A new application of graphene quantum dots (GQDs) as an ideal electrode material for supercapacitors is explored by X.‐B. Yan and co‐workers. On page 4111 they build a GQD//GQD symmetric micro‐supercapacitor and a GQD//MnO 2 asymmetric supercapacitor. Both devices show excellent rate capabilities, exceptionally high‐frequency responses, and long‐term cycle stability.
