All-in-One Sulfur Host: Smart Controls of Architecture and Composition for Accelerated Liquid–Solid Redox Conversion in Lithium–Sulfur Batteries

The development of Li–S batteries (LSBs) is largely impeded by sluggish redox kinetics and notorious polysulfide shuttling. Herein, hierarchical MoC@Ni–NCNT arrays are reported as a multifunctional sulfur host in Li–S batteries, which comprised a flexible carbon fiber cloth substrate decorated with vertical MoC porous nanorods rooted by interconnected nitrogen-doped carbon nanotubes (NCNTs). In the designed host, the inner MoC porous backbone...
