COMPOSITE POSITIVE ELECTRODE ACTIVE MATERIAL AND POSITIVE ELECTRODE AND LITHIUM BATTERY COMPRISING THE COMPOSITE POSITIVE ELECTRODE ACTIVE MATERIAL |
| 摘要 |
A composite positive electrode active material includes a lithium transition metal oxide represented by at least one of LiNixCoyMnzO2 (Formula 1) and aLi2MnO3.(1−a)LiMO2 (Formula 2). In Formula 1, and a vanadium-based compound including a polyanion. In Formula 1, 0<x≦0.8, 0<y≦0.5, and 0<z≦0.5. In Formula 2, 0<a<1 and M is at least one element selected from aluminum (Al), magnesium (Mg), manganese (Mn), cobalt (Co), chromium (Cr), vanadium (V), iron (Fe), and nickel (Ni). |
