Abstract

A method for preparing Iron Oxide-hydroxide (FeOOH), and a positive electrode for a lithium-sulfur battery including Iron Oxide-hydroxide. In particular, the preparation of crystalline Iron Oxide-hydroxide, particularly, lepidocrocite (γ-FeOOH), by controlling a reaction time and a reaction temperature, and by using the prepared high purity Iron Oxide-hydroxide in a positive electrode of a lithium-sulfur battery, may enhance discharge capacity and lifetime properties of the battery.
