Abstract Room‐temperature sodium–sulfur (RT‐Na/S) batteries are emerging as promising candidates for stationary energy‐storage systems, due to their high energy density, resource abundance, and environmental benignity. A better understanding of RT‐Na/S in the view whole battery components is essential importance fundamental research practical applications. In particular, other than sulfur cathodes preventing migration polysulfides accelerating reaction kinetics have been greatly overlooked. Such a biased trend also adverse broader applications batteries, which long ignored previous reviews. Herein, approaches historical progress toward through “teamwork” perspective comprehensively summarized, balanced trends encouraged enable batteries. meantime, persisting issues, solutions, advanced host design, Na metal anode protection, electrolyte optimization, separator modification, binder engineering clearly emphasized. Finally, device‐scale evaluation parameters characterization tools thoroughly provided. This review aims provide on whole‐cell design guidelines that can shed light directions
