Abstract

Superior cathode material: Spherical ordered mesoporous carbon nanoparticles featuring very high inner porosity (pore volume of 2.32 cm3 g−1 and surface area of 2445 m2 g−1) were synthesized in a two-step casting process. They were successfully applied as cathode material in Li-S batteries, where they showed high reversible capacity up to 1200 mA h g−1 and excellent cycling efficiency.
