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.
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.
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.
Lifetime is claimed to be 15 year or 4500 cycles and the efficiency is around 85%. Sodium sulfur batteries have one of the fastest response times, with a startup speed of 1 ms. The sodium sulfur battery has a high energy density and long cycle life. There are programmes underway to develop lower temperature sodium sulfur batteries.
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 .
One advantage of a sodium sulfur battery is that it is a mature system with established experience and presence on the market. Since their container is entirely sealed while in operation, they are environmentally friendly. Their cost per capacity is in the middle compared to other options.
