METHOD FOR PREPARING FeOOH, AND CATHODE FOR LITHIUM-SULFUR BATTERY COMPRISING FeOOH

摘要

The present invention relates to a method for producing iron hydroxide (FeOOH) and a positive electrode for a lithium-sulfur battery containing iron hydroxide, and more particularly, to crystalline iron hydroxide, particularly lepidochrosite (γ-FeOOH) by controlling the reaction time and reaction temperature. can be manufactured, and the prepared high-purity iron hydroxide can be applied to the positive electrode of a lithium-sulfur battery to improve the discharge capacity and lifespan characteristics of the battery.
