Abstract
A positive electrode of a lithium-sulfur battery including maghemite as an additive and a lithium-sulfur battery including the same. The maghemite obtained by heat treatment of lepidocrocite adsorbs lithium polysulfide (LiPS) generated from a lithium-sulfur battery, thereby improving the charging/discharging efficiency and capacity of the battery, as well as increasing the life of the battery.
