Synthesis and characterization of electrospun molybdenum dioxide-carbon nanofibers as sulfur matrix additives for rechargeable lithium-sulfur battery applications.

ABSTRACT: One-dimensional molybdenum dioxide-carbon nanofibers (MoO₂-CNFs) were prepared using an electrospinning technique followed by calcination, using sol-gel precursors and polyacrylonitrile (PAN) as a processing aid. The resulting samples were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, Brunauer-Emmet-Teller (BET) surface area measurements, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). MoO₂-CNFs with an average diameter of 425-575 nm obtained after heat treatment were used as a matrix to prepare sulfur/MoO₂-CNF cathodes for lithium-sulfur (Li-S) batteries. The polysulfide adsorption and electrochemical performance tests demonstrated that MoO₂-CNFs did n
