Which positive electrodes are used in sodium-sulfur batteries?

The sulfur-carbonaceous composite positive electrodes are the widely used positive electrodes in sodium-sulfur batteries. The different carbonaceous matrices have different advantages. The macropores can make sure the excellent contact between electrolytes and active materials. The micropores are easily fixed with active materials.

Can sulfur be used as a negative electrode?

Great advantages of sulfur as negative electrode are its high theoretical capacity (1672 mAh g −1) [ 6 ], low price (0.09 USD kg −1) [ 18] and potential sustainability (sulfur is a waste product of the petrochemical industry [ 19 ]). Furthermore, reductively less stable electrolytes including concentrated aqueous ones can be used [ 11, 15 ].

What are sodium sulfur batteries?

Sodium sulfur (NaS) batteries are a type of molten salt electrical energy storage device. Currently the third most installed type of energy storage system in the world with a total of 316 MW worldwide, there are an additional 606 MW (or 3636 MWh) worth of projects in planning. They are named for their constituents: Sodium (Na) and Sulfur (S).

Can a sodium sulfur battery be used outside of testing?

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.

What are the advantages of a sodium sulfur battery?

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. Their cost per capacity is in the middle compared to other options.

What electrolyte does a sodium chloride battery use?

Sodium–metal chloride batteries also use a β″-alumina electrolyte in direct contact with the molten sodium active mass. However, the metal chloride electrode is immersed in a molten salt electrolyte such as sodium chloroaluminate (NaAlCl 4).
