Not every day that you see 7++ Teslas go up in flames skip to 9:05 on this video

Gruber !.. one of the few companies that will repair Tesla batteries..
i wonder what their insurance premiums are now ??
But even in 2017, the fire dept had “no ideaa” how to tackle a lithium battery fire.. ??
... and just let it burn out !
..worrying !
they should of hit it with a fire hose- water :thumb: maybe they could of saved the other cars.
Of course every salesman will tell you to use their product- it is the American way :lol:

I suspect the fire hose “run off” from any industrial fire is likely to be “Dirty” ...often even toxic.
It is inevitable, and probably considered the lesser evil than an uncontrolled fire.
But drenching lithium batteries in the surrounding area to those on fire, to cool and prevent them burning and adding to the fire, ..has to be preferable to just letting them all burn.
you guys lost me- how does argon foam stop the heat produced by a charged up, and shorted group of 74 cells?
(from spreading to cells nearby in the module that are not shorted, and melting them causing them to short, and so on)

your link is not about 18650 fires. it does not apply.
.
anyway by your logic with no flames, a shorted pack will not catch fire or spread to normal cells, as the heat will dissipate by itself :lol: so therefore there never was a fire in the first place
0.3 grams of lithium per amp hour capacity. that is how much is in a battery. NOT MUCH

There is NO lithium metal in a typical EV battery.
What is involved are LITHIUM OXIDES, and LITHIUM CARBONATE SALTS , an inert compound that does not burn and is infact prescribed as a medication in tablet form.
What burns in a battery fire is the Organic Electrolyte solvents which are used to carry the Lithium salts.

There is no lithium metal in a typical WORKING EV battery. One of the more common causes of fires is overcharge and the resulting formation of lithium metal dendrites which punch through the separator and cause a short. They then overheat, decompose nearby electrolyte, and burn with the oxygen from the decomposed electrolyte.
Yes, certainly a “Spinel short”. Can initiate a fire, ..but that would be isolated to a single cell without the “thermal runaway” effect of other close cells bursting into flame , despite no spinels ?
The rapid explosive “Popping” of 18650 type cells in a pack fire is due to the heat transfer boiling the volatile solvents , which vent into an existing flame area and ignite, adding to the runaway event.
Even “New” packs (presumeably with little or no metalic Lithium ) are known to burn violently if seriously damaged, probably causing a “mechanical” electrical short, which again overheats some cells
I have seen videos of Lipo packs with different Electrolyte compounds, that do not burn , even when overcharged and damaged/pierced. But obviously their performance characteristics were compromised by the sub-optimum electrolyte trade off
