Lithium–Sulfur Batteries: Metallic MoS2 Nanoflowers Decorated Graphene Nanosheet Catalytically Boosts the Volumetric Capacity and Cycle Life of Lithium–Sulfur Batteries (Adv. Energy Mater. 12/2021)

In article number 2003718 Zhibin Cheng, Zhangjing Zhang and co-workers systematically modify lithium–sulfur batteries through coating metallic MoS2 nanoflower-decorated graphene (FM@G) on both a commercial polypropylene separator and a sulfur cathode. The unique flower-like 1T-MoS2 in the FM@G nanosheet allows more accessible catalytic active sites and speedy electron transfer, resulting in synergy effects between the sulfur host and the separator coating in suppressing shuttle effects and propelling catalytic conversion of polysulfides.
