<P>PROBLEM TO BE SOLVED: To provide a cathode active material for lithium secondary battery excellent in volume capacity density, safety, uniform painting property, charging/discharging cycle durability at high charging voltage, and low temperature property. <P>SOLUTION: The lithium containing compound oxide expressed by general formula; Li<SB>p</SB>N<SB>x</SB>M<SB>y</SB>L<SB>z</SB>O<SB>q</SB>F<SB>a</SB>is manufactured by calcinating a mixture of a raw material of lithium, a raw material of N element, a raw material of M element, a raw material of L element, and a raw material of fluorine contained as occasion calls, in oxygen-containing atmosphere. (In the formula, N is at least one kind of element chosen from Co, Mn, and Ni; M is aluminum or a transition metal element; L is at least one kind of element chosen from phosphor, boron, silicon, and an alkali earth metal element; 0.9≤p≤1.1, 0.97≤x<1.00, 0<y≤0.03, 0<z≤0.03, 1.9≤q≤2.1, x+t+z=1, 0≤a≤0.02.), and an organic metal compound having a structure of M-O-L in a molecule is utilized as a raw material. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
