A polyacrylonitrile (PAN) nanofiber web was prepared by electrospinning PAN solutions with dimethyl sulfoxide (DMSO) or Dimethylformamide (DMF) as solvent. The PAN web was heated with sulfur to synthesize a sulfurized polyacrylonitrile (SPAN) nanofiber web. The shape of the SPAN web was found to depend on concentration of the PAN solution and properties of the solvent. The SPAN web synthesized using 8 wt% PAN solution in DMSO showed the highest capacity of 1053.3 mAh g(sulfur)(-1) under a current density of 526 mA g(sulfur)(-1). Thus, we determined that DMSO could be a potential solvent for preparation of SPAN web electrodes.
