| abstract |
A composite oxide which contains lithium and a transition metal, wherein: the crystal lattice of at least a part of the composite oxide is a hexagonal lattice; with n being an integer of not less than 1, an electron beam diffraction image thereof as acquired by having an electron beam enter from the direction of <2 -2 1> has a first group of diffraction spots and a second group of diffraction spots; the first group of diffraction spots comprises a (-3 1 8/n) spot and a (1 2 2/n) spot, which respectively appear in correspondence with the period of the unit lattice of the hexagonal lattice; and the second group of diffraction spots comprises 6 spots that appear with a 1/7 period between a (0 0 0) spot in the center and the (-3 1 8/n) spot, and 6 spots that appear with a 1/7 period between the (0 0 0) spot in the center and the(1 2 2/n) spot. |
