Remedies for Polysulfide Dissolution in Room‐Temperature Sodium–Sulfur Batteries

Rechargeable room‐temperature sodium–sulfur (RT‐NaS) batteries represent one of the most attractive technologies for future stationary energy storage due to their high energy density and low cost. The S cathodes can react with Na ions via two‐electron conversion reactions, thus achieving ultrahigh theoretical capacity (1672 mAh g −1 ) and specific energy (1273 Wh kg −1 ). Unfortunately, the sluggish reaction kinetics of the nonconductive S,...
