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.
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.
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 .
The sodium–sulfur battery uses sulfur combined with sodium to reversibly charge and discharge, using sodium ions layered in aluminum oxide within the battery's core. The battery shows potential to store lots of energy in small space.
Early work on the sodium sulfur battery took place at the Ford Motor Co in the 1960s but modern sodium sulfur technology was developed in Japan by the Tokyo Electric Power Co, in collaboration with NGK insulators and it is these two companies that have commercialized the technology. Typical units have a rated power output of 50 kW and 400 kWh.
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.
