Abstract

We report the performance of a series of hierarchical porous carbons (HPCs) with extremely high surface areas of up to 2340 m2 g-1 with total pore volume of up to 3.8 cm3 g-1 as supports for sulfur for Li-S batteries. The hierarchical structure of the carbon originating from interconnected large mesopores (10-50 nm), small mesopores (2-10 nm) and micropores (
