Lithium–sulfur batteries (Li–S) are recognized as the next generation of secondary batteries due to their satisfactory theoretical specific capacity and energy density. However, a series of problems such as disordered migration behavior, sluggish redox kinetics, and serious shuttle effect of lithium...
