  "textContent": "The present invention relates to a sulfur electrode composition for a lithium-sulfur battery, comprising: a cellulose nanofiber binder; and an active material comprising sulfur. Thereby, the sulfur electrode for a lithium-sulfur battery of the present invention maximizes the utilization rate and conversion reaction rate of sulfur in a lithium-sulfur battery even under minimal electrolyte conditions by introducing cellulose nanofibers as a binder, and the distance between the expanded glucose chains formed due to the one-dimensional structure and electrostatic repulsion of the cellulose nanofibers promotes the interaction between the binder and lithium polysulfide (LiPS), and effectively suppresses the formation of aggregates of lithium polysulfide (LiPS). Therefore, a lithium-sulfur battery including such a sulfur electrode maintains a high active material ratio even under minimal electrolyte conditions while increasing the electrochemical conversion reaction rate, thereby improving battery performance and significantly increasing energy density.",
