Abstract:Transition metal sulfides (TMSs) are considered as promising anode materials for sodium-ion batteries (SIBs) due to their high theoretical capacities. However, the relatively low electrical conductivity, large volume variation, and easy aggregation/pulverization of active materials seriously hinder their practical application. Herein, okra-like NiS 2 /FeS 2 particles encapsulated in multichannel Ndoped carbon nanofibers (NiS 2 /FeS 2 @MCNFs) are fabricated by a coprecipitation, electrospinning, and carbonizati… Show more
