LITHIUM-SULFUR BATTERY SEPARATOR

A lithium-sulfur battery separator includes a PSL and a FL. The FL is located on a surface of the PSL. The FL comprises carbon nanotube structure and a plurality of MoPnanoparticles. The carbon nanotube structure defines a plurality of micropores. The plurality of MoPnanoparticles is located on surface of the carbon nanotube structure and filled in micropores in the carbon nanotube structure.
