CATHODE FOR LITHIUM-SULFUR BATTERY AND METHOD FOR PREPARING THE SAME

摘要

The present invention relates to a positive electrode for a lithium-sulfur battery and a producing method thereof. The positive electrode for a lithium-sulfur battery according to the present invention comprises: a conductive structure which includes conductive carbon and a concave pattern unit only on any one side; a positive electrode active material provided inside the concave pattern unit; and a lithium ion exchange membrane (LEM) provided on a surface having the concave pattern unit of the conductive structure. The lithium-sulfur battery can prevent structure collapse of the positive electrode and increase durability of the positive electrode.
