A sodium–sulfur (NaS) battery is a type of molten-salt battery that uses liquid sodium and liquid sulfur electrodes. [1] [2] This type of battery has a similar energy density to lithium-ion batteries, [3] and is fabricated from inexpensive and non-toxic materials.
Sodium-ion batteries (NIBs, SIBs, or Na-ion batteries) are several types of rechargeable batteries, which use sodium ions (Na +) as its charge carriers. In some cases, its working principle and cell construction are similar to those of lithium-ion battery (LIB) types, but it replaces lithium with sodium as the intercalating ion .
Sodium sulfate (also known as sodium sulphate or sulfate of soda) is the inorganic compound with formula Na 2 SO 4 as well as several related hydrates. All forms are white solids that are highly soluble in water.
The lithium–sulfur battery (Li–S battery) is a type of rechargeable battery. It is notable for its high specific energy. The low atomic weight of lithium and moderate atomic weight of sulfur means that Li–S batteries are relatively light (about the density of water).
The sodium–sulfur battery is formed by combining the liquid states of the negative sodium and positive sulfur electrodes. Both electrode components are in a liquid state. It has been developed to provide the energy and power density required for electric vehicles.
The sodium-sulfur battery (Na–S) combines a negative electrode of molten sodium, liquid sulfur at the positive electrode, and β-alumina, a sodium-ion conductor, as the electrolyte to produce 2 V at 320 °C. This secondary battery has been used for buffering solar and wind energy to mitigate electric grid fluctuations.
