            Li 1-X-a A X Ni 1-Y-b B Y O₂.


    wherein: A is at least one alkaline earth metal component and may be selected. from (1) at least two of magnesium, calcium, strontium and barium, (2) strontium alone and (3) barium alone;
       B is at least one transition metal element other than Ni;
       X is the total number of moles of A and if A consists of more than one alkaline earth metal element, then X is the total number of moles of all alkaline earth metal elements;
       Y is the total number of moles of B and if B consists of more than one transition metal element, then Y is the total number of moles of all transition metal elements; and
       X, Y, a and b satisfy the respective equations: 0 0 -0.10 ≦ a ≦ 0.10 -0.15 ≦ b ≦ 0. 15.
    A method of preparing the cathode material comprises the steps of: mixing a starting compound containing lithium and A with a starting compound containing nickel and B; heating the mixture in an oxidizing atmosphere.

    摘要: Disclosed are a transition metal precursor for preparation of a lithium composite transition metal oxide, the transition metal precursor including a composite transition metal compound represented by Formula 1 below and a hydrocarbon compound, and a method of preparing the same:

             Mn a M b (OH 1-x ) 2      (1)

    wherein M is at least two selected from the group consisting of Ni, Co, Mn, Al, Cu, Fe, Mg, B, Cr, and second period transition metals; 0.4≤a≤1; 0≤b≤0.6; a+b≤1; and 0
    The transition metal precursor includes a particular composite transition metal compound and a hydrocarbon compound, and thus, when a lithium composite transition metal oxide is prepared using the same, carbon may be present in lithium transition metal oxide particles and/or on surfaces thereof, whereby a secondary battery including the lithium composite transition metal oxide exhibits excellent rate characteristics and long lifespan.
