Cathode active materials for lithium batteries are provided. In one embodiment, the cathode active material is a lithium complex material represented by the following Formula: yLi[Li 1/3 Me 2/3 ]O 2 -(1-y)LiMe'O 2 . In the formula, 0<y‰ 0.8, Me is a metal group having an oxidation number of +4 and includes a transition metal selected from Mo, W, V, Ti, Zr, Ru, Rh, Pd, Os, Ir, Pt and combinations thereof, and Me' includes a transition metal selected from Ni, Mn, Co and combinations thereof. Lithium batteries employing the cathode active materials are also provided and exhibit improved energy density and high-rate capabilities of an electrode. |
