3D Graphene‐Foam–Reduced‐Graphene‐Oxide Hybrid Nested Hierarchical Networks for High‐Performance Li–S Batteries

A 3D graphene-foam–reduced-graphene-oxide hybrid nested hierarchical network is synthesized to achieve high sulfur loading and content simultaneously, which solves the "double low" issues of Li–S batteries. The obtained Li–S cathodes show a high areal capacity two times larger than that of commercial lithium-ion batteries, and a good cycling performance comparable to those at low sulfur loading.
