Sandwiching Sulfur into the Dents Between N, O Co-Doped Graphene Layered Blocks with Strong Physicochemical Confinements for Stable and High-Rate Li–S Batteries

Highlights N, O co-doped graphene layered block (NOGB) was prepared as sulfur host for lithium–sulfur batteries. The NOGB/S shows good rate performance due to robust electrochemical kinetics. The strong physicochemical confinement leads to an improved cycling stability.
