A Mixed Microporous/Low-range Mesoporous Composite with High Sulfur Loading from Hierarchically-structured Carbon for Lithium Sulfur Batteries

Abstract N-doped hierarchical porous carbon was prepared by the carbonization of a polypyrrole precursor and activated using potassium hydroxide. The resulting carbon material has a specific area as high as 3271 m 2  g −1 and a hierarchical porous structure consisting of mixed parts microporous (
