1 Introduction. Sulfur (S 8) is an attractive electrode material with low cost and excellent ability to store lithium (1675 mAh g −1); hence the great potential for use in electric vehicles and grid-level energy storage. [1-3] However, an inherent problem of sulfur electrode is the sluggish reaction kinetics associated with the complex polysulfides (LiPS) transformations and multistep ...
