Sn nanoparticles@nitrogen-doped carbon nanofiber composites as high-performance anodes for sodium-ion batteries

Abstract

Sn nanoparticles on nitrogen doped carbon nanofibers (Sn@NCNFs) composites have been synthesized by electrostatic spinning technique and used as the anode of sodium-ion batteries (SIBs) with the capacity of 390 mA h g⁻¹ at 1 C for over 1000 cycles.
