In situ-formed porous carbon nanofibers were synthesized by electrospinning with a volatile solvent additive into an ice water bath.
Porous carbon nanofibers assembled with a nickel nanoparticle (Ni/PCNFO) cathode exhibited outstanding electrochemical performance in Li–S batteries.
Among the emerging energy storage methods, lithium–sulfur (LIS) batteries have drawn plenty of attention due to their high theoretical energy density, low cost and environmental benignity.
