The fabrication of large‐area free‐standing porous nitrogen‐doped carbon nanofiber films is reported. The flexible film exhibits a high rate capability and ultralong cycle life used for sodium‐ion batteries, due to the presence of abundant pores, high nitrogen‐doping level, interconnected conductive network, and excellent structural stability of the electrode.
