The porous structure of a Co‐Al‐LDH–graphene–layered MnO 2 nanohybrid is compared with the agglomerated structure of MnO 2 ‐free‐Co‐Al–LDH–graphene by S.‐J. Hwang and co‐workers. On page 3921, the Co‐Al‐LDH–graphene–layered MnO 2 nanohybrid shows a porous morphology formed by the house‐of‐cards‐type stacking of sheet‐like crystallites. The incorporation of the MnO 2 nanosheets provides more sites for the intercalation of potassium ions and also creates more open sites by preventing the agglomeration of rGO nanosheets.
