LITHIUM-SULFUR BATTERY POSITIVE ELECTRODE MATERIAL, MANUFACTURING METHOD, AND LITHIUM-SULFUR SECONDARY BATTERY USING THE SAME

An object of the invention is to provide a lithium-sulfur battery positive electrode material that makes it possible to prevent a shuttle effect that may occur during cycling in a lithium-sulfur battery and the deterioration of the lifespan due to a large volume change of the positive electrode, and a manufacturing method for the lithium-sulfur battery positive electrode. To achieve such an object as described above, a lithium-sulfur battery positive electrode material according to the invention includes a nitrogen-doped carbon nanotube and sulfur arranged in an inside of the carbon nanotube, in which transition metal sulfide nanocrystals are dispersed on a surface of the carbon nanotube.
