CATHODE SLURRY FOR LITHIUM-SULFUR BATTERY, CATHODE FOR LITHIUM-SULFUR BATTERY MANUFACTURED USING SAME, AND LITHIUM-SULFUR BATTERY COMPRISING SAME

The present invention relates to a positive electrode slurry for a lithium-sulfur battery, a positive electrode for a lithium-sulfur battery manufactured using the same, and a lithium-sulfur battery including the same, and more particularly, to a positive electrode slurry for a lithium-sulfur battery comprising a positive electrode active material, an electrically conductive material, a binder and a solvent, wherein the ratio of the average particle diameter (D) of the positive electrode active material and the positive electrode slurry is 1.5 or less, and the phase angle at 1 Hz of the positive electrode slurry is 50° or more. The positive electrode slurry for the lithium-sulfur battery of the present invention exhibits excellent flowability even while having a high solid content, thereby making it possible to manufacture a positive electrode for a lithium-sulfur battery with excellent electrochemical properties and improving the productivity and economic feasibility of the manufacturing process of the positive electrode for the lithium-sulfur battery.
