<P>PROBLEM TO BE SOLVED: To provide a cathode active material with a metal doped, a cathode and a lithium battery containing the active catode material. <P>SOLUTION: The cathode active material contains a lithium metal oxide of a chemical formula 1: Li[Li<SB>x</SB>Me<SB>y</SB>M<SB>z</SB>]O<SB>2+d</SB>. In the formula, x+y+z=1, 0<x<0.33, 0<z<0.1, 0≤d≤0.1, Me is one or more metals selected from a group composed of Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Al, Mg, Zr and B, and M is one or more metals selected from a group composed of Mo, W, Ir, Ni and Mg. <P>COPYRIGHT: (C)2009,JPO&INPIT |
