Abstract

The electrochemical performance of sodium-ion battery (SIB), which is considered to have high potential to replace the lithium-ion battery, in cycling stability at large current density needs to be improved. Herein, a hybrid of antimony nanoparticles and nitrogen-doped hollow porous hard carbon nanofiber (Sb/N-HPCNF) is synthesized through electrospinning and in situ replacement. As an anode of SIB, Sb/N-HPCNF presents excellent cycling stability (281 mAh g−1 after 2000 cycles at 2 A g−1). Such a performance mainly stems from the hollow porous structure, which promotes the electrolyte diffusion along the pores and provides more active sites for Na+ insertion/extraction. This work provides an ingenious strategy for constructing well-designed structures for advanced energy storage technology.
