Two years ago, sodium-ion battery pioneer Natron Energy was busy preparing its specially formulated sodium batteries for mass production. The company slipped a little past its 2023 kickoff plans, but it didn't fall too far behind as far as mass battery production goes. It officially commenced…
That explosion doesent seem much bigger than a firework thats smaller than the battery’s size. With as much as a car weighs and the amount we already do to protect batteries in electric cars i imagine the explosion from these could be easier to manage safely than a lithium fire. I also wonder how harmful the fumes are compared to lithium
Especially considering there’s no fire from a sodium cell, just a quick bang. They definitely seem a lot safer.
Yep, less/no fire is very important when creating battery banks with many cells. The probability of single cell failure spreading to adjacent cells is reduced, making a catastrophic failure of the entire bank less likely.
We already know how to take care of this in big capacitors. You put a breakaway vent in.
Yep, cylindrical Li-ion cells like the 18650 already do this.
My hopes of flying cars has been dashed 😐
