Nitrogen Doped Carbon Nanofiber Composites as Anode for Sodium-Ion Batteries — •Mo Sha, Long Liu, Huaping Zhao, and Yong Lei — Institut für Physik & IMN MacroNano (ZIK), Technische Universität Ilmenau, 98693, Ilmenau, Germany

Recently, sodium-ion batteries (SIBs) have attracted increasing attention as an important supplement or alternative to lithium ion batteries (LIBs) due to the abundance of sodium resources and its much lower cost. A critical issue and great challenge in current battery research for the extensive application of SIBs is the development of earth-abundant and high-performance electrode materials. In various studies of these electrode materials, carbon nanofibers have been identified as promising anodes for SIBs, because of the low cost and environment friendly features. In this study, nitrogen-doped carbon nanofiber (NCNFs) have been synthesized by an electrostatic spinning technique and used as anodes for SIBs. The corresponding specific capacity can reach about 175 mA h g-1 at 0.1C after 100 cycles. The results demonstrate that this NCNFs composite is a promising anode material with good reversible capacity and cycling performance for SIBs.
