摘要：

Slowing down the shuttle: C@S nanocomposites (see TEM images) based on mesoporous, hollow carbon capsules were generated by a template-based approach. As the cathode material in a Li-S secondary battery, they display outstanding electrochemical features attributed to sequestration of elemental sulfur in the carbon capsules and to its favorable effect in limiting polysulfide shuttling as well as to enhanced electron transport from the sulfur. © 2011 WILEY-VCH Verlag GmbH & Co.
