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 a crystalline iron hydroxide, in particular lepidocrocite (γ-FeOOH), by controlling the reaction time and the reaction temperature. Can be prepared, and by applying the produced high purity iron hydroxide to a positive electrode of a lithium-sulfur battery, it is possible to improve the discharge capacity and life characteristics of the battery.
