A new synthesis methodology for carbon quantum dots (CQDs) for large‐scale production is proposed for the first time by X. Ji and co‐workers on page 7861. The as‐obtained CQDs can be transformed into 3D porous carbon frameworks exhibiting superb sodium storage properties with an ultralong cyclelife and ultrahigh rate capability, which are comparable to state‐of‐the‐art carbon anode materials for sodium‐ion batteries.
