> We haven't seen a weight-based energy density figure from Natron itself, but a 2022 article from Chemical & Engineering News put its sodium-ion batteries at 70 Wh/kg, around the very bottom of the sodium-ion energy density scale. That aligns well with the company's stationary-only business plan, as sodium-ion batteries being pursued for potential mobility use have more than double that density. CATL showed a 160 Wh/kg sodium-ion battery in 2021 and has plans to increase that density over 200 Wh/kg to better meet the needs of electric vehicles.
CATL’s sodium batteries were more than twice as dense three years ago
- ZoomerCretin 2y agoYes, but since the US is becoming extremely protectionist/nationalist with its energy infrastructure, the only relevant bit from this story is that this production is occuring entirely within the US. Though it is good news that this company can produce much denser batteries in the future!
- gpm 2y agoEnergy density isn't a particularly interesting target for stationary energy storage applications. I'd assume that they just aren't optimizing much for it (yet).
