The nitrogen-sulfur co-doped FeS/C nanofibers (N, S-FeS/C) have been prepared by electrospinning followed by carbonization and sulfuration at high temperature. At the same time, the effect of sulfuration temperature on the lithium and potassium storage properties of N, S-FeS/C are investigated. The N, S co-doped carbon layer can suppress the agglomeration and volume expansion of FeS particles during the charge–discharge process, coupled with good electronic conductivity of carbon matrix and good crystallinity of FeS particles at optimized sulfuration temperature. And the N, S-FeS/C obtained by sulfuration at 600 °C exhibits outstanding electrochemical performance in lithium-ion batteries (LIBs) and potassium-ion batteries (PIBs), which shows high reversible capacities of 653 mAh g−1 at 1000 mA g−1 after 250 cycles in LIBs and 270 mAh g−1 after 190 cycles at 20 mA g−1 in PIBs. The N, S-FeS/C are promising anode materials for both LIBs and PIBs that could be demonstrated.
