Beschreibung
Zusammenfassung:	A composite oxide comprising lithium and a transition metal, wherein at least a portion of the composite oxide has a crystal lattice of a hexagonal lattice, and an electron beam diffraction image obtained by irradiating an electron beam from a direction includes a first diffraction spot group and a second diffraction spot group, n being an integer of 1 or more, the first diffraction spot group has a {-3 1 8/n} spot and a {1 2 2/n} spot that appear in correspondence with a period of a unit lattice of the hexagonal lattice, and the second diffraction spot group has six spots that appear between a central {0 0 0} spot and the {-3 1 8/n} spot with a 1/7 period, and six spots that appear between the central {0 0 0} spot and the {1 2 2/n} spot with a 1/7 period.
