Costa Rica sodium sulphur battery

What is a sodium sulfur battery?

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.

What is a sodium polysulfide battery used for?

However, due to the high operating temperature required (usually between 300 and 350 °C), as well as the highly corrosive and reactive nature of sodium and sodium polysulfides, these batteries are primarily suited for stationary energy storage applications, rather than for use in vehicles.

Should NaS batteries be co-located with hydrogen production?

Not surprisingly, NAS batteries have been chosen in several recent projects for co-location with hydrogen production. Across the globe, testing and certification of energy storage technologies from cell to system level according to UL9540A and UL1973 standards is becoming crucial for bankability.

Is sodium-ion a make-or-break year for the battery market disruptor?

Data adapted from Wood Mackenzie, “Sodium-ion update: A make-or-break year for the battery market disruptor,” January 2023 .

Does BASF sell NaS batteries?

Today, BASF not only distributes the NAS battery worldwide, it is also working with NGK on the next generation of sodium-sulfur batteries, with product launches forthcoming in 2024. To learn more about NAS batteries, visit the BASF website here.

Are Na batteries a supply chain problem?

Supply Chain Supply chain was a repeated challenge for multiple Na battery types, particularly around electrolyte materials. For NaIBs and NaMH batteries, this concern included electrolyte salts, and NaMH also registered concerns over the volatile price of nickel.
