Lithium‐Sulfur Batteries: “Brain‐Coral‐Like” Mesoporous Hollow CoS 2 @N‐Doped Graphitic Carbon Nanoshells as Efficient Sulfur Reservoirs for Lithium–Sulfur Batteries (Adv. Funct. Mater. 38/2019)

In article number 1903712, Sangbaek Park, Dong-Wan Kim, and co-workers develop a dual hollow scaffold where micro-hollows consisting of CoS2 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 CoS2 allows high-sulfur loading and superior lithium storage performances.
