제목 | Preparation of Phosphorus Doped Ordered Meso and Microporous Core-Shell Carbon and Its Applications |
초록 | The rechargeable battery is in high demand to address increasing electric devices market. Li-ion battery is most widely used because of its high energy density and lightness, but the practical application for electric vehicles and ESS (Energy Storage System) is hindered due to its low capacity. So, various studies are under way to develop alternative batteries. Among them, Li-S battery has attracted much attention as the next-generation battery because it has high capacity and use low-cost active materials. However the active material, sulfur dissolves as polysulfides intermediates while charging and discharging. This makes the capacity decrease and followed by poor cycle performance. So, we tried to develop new cathode materials that can block the elution of polysulfides. In our study, P-ordered Meso-Microporous Core-Shell carbon (MMCS) was synthesized by nanocasting method using SBA-15 as hard template and by coating method. Here at, we controlled the amount of phosphoric acid and thickness of coated carbon. The as-synthesized materials were characterized by X-ray diffraction (XRD), N2-sorption isotherm and scanning electron microscope (SEM). |
