4 FAQs about Is sodium-sulfur battery a flow battery

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.

How does a sodium sulfide battery work?

In a sodium sulfide battery, molten sulfur is used as the cathode and molten sodium is used as the anode. The electrolyte is a solid ceramic-based electrolyte called sodium alumina. When the battery is discharged each sodium atom gives away one electron forming sodium ions. The electrons take the external circuitry to reach the positive terminal.

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.

What are molten sulfur and sodium batteries used for?

Molten sulfur and molten sodium are used as the electrode materials for the sodium-sulfur batteries. This kind of battery operates at higher temperatures ranging from 300°C to 350°C. An internal machine is employed for heating purposes to provide the required active temperatures in the system. The electrodes are separated by a ceramic layer.
