The growing demands on high-performance energy-storage system for emerging technologies such as electric vehicles and artificial intelligence drive the development of high-performance batteries. As a promising candidate of next-generation batteries, Li-S batteries have been drawn much attention carrying a high specific capacity (1675 mAh g-1) and energy density (2600 Wh kg-1). However, the diffusion of polysulfide in electrolytes cause changes in the structure of the sulfur cathode during discharge-charge cycles, which greatly limits the commercial applications of Li-S batteries.
