摘要：
In this study, LiMn2O4 was fabricated with "Nano Inclusions" and the detailed crystal structure of the sample was studied by HAADF-STEM observation with an electron beam tilted to the specimen, electron diffraction, HRTEM observation. HAADF-STEM observation and electron diffraction revealed that the "Nano Inclusions" were located within single LiMn2O4 crystals. HRTEM observation clarified that the (100) plane of LiMn2O4 and the (110) plane of ZnMn2O4 have a common cubic close-packed oxygen arrangement and connect to each other without forming grain boundaries, due to similar atomic arrangements of LiMn2O4 along the < 100 > direction and of ZnMn2O4 along the [110] and [110] direction.
