摘要：
Superior cathode material: Spherical ordered mesoporous carbon nanoparticles featuring very high inner porosity (pore volume of 2.32 cm 3 g -1 and surface area of 2445 m 2 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. © 2012 Wiley-VCH Verlag GmbH & Co.
