A new methodology for the synthesis of carbon quantum dots (CQDs) for large production is proposed. The as‐obtained CQDs can be transformed into 3D porous carbon frameworks exhibiting superb sodium storage properties with ultralong cycle life and ultrahigh rate capability, comparable to state‐of‐the‐art carbon anode materials for sodium‐ion batteries.
