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 having excellent electrochemical stability, and to a producing method thereof. The producing method of the positive electrode for a lithium-sulfur battery comprises the steps of: 1) mixing a positive electrode active material and an organic solvent to produce a positive electrode active material-dissolved solution; 2) immersing a porous structure having conductivity into the positive electrode active material-dissolved solution; and 3) recrystallizing the positive electrode active material through quick cooling and drying processes and impregnating the recrystallized positive electrode active material on a surface of the porous structure and in at least one portion inside the porous structure.
