Synthesis of P-ordered Meso-Microporous Core-Shell carbon (P-MMCS) for Li-S battery |
| 초록 |
Li-ion battery is most widely used rechargeable battery but the practical application for electric vehicles and ESS is hindered due to its low capacity. So many alternatives are rising and one of them is Li-S battery. Li-S batteries have high capacity but active material sulfur dissolves as polysulfides 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 (P-MMCS) was synthesized by nanocasting method using SBA-15 as template and coating method. We controlled the amount of phosphoric acid and coating thickness this time. The as-synthesized materials were characterized by X-ray diffraction(XRD), N2-sorption isotherm and scanning electron microscope(SEM). |
