Abstract:
1. Lithium nickel manganese cobalt composite oxide having a composition of Li a Ni x Mn y Co z O 2 (x+y+z=1, 1.05<a<1.3), wherein, in the data obtained by measuring a Raman spectrum of the composite oxide, the peak intensity of an Eg oscillation mode of a hexagonal crystal structure located at 480 to 495 cm −1 and the peak intensity of an F2g oscillation mode of a spinel structure located at 500 to 530 cm −1 in relation to the peak intensity of an A1g oscillation mode of a hexagonal crystal structure in which the main peak is located at 590 to 610 cm −1 are both respectively 15% or higher and 40% or lower than the peak intensity of the A1g oscillation mode of a hexagonal crystal structure as the main peak.
