| 제목 | Ordered Mesoporous Nickel Manganese Oxide: High Electrochemical Performance in LIB |
| 초록 | In the previous researches, it is reported that ordered mesoporous anode materials showed buffer effect against volume expansion during lithiation of electrode. Among various transition metal oxide electrodes, manganese oxide showed high capacity with low operation voltage, but low initial efficiency. In order to overcome this disadvantage, we applied binary system to manganese oxide with NiO due to catalytic behavior of NiO on SEI decomposition. Therefore, we designed ordered mesoporous nickel manganese oxide (NMO) for higher electrochemical performance than manganese oxide, and advantages of ordered mesoporous structure in this study. We successfully prepared ordered mesoporous NMO, Mn2O3, and NiO via nano-casting method using KIT-6, and prepared materials were utilized as electrode materials in LIB. Mesoporous NMO exhibited higher initial coulombic efficiency (71%), better cycle performance, and higher rate capability than mesoporous single metal oxides. In conclusion, we developed ordered mesoporous anode material with electrochemical performance using binary system. |
