In article number 1903712, Sangbaek Park, Dong‐Wan Kim, and co‐workers develop a dual hollow scaffold where micro‐hollows consisting of CoS 2 nanoparticles wrapped in N‐doped graphitic carbon nanoshells creates a macro‐hollow as an efficient sulfur host via in situ and template‐free formation based on metal‐organic‐framework chemistry. The unusual multiple porosity in a carbon scaffold with the presence of CoS 2 allows high‐sulfur loading and superior lithium storage performances.
