Commercial 3,4,9,10‐perylene‐tetracarboxylicacid‐dianhydride (PTCDA) without modification shows promising performance as a cathode for sodium‐ion batteries. It exhibits a high reversible capacity of 145 mAh g −1 , a rate capability of 91 mAh g −1 at 1000 mA g −1 , and a stable cycle life. When discharged to 0.01 V, 15 sodium ions can be incorporated into a PTCDA, exhibiting an extremely high capacity of 1017 mAh g −1 .
