Structure of sodium–sulfur battery . Sodium β′′-Alumina (beta double-prime alumina) is a fast ion conductor material and is used as a separator in several types of molten salt electrochemical cells. The primary disadvantage is the requirement for thermal management, which is necessary to maintain the ceramic separator and cell seal integrity.
At 350 °C, the specific energy density of the battery reached 760 Wh/kg, which is approximately three times that of a lead-acid battery. As a result, sodium-sulfur batteries require approximately one-third of the area needed for lead-acid batteries in identical commercial applications .
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.
Sodium sulfur batteries have gained popularity because of the wide availability of sodium and its stable operation in all temperature levels. They act as a reliable element of storage technology due to their high value of specific energy density and are comparatively cheaper than the other storage devices.

A sodium–sulfur battery is a secondary battery operating with molten sulfur and molten sodium as rechargeable electrodes and with a solid, sodium ion-conducting oxide (beta alumina β″-Al2O3) as an electrolyte.
The typical sodium sulfur battery consists of a negative molten sodium electrode and an also molten sulfur positive electrode. The two are separated by a layer of beta alumina ceramic electrolyte that primarily only allows sodium ions through. The charge and discharge process can be described by the chemical equation,
