Abstract Lithium−sulfur (Li−S) batteries have attracted particular interest as promising next‐generation energy storage devices because of their high theoretical density and low cost. The real performance Li−S is, however, far from achieving the expected values, even when using a porous, highly conductive host sulfurs to improve electric conductivity accommodate volume changes. restrictions are mainly attributable slow reaction kinetics converting lithium polysulfides species sulfide elemental sulfur during charging discharging processes, respectively. Recent studies show that single‐atom catalysts (SACs) with superior catalytic activity offer an effective strategy for solving this tough issue. recent advances in utilizing SACs batteries, which involve catalyst preparation, battery performance, mechanistic insights, summarized here. Modification cathodes separators helps absorb polysulfide promote conversion kinetics, thus suppressing notorious “shuttle effect.” In addition, introduction into promotes efficiency Li stripping/plating prevents growth dendrites. Overall, boost effects SAC on noticeable deserving more research attention develop better batteries.
