffraction, N2 adsorption/desorption, scanning electron microscopy. |
