Abstract The lithium–sulfur (Li–S) battery is widely regarded as a promising energy storage device due to its low price and the high earth‐abundance of materials employed. However, shuttle effect lithium polysulfides (LiPSs) sluggish redox conversion result in inefficient sulfur utilization, power density, rapid electrode deterioration.
