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.
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.
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.
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.
