What is a sodium sulfur battery?

A sodium–sulfur (NaS) battery is a type of molten-salt battery that uses liquid sodium and liquid sulfur electrodes. This type of battery has a similar energy density to lithium-ion batteries, and is fabricated from inexpensive and low-toxicity materials.

📌

What is a sodium polysulfide battery?

Due to the high operating temperature required (usually between 300 and 350 °C), as well as the highly reactive nature of sodium and sodium polysulfides, these batteries are primarily suited for stationary energy storage applications, rather than for use in vehicles.

📌

Do all aqueous batteries use sulfur?

Whereas nonaqueous lithium-sulfur 4, 5, 6 and high-temperature sodium-sulfur batteries 7 use sulfur as the cathode, an all-aqueous system must use sulfur as the anode material to preserve aqueous stability while reaching a meaningful cell voltage.

📌

Which chemistry is used in air-breathing aqueous sulfur flow battery approach?

Curves for the present air-breathing aqueous sulfur flow battery approach using Na and Li chemistry are shown in green and gray, respectively. The chemical costs for Na and Li are shown as dashed lines.

📌

How much does a sodium-polysulfide battery cost?

For sodium-polysulfide chemistry, the chemical cost is remarkably low, only US$0.4–1.7/kWh (using acidic catholyte at 5 M S), depending on the utilization of sulfur theoretical capacity (100%–25%). At 50% utilization or higher, one reaches the lowest chemical cost to our knowledge of any rechargeable battery (Figure 1).

📌

Can a aqueous polysulfide flow battery meet future energy storage needs?

In this work, we demonstrate an ambient-temperature, air-breathing, aqueous polysulfide flow battery that exploits sulfur's intrinsic advantages, and show using techno-economic analyses that such an approach has the potential to meet future storage needs for renewable energy.
