Bifunctional semi-closed YF3-doped 1D carbon nanofibers with 3D porous network structure including fluorinating interphases and polysulfide confinement for lithium–sulfur batteries

In this study, semi-closed YF₃-doped 1D carbon nanofibers with 3D porous networks (SC-YF₃-doped 3D in 1D CNFs) are fabricated for the first time via electro-blown spinning technology and regarded as cathodes for high performance lithium sulfur cells.
