A High‐Volumetric‐Capacity Cathode Based on Interconnected Close‐Packed N‐Doped Porous Carbon Nanospheres for Long‐Life Lithium–Sulfur Batteries

This study reports a Li–S battery cathode of high volumetric capacity enabled by novel micro‐ and mesostructuring. The cathode is based on monodisperse highly porous carbon nanospheres derived from a facile template‐ and surfactant‐free method. At the mesoscale, the nanospheres structure into interconnected close‐packed clusters of a few microns in extent, thus facilitating the fabrication of dense crack‐free high areal sulfur loading (5 mg cm...
