Sulfur-carbon composite, preparation method therefor, and lithium-sulfur battery comprising same |
| abstract |
A sulfur-carbon composite including a carbon-based material of which surface is modified by acid treatment is provided, as well as a method for preparing the same, and a lithium-sulfur battery including the same. A sulfur-carbon composite suppresses polysulfide elution when used as a positive electrode active material of a lithium-sulfur battery by including a carbon-based material of which surface is modified to have a hydroxyl group and a carboxyl group capable of adsorbing polysulfide on the surface. Accordingly, capacity property and life time property of the battery may be enhanced. In addition, a surface of the carbon-based material can be modified using a simple process of treating with a mixed solution of nitric acid and sulfuric acid, and a content of functional groups on the surface can be controlled depending on a mixing ratio of the nitric acid and the sulfuric acid. |
