Can you elaborate on that? I was just reading the data sheet for these batteries, and these are tested with a ballistic penetration test, resulting in no fire.
I’m presuming this concern is from watching videos of elemental sodium reacting with water, which stands to reason, but I’ve not heard of exploding batteries
Interesting. I wonder how that compares to a similar Li-ion cell. Also it’s a shame there wasn’t a close-up on the markings of the battery in that video to know what it is exactly. I don’t imagine all cells are equal.
The battery packs from the article, for instance, are not constructed from cylindrical cells, but from large thin and flat square cells. The cathode material appears to be unique as well, as far as I can tell; who knows what’s in those blue cylindrical cells.
