LITHIUM COMPOSITE OXIDE AND MANUFACTURING METHOD THEREFOR |
| 摘要 |
The present invention relates to a lithium composite oxide and a manufacturing method therefor and, more specifically, to: a lithium composite oxide in which the concentration of manganese forming the lithium composite oxide exhibits a concentration gradient in the entirety of the particles from the center to the surface, and comprising secondary particles formed from the condensing of stick-shaped primary particles; and a manufacturing method thereof. |

1. A lithium composite oxide comprising:
a first interior formed of secondary particles concentrated with a plurality of stick-shaped primary particles, formed in a radius of r1 (0.2 μm≦r1≦5 μm) from the center of the particle, and given in Formula 1 that is Lia1Nix1Coy1Mnz1O2+δ; and a second interior formed to a radius of r2 (r1≦10 μm) from the center of the particle and given in Formula 2 that is Lia2Nix2Coy2Mnz1O2+δ (in the Formula 1 and the Formula 2, 0<a1≦1.1, 0<a2≦1.1, 0≦x2≦1, 0≦y2≦1, 0.05≦z1≦1, 0.15≦z2≦1, 0.15≦z2≦1, 0≦w≦0.1, 0.0≦δ≦1, Z1≦Z2). |
