Abstract:

Hollow carbon nanofiber was selected as the conductive matrix for elemental sulfur. The influences of preparation method and sulfur content on the structure and properties of the composite were investigated. It is found that the treatment process is inclined to produce large-sized sulfur particles accompanied by severe agglomeration. On the contrary, uniform distribution and compact contact can be established between sulfur and carbon for the composite based on liquid phase precipitation and appropriate sulfur content. The hollow nanofiber material with superior conductivity, abundant holes and good mechanical property, constructs a highly-conductive, porous and stable three-dimensional framework, promoting the electrochemical performances of lithium sulfur batteries.
