POSITIVE ACTIVE MATERIAL FOR RECHARGEABLE LITHIUM BATTERY AND RECHARGEABLE LITHIUM BATTERY |
| 摘要 |
A positive active material for a rechargeable lithium battery includes a lithium nickel composite oxide having an I(003)/I(104) ratio of greater than or equal to about 0.92 and less than or equal to about 1.02 in X-ray diffraction, wherein the I(003)/I(104) ratio is a ratio of a diffraction peak intensity I(003) of a (003) phase and a diffraction peak intensity I(104) of a (104) phase. The lithium nickel composite oxide includes lithium and a nickel-containing metal, and nickel is present in an amount of greater than or equal to about 80 atm % based on the total atom amount of the nickel-containing metal. A rechargeable lithium battery includes the positive active material. |
