Solar Cells: Facile Synthesis of Crumpled Nitrogen‐Doped MXene Nanosheets as a New Sulfur Host for Lithium–Sulfur Batteries (Adv. Energy Mater. 13/2018)

In article number 1702485 Dan Wang and Guoxiu Wang and co-workers design a novel strategy for doping heteroatomic nitrogen into MXene frameworks. The resultant nitrogen-doped MXene nanosheets demonstrate a well-defined porous structure, a high surface area and large pore volume. The nitrogen-doped porous MXene nanosheets are successfully used for strong physical and chemical co-absorption of polysulfides. Lithium-sulfur batteries, based on porous N-doped MXene nanosheets/sulfur composites, exhibit an outstanding electrochemical performance.
