| 제목 | Synthesis and high lithium-ion conductivity of Al-doped cubic garnet Li7La3Zr2O12 (LLZO) |
| 초록 | Al-doped cubic Li7La3Zr2O12 (LLZO) was successfully synthesized by a sol-gel method and electrochemically characterized. Polycrystalline powders of c-LLZO were prepared from the molecular mixtures of lithium Nitrate, lanthanum nitrate, zirconium nitrate and aluminum nitrate and subsequent annealing of the dried precursor sol at 900℃ for 2 h in air condition. Phase formation was studied by X-ray powder diffraction. Al doping was necessary for the preparation of cubic LLZO ceramics crystallizing and found to facilitate the formation of the cubic garnet modification at lower synthesis temperature. The ionic conductivity of cubic LLZO was found to increase by Al doping. The highest ionic conductivity in room temperature of cubic LLZO was 0.2 mS cm−1. |
