Hollow carbon nanofibers as high-performance anode materials for sodium-ion batteries

Author affiliations

Abstract

Hollow carbon nanofibers (HCNFs) are successfully fabricated by pyrolyzation of a polyaniline hollow nanofiber precursor. The as-prepared HCNFs as sodium storage anode materials exhibit a high reversible charge capacity of 326 mA h g−1 at 20 mA g−1, high rate capability (85 mA h g−1 at 1.6 A g−1) and superior cycling stability (a capacity retention of 70% even after 5000 cycles at 1.6 A g−1). Such a high performance of HCNFs can be ascribed to the special hollow structure characteristics; they possess a well fabricated electronic transport path and can shorten the ion diffusion distance. Therefore, the HCNFs can be regarded as promising anode materials for advanced sodium ion batteries (SIBs).
