Vertically Aligned MoS2/MXene Heterojunction as a Bifunctional Separator Coating for Suppressing Shuttle Effect and Enhancing Li+ Transport in Li-S Batteries.
Lithium-sulfur batteries are considered one of the most promising next-generation energy storage systems owing to their high theoretical energy density and natural abundance of sulfur. However, their practical application is severely hampered by the polysulfide shuttle effect and sluggish conversion kinetics. Herein, a...
