Hierarchically structured (Co1/3Fe2/3)Se2nanofibers with fiber-in-tube nanostructures were prepared by an electrospinning process and subsequent selenization. The synergetic effects of the hierarchical structures and ultrafine nanorods with high electrical conductivity resulted in superior rate performance of the hierarchically structured (Co1/3Fe2/3)Se2nanofibers.

Owing to the speculated price hike and scarcity of lithium resources, sodium-ion batteries are attracting significant research interest these days. However, sodium-ion battery anodes do not deliver good electrochemical performance, particularly rate performance. Herein, we report the facile electrospinning synthesis of a free-standing nickel disulfide (NiS2) embedded on carbon nanofiber. This electrode did not require a conducting agent, current collector, and binder, and typically delivered high capacity and rate performance. The electrode delivered a high initial capacity of 603 mAh g−1 at the current density of 500 mA g−1. Moreover, the electrode delivered the capacity of 271 mAh g−1 at the high current density of 15 A g−1. The excellent rate performance and high coulombic efficiency of the electrode were attributed to its low charge transfer resistance and unique structure.
