Claim Text:
1. A lithium mixed transition metal oxide having a composition represented by Formula I and comprising mixed transition metal oxide (MO) layers comprising Ni ions, and reversible lithium layers which allow intercalation and deintercalation of lithium ions, wherein the MO layers and the reversible lithium layers are disposed alternately and repeatedly to form a layered crystal structure, and a portion of Ni ions derived from the MO layer are inserted into the reversible lithium layers at a level of 3% to 7% measured by Rietveld refinement of X-ray diffraction patterns to interconnect the MO layers and the reversible lithium layers: wherein: M=M′ A is a dopant; 0≦k<0.05; and x+y≈2 and 0.95≦x≦1.05.
