The Cover Feature illustrates the extraordinary volume expansion for an ultrahigh areal capacity holey graphene (grey colored)‐based composite air cathode, with intact graphene (green colored) as an additive, after capturing gaseous oxygen molecules during discharge to form a large amount of toroid‐like Li 2 O 2 particles (gold colored) within the scaffold.
