dc.description.abstractThe present invention relates to a separator for a lithium-sulfur battery having a composite coating layer including polydopamine, and a method for preparing the same, and in particular, to a lithium-sulfur battery suppressing lithium polysulfide elution by using a composite coating layer including polydopamine and a conductive material on one surface of a separator. In the lithium-sulfur battery according to the present invention, a porous structure of polydopamine adsorbs lithium polysulfide eluted from a positive electrode preventing elution and diffusion, and by providing additional electric conductivity, a reaction site of a positive electrode active material is provided, and therefore, battery capacity and life time properties are enhanced.-
