The Front Cover Image shows the artistic representation of sulfur nanoparticle formation and graphene surface functionalization through Vitamin C treatment, which improves the performance of next‐generation lithium–sulfur batteries for electric vehicles. Vitamin C—a low‐cost and eco‐friendly substance—simultaneously allows the synthesis of uniformly sized sulfur nanoparticles in the range of tens of nanometers and facilitates controlled oxygen functionalization of graphene. A dual‐layered cathode‐based lithium–sulfur battery is then assembled using the Vitamin C‐reduced graphene oxide in the cathode and as an interlayer. This strategy leads to a high specific capacity and stable performance of the battery even under high current densities. More details can be found in the Full Paper by J. Lee et al. on page 2883 in Issue 17, 2015 . (DOI: 10.1002/cssc.201500111 ).
