• coefficient, low interfacial resistance and much better electrochemical performance than pristine sulfur cathodes. Keywords: electrochemical performance; electrospinning; lithium–sulfur batteries; MoO2–CNFs; sulfur matrix; Introduction Lithium–sulfur (Li–S) batteries are considered to be the most promising

• nanofibers have extremely high specific surface area because of their small diameter and their porosity which exhibits excellent pore interconnectivity [25][26]. To the best of our knowledge, no articles related to using MoO2–CNFs as a sulfur matrix in Li–S batteries have been published so far. In the

• sulfur cathode, the cathode performance clearly improved when MoO2–CNFs were present in the sulfur matrix. The initial discharge capacity of the S/MoO2–CNF cathodes with MoO2–CNFs calcined at 550, 650, 750, and 850 °C were recorded as 816, 1082, 1079, and 1095 mAh g−1, respectively. The improved
