The present invention relates to a carbon-based fiber sheet and a lithium-sulfur battery comprising the same. The carbon-based fiber sheet for lithium-sulfur battery according to the present invention has a high concentration of nitrogen doped to adsorb lithium polysulfide eluted from the anode during charging and discharging to prevent diffusion, thereby inhibiting the shuttle reaction to prevent lithium- The capacity and lifespan characteristics of the sulfur battery can be improved. |
