LITHIUM SECONDARY BATTERY |
摘要 |
The present invention relates to a lithium secondary battery including a negative electrode and a positive electrode, wherein the negative electrode includes a first negative electrode active material made of a carbonaceous material, and a second negative electrode active material having a lower initial charge/discharge efficiency than the first negative electrode active material, and the initial charge/discharge efficiency of the negative electrode is lower than the initial charge/discharge efficiency of the positive electrode. The present invention provides a lithium secondary battery capable of realizing high output by remarkably reducing the resistance at a low state-of-charge (SOC) level. |
