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…
If you poke a hole in it, is it just as exciting as lithium?
A different kind of excitement without flames.
Sodium cells have been out of the lab for at least 8 months now.
They’re still a bit pricey but the price is quickly falling
These are more fun then lipos… I wounder if u pack a tesla full of these…will it manage to achive escape velocity after a crash? I mean gas cars and lithium batteries right now just tun car into lots fo smoke and flames…but these might really change how we see crashes…
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.
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.
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.
My hopes of flying cars has been dashed 😐

It is if it’s a dry electrolyte cell.
