Polyaniline-Derived Carbon Heterostructure as Redox Mediator of Li2S Oxidation and Polysulfide Immobilizer for High-Performance Lithium–Sulfur Cathode

The merit of high energy density endows the lithium sulfide (Li2S)-based lithium–sulfur batteries (LSBs) as a promising candidate for next-generation energy storage batteries. In this work, Li2S is...
