Abstract
A lithium-sulfur battery separator includes a separator substrate and a functional layer coated on the separator substrate. The functional layer includes a carbon nanotube layer and a hafnium oxide layer. The carbon nanotube layer includes a plurality of carbon nanotubes. The hafnium oxide layer includes a plurality of hafnium oxide nanoparticles. The hafnium oxide nanoparticles are adsorbed on surfaces of the carbon nanotubes. The present disclosure also relates to a lithium-sulfur battery comprising the lithium-sulfur battery separator.
