Car fire blanket for garage

[Archimedes]

Maybe you should just keep a supply of marsh mallows and skewers close by, instead of a blanket.

Mmmm, toxic smores... ?

The electrolyte in a lithium ion battery is flammable and can/does actually burn like any other fire.

google:
Batteries filled with such a type of electrolytes do not contain any volatile components and therefore, they are not flammable. Room temperature ionic liquids (RTILs) are characterized by negligible vapor pressure, which makes them non- flammable.

@Archimedes has the best advice so far in this thread. Ideally get fire/smoke detection, connected to a monitored service that can alert you and emergency services even when you are not at home. Once a battery fire has begun, your car is probably destroyed, so the goal should be rapid detection, intervention and prevention of collateral damage.

My garage has fire rated walls and monitored smoke and CO detectors. Also a video camera. I’m not sure about the interior door fire rating but now I must check on that…

"The electrolyte in a lithium-ion battery is flammable and generally contains lithium hexafluorophosphate (LiPF6) or other Li-salts containing fluorine."

https://www.nature.com/articles/s41598-017-09784-z

"However, lithium-ion batteries are extremely sensitive to high temperatures and inherently flammable. These battery packs tend to degrade much faster than they normally would, due to heat. If a lithium-ion battery pack fails, it will burst into flames..."

https://www.ionenergy.co/resources/blogs/battery-safety/

"The electrolyte consists of lithium salt in an organic solvent (lithium hexafluorophosphate) and is highly flammable."

https://batteryuniversity.com/article/bu-304a-safety-concerns-with-li-ion

Oh and from the article that you linked to...

"...these organic electrolytes have high volatility and flammability that pose a serious safety issue..."

and

"Flammability of the vented electrolyte is a significant unresolved safety issue issue for Li-ion batteries."

The quote that you cherry picked from the article related to an alternative type of battery that would solve the problem, if it were viable.

I’m not a chemist, I just wrote what i’ve been told by a friend of mine, a chemist.
I also remember a discussion (not here), that batteries are not flammable…. And that’s the reason why firefighters couldn’t do anything.
But I have no intention to fight with you.

Agreed. Not trying to argue, just to state the facts. The battery in a current EV is 100% flammable due to the electrolytes. My guess is that your friend is referring only to the chemical reaction that starts the process of excessive heat buildup. But that process eventually results in the electrolyte catching on fire and/or exploding.

It is true that simply denying oxygen doesn't solve the problem, because it won't stop the chemical reaction going on, and the electrolyte will just resume burning when oxygen is restored. Plus, there's no way to 100% deny oxygen in a fire like this, so a blanket would be of no use.

I thought you were supposed to fight fire with fire. I’m gone keep some matches and a zippo in my garage.

Or maybe some fireworks. Then at least if it goes up in flames it’ll be pretty.

Given all of the Taycan car fires and the huge risk that this journalist has identified

https://www.teslarati.com/porsche-whistleblower-taycan-battery-charger-fires-coverup/

since EV hires are really hard to put out (see the above post about submerging the car in water), I took a different approach.

I had a 6 foot hole dug underneath my parking spot that I filled with water. I then had a trap door put on top that would spring open if the sensors detected a fire above.

But wait, BEFORE you do this, there is another thing you need to do! You need to add a quick drain plug, so you don't have to wait forever to get the water out and you need to add a winch above the car so you can pull the car out after the fire is out and the water has been drained. Otherwise, it just takes a lot of work.

I didn't think about that last part until I had the trap door unfortunately have a sensor failure and I had to get my car out. It was a major hassle, but at least I knew that I would be safe from one of those dreaded fires!

As my "garage" (chalet is more closer) is almost ready,

I'm wondering if I should have a car fire blanket ready to be used,

What's your opinion/experience?

Cheers

Is there actually an issue with Taycans spontaneously combusting?

That phony article again…. I trust your post was sarcasm.

For our own concern ... this is a lithium foil into water ... let's pray for our batt. pack to be super trustable

Afaik, on oil fields, they are (were?) using explosives…which takes oxygen out, so flames can’t “breath” anymore…
