Zusammenfassung:	Li‐O2 Batteries In article number 2303055, Wei Yu, Hirotomo Nishihara and co‐workers design a free‐standing graphene mesosponge sheet (GMS‐sheet) as a carbon cathode for high‐performance Li‐O2 batteries. The hierarchically porous GMS‐sheet ensures a large loading of Li2O2 toroids and contributes to a high areal capacity (>30.0 mAh cm−2) and long cycle stability (>260 cycles) at a current density of 0.4 mAh cm−2.
