POSITIVE ELECTRODE INCLUDING SULFUR-CARBON COMPOSITE AND LITHIUM-ION SECONDARY BATTERY INCLUDING THE SAME

Disclosed is a positive electrode for a lithium-sulfur battery. The positive electrode includes a sulfur-carbon composite as a positive electrode active material. The sulfur-carbon composite includes a porous carbonaceous material having a high specific surface area and a specific range of particle diameter. A lithium-sulfur battery using the sulfur-carbon composite shows reduced initial irreversible capacity and has improved output characteristics and life characteristics.
