Lithium–sulfur batteries (LSBs) are cost‐effective and high‐energy‐density batteries. However, the insulating nature of active materials, the shuttle effect, and slow redox kinetics lead to severe capacity decay and low rate capabilities. Numerous multimodal approaches have been attempted to tackle these issues and have pushed the cycle stability and energy density to higher levels. Recently, accelerating the redox kinetics using catalytic materials has been considered as a means to realize high‐performance LSBs. In this Minireview, we provide an insightful overview of the advances in the design of LSB catalytic materials and mechanistic descriptions of their catalytic activities.
