GAB: 'This explains why Tesla cars were burning up in Fl…'
Anyone remember the Ford Pinto and it's exploding gas tank when impacted. Yet, this is perfectly fine?

While we're very happy to have you in the Gulch and appreciate your wanting to fully engage, some things in the Gulch (e.g. voting, links in comments) are a privilege, not a right. To get you up to speed as quickly as possible, we've provided two options for earning these privileges.
This is a lithium primary cell. It is not rechargable, and does have a lithium electrode.
Tesla and other EVs use Lithium Ion cells. They are rechargable, and DO NOT contain lithium in metallic form. The reason lithium ion cells are flammable is the organic electrolyte, NOT the lithium.
https://en.wikipedia.org/wiki/Lithium...
Lithium Ion (and all) rechargable cells have an internal impedance (resistance). When current goes through this resistance, during discharge (operation) and charging, it generates heat, and increases temperature. The smaller the cells the bigger the challenge in removing the heat.
EV battery packs are energy dense, more and more as the attempt to reach operation (never chemical) parity with combustion fuel. Since they are getting smaller and smaller, the same heat increases the temperature faster (less thermal mass). Almost all the EV packs I am familiar with are actively cooled. Air or other coolant is circulated within them.
We make an Energy Magazine for the US Navy. It is a large, rechargable battery pack to decouple directed energy weapons from the ship's distribution system. The requirement are that cell failures do NOT cascade to adjacent cell trays. Testing is severe. Of course this battery uses commercial batteries (18650 et al) like EVs, however, the physical protections limit the energy density somewhat. They should be safe unless hit directly with an actual weapon (Navy round or missile. Small arms are one of the tests we much conduct.
if not, try it, from a safe distance
a VERY safe distance
Success in the Navy test is to contain the consequences not to cascade to other cells and bypass the damaged subset of cells.
If a Tesla burns: OH THAT IS NEWS. (due to being quite rare even on a per-model basis)
If a gas car burns, eh, that isn't news. Yet it happens all the time.
try putting out a lithium fire
if you dare
and the battery is often damaged and can burn long after the damage it receives, unexpected

When I was in HS, we put lithium in water to show the reaction. That was the early 80's and the heat was already on from stupid Karens and administrators.
I was a Chemistry aide, and the Vice Principal came into the lab and told us we needed to separate two gas cylinders, so we wouldn't have an explosion: Oxygen and Helium. I told him if we did have a reaction we'd be the first high school to get the Nobel Prize.
I just attended a HS graduation for one of my daughters on Saturday. It was interesting to see who the student body actually clapped for. Not a single member of the Board of Trustees got anything more than a golf clap. Several of the teachers received warm, congratulatory hugs from grads.
They have compounds with Xenon and Neon, but that is as far as noble elements have gone (at least in 1984, when I last checked).

In college we had a professor who combined literature and history. Connecting the literature of the day with architecture and even furniture was interesting and made me remember thing rote approaches never would. I look a math and science that way.
The Pinto issue was ridiculous. It was a great car. As good or better than the Jap crap of the age.
I think if the lithium sheet were exposed to water it would react the same, charged or not. The reaction is natural between two elements and doubtfully has anything to do with the amount of charge.
not that i eat fish
in fact, you see me eating fish, the Apocalypse is here
i do n0t listen to doctors much anymore
not after this covid crap
My dad and brother would weight and seal glass milk jugs with calcium carbonate within. Hardly a soul in the McGilvray Bottoms to complain.
you are sitting on a bomb.....
thanks biden the usurper
