  • National Standard for Sodium-Sulfur Batteries

    National Standard for Sodium-Sulfur Batteries

    Sodium-Sulfur (NaS) Batteries During electrochemical cycling, traditional NaS batteries oxidize (discharge) and reduce (charge) Na at the anode and reversibly reduce (discharge) and oxidize (charge) molten sulfur (S) at the cathode.


    FAQs about National Standard for Sodium-Sulfur Batteries

    What is a sodium polysulfide battery?

    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.

    What is a sodium ion battery?

    Sodium-ion batteries (NaIBs) were initially developed at roughly the same time as lithium-ion batteries (LIBs) in the 1980s; however, the limitations of charge/discharge rate, cyclability, energy density, and stable voltage profiles made them historically less competitive than their lithium-based counterparts .

    What is a Technology Strategy assessment on sodium batteries?

    This technology strategy assessment on sodium batteries, released as part of the Long-Duration Storage Shot, contains the findings from the Storage Innovations (SI) 2030 strategic initiative.

    What is a sodium metal halide (NAMH) molten salt battery?

    Sodium Metal Halide (NaMH) Molten Salt Batteries NaMH batteries (e.g., Sodium-Nickel Chloride [Na-NiCl2 or ZEBRA]), like the NaS battery, rely on the oxidation and reduction of Na at the anode and utilize an ion-conducting ceramic separator; however, they rely on the reduction and oxidation of a nickel chloride/nickel-based cathode (NiCl2/Ni).

    Why are sodium sulfur batteries more economical?

    Like many high-temperature batteries, sodium–sulfur cells become more economical with increasing size. This is because of the square–cube law: large cells have less relative heat loss, so maintaining their high operating temperatures is easier. Commercially available cells are typically large with high capacities (up to 500 Ah).

    Are sodium batteries a good choice for energy storage?

    Much of the attraction to sodium (Na) batteries as candidates for large-scale energy storage stems from the fact that as the sixth most abundant element in the Earth's crust and the fourth most abundant element in the ocean, it is an inexpensive and globally accessible commodity.
