Cathode active material and lithium secondary batteries comprising the same |
| abstract |
The present invention is fluorine, including a lithium metal composite oxide of the doped layer structure, and measuring the impedance of the half-cell is applied to the positive electrode active material resulting positive electrode per unit area of the electrode (cm 2) per [the resistance of the electrolyte (R S) + electrode Wherein a solid electrolyte interface ( SEI ) resistance (R SEI ) and a charge transfer resistance (R CT ) formed on the surface of the cathode active material are in the range of 8 Ω to 30 Ω. According to the present invention, a fluorine-doped lithium metal composite oxide is used as a cathode active material It is possible to provide a lithium secondary battery having a low impedance, thereby improving the discharge capacity and rate characteristics of the lithium secondary battery. |
