About phase : The coexistence of rhombohedral LiTMO 2 (TM=Ni, Co, or Mn) and monoclinic Li 2 MnO 3 ‐like structures inside Li 1.2 Mn 0.567 Ni 0.166 Co 0.067 O 2 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).
