CATHODE FOR LITHIUM SULFUR BATTERY AND METHOD FOR PREPARING THEREOF |
| 摘要 |
Disclosed is a cathode for a lithium sulfur battery comprising a sulfur-containing active material, an electrolyte in which a lithium salt is dissolved in an ether-based solvent, and an additional liquid active material in the form of Li2Sx (0<x≦9) dissolved in the electrolyte, and a lithium sulfur battery using the same. The lithium sulfur battery of the present invention has a loading amount of cathode sulfur that is increased to at least about 13.5 mg/cm2 and a structural energy density that is increased from about 265 Wh/kg to at least about 355 Wh/kg as compared with a conventional battery. |
