Abstract

Going into their shell: A novel carbon-sulfur nanocomposite has been synthesized by confining sulfur in double-shelled "soft" carbon hollow spheres (see figure) with high surface area and porosity. This carbon-sulfur nanocomposite shows outstanding electrochemical performance when evaluated as a cathode material for lithium-sulfur batteries. Copyright © 2012 WILEY-VCH Verlag GmbH & Co.
