| 摘要 |
The present invention relates to a lithium secondary battery, including a positive electrode with a positive electrode mixture, a negative electrode with a negative electrode mixture, and a non-aqueous electrolyte solution, wherein the positive electrode is a conductive material and comprises (i) nanosized carbon based particles and (ii) carbon based fibers having a length which is one to three times longer than that of average particle size to directly connect positive electrode particles electrically; and the negative electrode is a negative electrode active material and comprises (i) carbon based active materials and (ii) a lithium titanium oxide (LTO). Therefore, the lithium secondary battery has a high energy density and accordingly has high capacity, thereby having excellent output and lifespan properties. |
