My hopes of flying cars has been dashed 😐
Comment on Lithium-free sodium batteries exit the lab and enter US production
Nindelofocho@lemmy.world 4 months agoThat 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.
