ABSTRACT
Sb–C nanofibers are synthesized successfully through a single-nozzle electrospinning technique and subsequent calcination. The structural morphological characterizations reveal the uniform nanofiber structure with Sb nanoparticles embedded homogeneously in carbon nanofibers. Electrochemical experiments show that electrode can deliver large reversible capacity (631 mA h g−1) at C/15, greatly improved rate capability (337 g−1 5 C) excellent cycling stability (90% retention after 400 cycles). superior electrochemical performances of due to unique distribution matrix, which provides conductive buffering matrix for effective release mechanical stress caused by Na ion insertion/extraction prevent aggregation nanoparticles.
