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.
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.
This paper presents a review of the state of technology of sodium-sulfur batteries suitable for application in energy storage requirements such as load leveling; emergency power supplies and uninterruptible power supply. The review focuses on the progress, prospects and challenges of sodium-sulfur batteries operating at high temperature (~ 300 °C).
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.
However, no official source can be found stating operational use of this battery outside of testing. 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.
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.
