About phase: The coexistence of rhombohedral LiTMO2 (TM=Ni, Co, or Mn) and monoclinic Li2MnO3-like structures inside Li1.2Mn0.567Ni0.166Co0.067O2 is revealed directly at atomic resolution. The hetero-interface along the [001]rh/[103]mon zone axis direction is demonstrated, indicating the two-phase nature of these lithium-rich cathode materials (green Li, blue Mn, red O, cyan TM).
在 Li1.2Mn0.567Ni0.166Co0.067O2 中直接以原子分辨率揭示了菱面体 LiTMO2(TM=Ni、Co 或 Mn)和单斜 Li2MnO3 类结构的共存。沿[001]rh/[103]mon 区轴方向的异质界面得到了证明,表明这些富锂正极材料具有两相性质(绿色 Li、蓝色 Mn、红色 O、青色 TM)。
