Title:
CARBON-BASED FIBER SHEET AND LITHIUM-SULFUR BATTERY INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2017/209383
Kind Code:
A1
Abstract:
The present invention relates to a carbon-based fiber sheet and a lithium-sulfur battery including the same. According to the present invention, a carbon-based fiber sheet for a lithium-sulfur battery is doped with highly concentrated nitrogen so as to perform roles of adsorbing lithium polysulfide eluted from a cathode during charging or discharging and of preventing the diffusion thereof, such that a shuttle reaction is suppressed, thereby enabling capacity and lifespan characteristics of a lithium-sulfur battery to improve.
