Turning stone into gold : The cover image depicts a green and efficient route to convert spent sulfidic caustic (SSC) into advanced energy‐storage materials. Compared with the conventional methods to transform sulfide separately, the novel strategy to recycle sulfide from SSC is particularly striking, not only decreasing the polluting sulfide successfully, but also simultaneously fabricating a sulfur/carbon composite for lithium–sulfur batteries. The composite with the appropriate inner/external ratio of sulfur content exhibited excellent areal capacity and good cycling performance. These excellent results prove the feasibility of an innovative method of “pollutant disposal with synchronization application”, which integrates environmental management with storage‐energy‐material development efficiently, replacing the tedious methods of disposing of pollutant and preparing the slurry‐derived sulfur cathode individually. More details can be found in the Full Paper by Wenlong Huang and Zhongqiang Shan et al. from Tianjin(Peiyang) University of China on page 1282 in Issue 8, 2017 (DOI: 10.1002/ente.201600611).
