Lithium Secondary Battery |
| 摘要 |
The present invention relates to a lithium secondary battery, and more specifically, to a lithium secondary battery including a cathode, an anode and a non-aqueous electrolyte solution, where the cathode includes a cathode active material including a lithium-metal oxide which is doped with a transition metal and includes at least one type of metal having a concentration gradient region between a central portion and a surface portion, and thus having a significantly increased charge/discharge capacity and output at a low temperature to exhibit excellent properties in the low-temperature environment. |
