Abstract

With milling time up to 6 h combined XRD patterns and DSC show α Fe as well as some amorphous selenium For the samples milled between 10 h and 20 h the orthorhombic FeSe 2 and β FeSe hexagonal nanometric phases are formed and the volume fraction of the α Fe phase decreases



Sulfur Impregnated Disordered Carbon Nanotubes

The commercialization of lithium–sulfur batteries is hindered by low cycle stability and low efficiency which are induced by sulfur active material loss and polysulfide shuttle reaction through dissolution into electrolyte In this study sulfur impregnated disordered carbon nanotubes are synthesized as cathode material for the lithium–sulfur battery The obtained sulfur–carbon tube
