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.
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.
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.
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 .
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.
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.
