Abstract
A lithium-containing composite oxide essentially containing Li, Ni, Co and Mn, which has a crystal structure with space group R-3m, with a c-axis lattice constant being from 14.208 to 14.228 Å, and with an a-axis lattice constant and the c-axis lattice constant satisfying the relation of 3a+5.615≤c≤3a+5.655, and of which the integrated intensity ratio (I/I) of the (003) peak to the (104) peak in an XRD pattern is from 1.21 to 1.39.
