Sodium-ion batteries have attracted much attention in recent years due to the abundance of resources and cost, but the development of higher-performance anode materials is essential to improve their performance. In this study, we focused on Expanded Graphite, in which the interlayer of graphite is expanded. To further improve the performance, nitrogen-doped Expanded Graphite was prepared, and evaluated and analyzed by XPS and Raman spectroscopy.
