Lithium-manganese-nickel-cobalt mixed oxide (I) is new, where (I) exhibits a Brunauer Emmett Teller surface of 3-20 m 2>/g, a multimodal particle size distribution and an average particle diameter of = 5 mu m. Lithium-manganese-nickel-cobalt mixed oxide of formula (Li xMn(0.5-a)Ni(0.5-b)CO(a+b)O 2) (I) is new, where (I) exhibits a Brunauer Emmett Teller surface of 3-20 m 2>/g, a multimodal particle size distribution and an average particle diameter of = 5 mu m. x : 0.8-1.2; a, b : 0.05-0.3; a-b : -0.1 to 0.02; and a+b : less than 0.5. Independent claims are included for: (1) the preparation of mixed oxide (I); (2) a mixed oxide (I) (in which a-b is -0.11 to 0.02) (Ia), where (Ia) exhibits a Brunauer Emmett Teller surface of 0.05-1 m 2>/g, an average particle size of = 10 mu m and a X-ray diffraction in which the ratio of the intensities of the signals at 2theta of 18.661+- 1[deg] to 2theta of 44+- 1[deg] is >= 2.4; and (3) the preparation of mixed oxide (Ia). |
