A new type of nitrogen‐enriched carbon materials is synthesized from nitrile‐rich alkali salts. High nitrogen content is obtained for these alkali salts precursors after annealing at 850 °C. These nitrogen‐enriched carbons exhibit high coulombic efficiency, high reversible capacity and good cycling stability as anode materials for both mature lithium ion batteries and newly rejuvenated sodium ion batteries.
