Conversion mechanism of sulfur in room-temperature sodium-sulfur

In an effort to clarify this puzzling process, two primary models have been reported. On the one hand, a model involving small sulfur molecules (S 2–4) within a microporous carbon host (∼0.5 nm in diameter) was proposed to account for the single or double voltage platforms observed in the discharge and charge curves [4, 24].Although this proposition aligns

For operation, the entire battery must be heated to, or above, the melting point of sulfur at 119 °C. Sodium has a lower melting point, around 98 °C, so a battery that holds molten sulfur holds molten sodium by default. This presents a serious safety concern; sodium can spontaneously ignite in air, and sulfur is highly flammable.
