The big deal is it's made out of sodium. Anyone with access to sea water (which is full of Na + Cl) can make these batteries, and it's unlikely we're going to run out of sea water in the near future, or even next 3 billion years.
Sodium batteries will probably be the go-to for grid scale battery in (wild guess) ten years and some of the ultra-cheap electronics. Sodium, Li-ion and lifepo4 all have significant overlap in the 2.5-3.7v range so there's a lot of potential for compatibility/interoperability
Compare with lithium batteries, which currently there's only a handful of high quality lithium deposits that are convenient to be mined
- anticorporate 2y ago> it's unlikely we're going to run out of sea water in the near future, or even next 3 billion years. I hate to break it to you like this, but the oceans will evaporate in about a billion years. https://en.wikipedia.org/wiki/Future_of_Earth https://en.wikipedia.org/wiki/Future_of_Earth We should still have the sodium, though.

- yetihehe 2y agoSometimes we even treat sodium chloride as leftover byproduct[1]. "[...]as of August 2016, it covered 98 hectares (240 acres) and contained approximately 201 million tonnes of salt, with another 900 tonnes being added every hour and 7.2 million tonnes a year." 7 Megatonnes of unused salt a year. The problem with using sodium from that mountain - what to do with leftover chlorine. [1] https://en.wikipedia.org/wiki/Monte_Kali https://en.wikipedia.org/wiki/Monte_Kali
