Abstract
The present invention provides a lithium composite metal oxide containing Li and at least one transition metal element, wherein at least one lithium composite metal oxide particle constituting the lithium composite metal oxide has both hexagonal and monoclinic crystal structures. Further, the present invention also provides a lithium composite metal oxide containing Li, Ni and M (where, M represents one or more kinds of transition metal elements selected from the group consisting of Mn, Co and Fe), having a diffraction peak (diffraction peak A) at an angle 2θ in a range from 20° to 23° in a powder X-ray diffraction pattern of a lithium composite metal oxide which is obtained by powder X-ray diffraction measurement made in the condition that CuKα is used as a radiation source and the measurement range of diffraction angle 2θ is in a range from 10° to 90°.
