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. Due to the high operating temperature required (usually between 300 and 350 °C), as well as the highly reactive nature of sodium and. ConstructionTypical batteries have a solid membrane between the and , compared with liquid-metal batteries. .
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). .
Pure presents a hazard, because it spontaneously burns in contact with air and moisture, thus safety features are required to avoid direct contact with water and oxidizing atmospheres. Early on th. .
pioneered the in the 1960s to power early-model . In 1989 resumed its work on a Na-S battery powered electric car, which was named . The car had a 100-mile dri. .
NaS batteries can be deployed to support the electric grid, or for stand-alone renewable power applications. Under some market conditions, NaS batteries provide value via energy (charging battery when electr.
