Abstract
The invention relates to a method for fabricating a regenerative polysulfide-scavenging layer (RSL). The method includes embedding nanowires or nanocrystals of metal oxides with a membrane of carbon nanotubes (CNTs); and forming the RSL with the embedded nanowires or nanocrystals of the metal oxides and the membrane, so as to enable lithium-sulfur batteries with high energy density and prolonged cycling life. The invention also relates to a lithium-sulfur battery that contains the RSL.
