Hierarchical Li 2 S–carbon‐nanocomposite particles are synthesized by G. Yushin and co‐workers, as described on page 5579, using a simple solution‐based method followed by vapor deposition. The multiscale and multilevel protection enabled by the proposed architecture prevents mechanical degradation and polysulfide dissolution in lithium–sulfur batteries. The proposed hierarchical particle–shell design can be effectively utilized for a variety of other conversion‐type cathode materials.
