Abstract
A positive electrode of a lithium secondary battery including an iron oxide as an additive, and a lithium secondary battery including the positive electrode. In the case of a lithium secondary battery including a positive electrode to which iron oxide is applied, the iron oxide adsorbs the lithium polysulfide (LiPS) generated in the charging/discharging process of the lithium secondary battery, thereby exhibiting an effect of increasing the charging/discharging efficiency of the battery and improving the lifetime characteristics.
