Batteries: 3D Mesoporous Graphene: CVD Self-Assembly on Porous Oxide Templates and Applications in High-Stable Li-S Batteries (Small 39/2015)

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 cm3 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.
