Lithium composite metallic oxide and production process for the same

A lithium composite metallic oxide expressed by a general formula, LiaNibCocMndDeOf where 0.2≤“a”≤1.5, “b”+“c”+“d”+“e”=1, 0<“e”<1,“D” is at least one element selected from the group consisting of Fe, Cr, Cu, Zn, Ca, Mg, Zr, S, Si, Na, K, Al, Ti, P, Ga, Ge, V, Mo, Nb, W, La, Hf, and Rf, and 1.7≤“f”≤2.1;

• the lithium composite metallic oxide comprising:
• a high manganese portion, which is made of a metallic oxide including Ni, Co and Mn at least and of which the composition ratio between Ni, Co and Mn is expressed by Ni:Co:Mn=g:h:i where “g”+“h”+“i”=1, 0<“g”<1, 0<“h”<“c”, and “d”<“i”<1, in a superficial layer thereof;
• and
• a metallic oxidation portion in an outermost superficial layer of the high manganese portion,
• the metallic oxidation portion is expressed by a formula LiqM2O3+r, where 0<“q”<1, 0≤“r”<1, M is a metal selected from the group consisting of Ni, Co and Mn, and
• the composition of the metallic oxidation portion is different from the composition of the high manganese portion;

• a first-composition portion expressed by a general formula, Lia1Nib1Coc1Mnd1De1 Of1 where 0.2≤“a1”≤1.5, “b1”+“c1”+“d1”+“e1”=1, 0<“e1”<1, “D” is at least one element selected from the group consisting of Fe, Cr, Cu, Zn, Ca, Mg, Zr, S, Si, Na, K, Al, Ti, P, Ga, Ge, V, Mo, Nb, W, La, Hf and Rf, and 1.7≤“f1”≤2.1;
• and
• a second-composition portion expressed by a general formula, Lia2Nib2Coc2Mnd2De2Of2where 0.2≤“a2”≤1.5, “b2”+“c2”+“d2”+“e2”=1, 0<“e2”<1, “D” is at least one element selected from the group consisting of Fe, Cr, Cu, Zn, Ca, Mg, Zr, S, Si, Na, K, Al, Ti, P, Ga, Ge, V, Mo, Nb, W, La, Hf and Rf, and 1.7≤“f2”≤2.1 where at least any of the following is satisfied:
