Abstract:
1. A method for preparing a lithium mixed transition metal oxide, comprising subjecting Li 2 CO 3 and a mixed transition metal precursor to a solid-state reaction under an oxygen-deficient atmosphere having an oxygen concentration of 10 to 50% by volume to thereby prepare a powdered lithium mixed transition metal oxide having a composition represented by Formula I: wherein: M=M′ A is a dopant; 0≦k<0.05; and x+y=2 and 0.95≦x≦1.05, wherein the mixed transition metal precursor has a tap density of 1.1 to 1.6 g/cm
