Due to the high operating temperature required (usually between 300 and 350 °C), as well as the highly reactive nature of sodium and sodium polysulfides, these batteries are primarily suited for stationary energy storage applications, rather than for use in vehicles.OverviewA sodium–sulfur (NaS) battery is a type of that uses liquid and liquid . This type of battery has a similar to , and is fabricated from inexpensive and. .
Typical batteries have a solid membrane between the and , compared with liquid-metal batteries where the anode, the cathode and the membrane are liquids. The. .
During the discharge phase, sodium at the core serves as the , meaning that the donates electrons to the external circuit. The sodium is separated by a (BASE).
