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.
