Porous graphene frameworks (PGFs) are fabricated by Q. Zhang and co‐workers on hierarchically mesoporous oxide templates, with small pores induced by Kirkendall diffusion, and large pores attributed to the evaporation of a deliberately introduced volatile metal. On page 5243, PGFs with very high mesopore volumes of 2.40 cm 3 g −1 are shown to serve as reservoirs of ions or active materials in lithium–sulfur battery applications. A very high sulfur utilization and a very low fading rate are achieved.
