Abstract: The present invention provides an organic sulfur material comprising carbon, hydrogen, and sulfur as constituent elements, and having peaks in the vicinity of 480 cm−1, 1250 cm−1, 1440 cm−1, and 1900 cm−1 in a Raman spectrum detected by Raman spectroscopy. The peak in the vicinity of 1440 cm−1 is the most intense peak. This organic sulfur material, which is produced by using a liquid organic starting material, achieves high capacity. This organic sulfur material preferably does not have peaks in the vicinity of 846 cm−1 or 1066 cm−1.

Abstract: A positive electrode active material for a lithium-sulfur battery, and more particularly, to a positive electrode active material for a lithium-sulfur battery including metal sulfide nanoparticles and a preparation method thereof. The metal sulfide nanoparticles with large specific surface area applied to the positive electrode active material for the lithium-sulfur battery according to the present invention acts as a redox mediator during charging and discharging of the lithium-sulfur battery, thereby reducing the shuttle response by not only inhibiting the formation itself of polysulfides with elution properties, but also, even if polysulfides are eluted, adsorbing them and thus preventing them from diffusing into the electrolyte solution, and thus the capacity and life characteristics of the lithium-sulfur battery can be improved.
