6 FAQs about [Understand sodium-sulfur battery in one picture]

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).

How does a sodium sulfide battery work?

In a sodium sulfide battery, molten sulfur is used as the cathode and molten sodium is used as the anode. The electrolyte is a solid ceramic-based electrolyte called sodium alumina. When the battery is discharged each sodium atom gives away one electron forming sodium ions. The electrons take the external circuitry to reach the positive terminal.

How long does a sodium sulfur battery last?

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.

Where did the sodium sulfur battery come from?

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.

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.
