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, severe...
