We succeed in obtaining Mo2C embedded in S-doped carbon (Mo2C/SC) nanofibers by electrospinning and sulfuration. The use of S-doped carbon not only provides more additional Na+ storage active sites to enhance its sodium storage performance, but also increases electrons migration and ions diffusion. As the anodes for sodium ion batteries (SIBs), the electrode exhibits excellent rate capacities of 242 and 96 mA h g(-1) from 0.1 A g(-1) to 5 A g(-1). Excitingly, the high-rate performance is superior, achieving 102.7 rnA h g(-1) at 5 A g(-1) over 1000th cycle. This project provides ideas for the development the high-rate and long-term stable of the Mo2C in energy storage devices.
