In addition to the article’s stated benefits of faster charging than Li-ion, less temperature sensitivity, and lower propensity of thermal runaway, does switching to sodium also potentially address a raw materials problem? (Imagine if desalination could be made ecologically viable by harvesting the waste sodium for batteries…)
And what’s the downside? More complex chemistry to make the cathode?
- Roark66 9mo agoThe downside is incompatibility with the existing tech (voltage mostly).
- MattGrommes 9mo agoThey're also heavier, which is a concern for use cases like cars. There's a good video I just watched that addresses the sodium battery industry and differences with current batteries: https://youtu.be/nrTCgZmUFCY https://youtu.be/nrTCgZmUFCY
- AtlasBarfed 9mo agoSodium ion should be 40% the cost of lithium ion. 60% for LFP. But scaling is still underway. The keys to recognize for advanced sodium ion state of the art is that you should be able to do a 300 mile car now with sodium ion that fundamentally is cheaper than ice drivetrains. However, I still think hybrids are the next 20-year solution
- PolygonSheep 9mo ago> harvesting the waste sodium for batteries But what would you do with all the waste chlorine?
- dcrazy 9mo agoDepends on whether it would net out to be cheaper than the other ways we currently make chlorine.
