Excellent video, love the edits! Real question - The 20,000 gallons of water the fire department poured on the car, did it make any difference or did they just waste enough time for the batteries to burn themselves out naturally? I'm thinking the batteries are burning though a sealed, water proof casing. Is the water even getting to the source of the fire or are they just washing the seats and floor mats... and waiting for the fire to go out?
@ACSReactions
@ACSReactions Жыл бұрын
While it's hard to say for sure, huge amounts of water are likely to help stop a battery fire faster than just letting it burn. First off, by the time you have a full on fire, the casing is ruptured, allowing water in. Second, the water doesn't have to make direct contact at the point of the ISC, it just has to pull enough heat away from the battery to break the positive feedback loop that's providing energy and oxygen for combustion.

There are currently about six Lithium battery chemistries. LMC is often chosen due to its high power:weight ratio for EV’s and are subject to thermal runaway. LFP (lithium iron phosphate) batteries by contrast are NOT subject to thermal runaway, and furthermore have about five times the number of charge/discharge cycles. If a battery is to be placed inside a structure (house, RV, boat, etc) then LFP chemistry is the prudent solution for both safety band longevity. 😎

But what does that mean "Electrons are way too reactive to travel through materials on their own"? 🤔

Fantastic and entertaining video sir! I have sent a few li ion cells into TR intentionally and not. The white hot sparks that are emitted with a Fully Charged cell are a sight to behold. Reminds me of thermite reactions. Think about high Nickel cathode chemistries. The Ni0 is callandered on to a sheet of Aluminum which is the positive current collector. .. according to the web Ni0x and AL powder also make thermite... so u see where I'm going with this. Another observation is that below 50% state of charge the cell usually vents Without the thermite fireworks. In a discharged cell much lithium has been transfered to the cathode. I suspect that Li is more strongly bonded to the oxygen than Aluminum, and this prevents the Aluminum from from reacting with the Li loaded Nickel oxide? Your comments please sir.

So interesting, other than the design of the battery itself, they could in fact try cooling the fire faster, say with dry ice or liquid nitrogen! Do you have any thoughts about this?
@FloydMaxwell
@FloydMaxwell 4 ай бұрын
I had a similar thought. Biggest problem is that the fire is in the battery pack, which is always installed at the bottom of the vehicle (to keep a low center of gravity). So you can get water or other cooling agents to the battery directly. In short, the water is almost completely useless, and liquid nitrogen might not be much better. And then you'd have to keep a substantial supply of it on hand, in a tank you could tow behind your fire truck? Logistics are difficult, to say the least.

Lithium Ion batteries were first tested in 2 way radios during the Vietnam war. Thermal runaways had stifled commercial introduction for a long time. I experienced the changeover on video camera equipment where the so called memory effect of Ni Cad cells had to be eliminated. They built in computer chips to correctly charge and discharge them. Portable music players like the Ipod used them and paved the way for introduction into cell phones. Even the Boeing B787 has a blow hole on the side of the fuselage. New electric cars are designed to vent to the bottom giving occupants time to escape.

Water douses gas fires pretty quickly but this nightmare needs a better solution......and if it were ME I would have had a hold on any production of these things until the fire departments and us in general had Fire Extingushing solutions available to make this all safe.

It’s mostly the ones that contain cobalt oxide that are subject to thermal runaway. The cobalt oxide breaks down at raised temperature, releasing oxygen that then reacts with the electrolyte. If a lot of that happens, then it all gets out of control pretty fast. Lithium Iron Phosphate batteries are much safer - no cobalt oxide, but not immune to fire.

For the Swedish research "Putting out lithium ion batteries with plain water in a short time", there's kzfaq.info/get/bejne/at6ad8ee257Zop8.html video that shows how they are looking at coping. Some of the issues are unfamiliarity and 'lack of practice' (see #1). Regular vehicle fires can be much worse, but they are familiar and not newsworthy. The ship fires are interesting as they carry on regardless (i.e they have been happening for decades). The LashFire study webinar kzfaq.info/get/bejne/r9BnabaJstjDn58.html has some real (live) fire demos - the main issue isn't the fuel but the plastics and rubber in the vehicles. Finally there's likely to be a shift to the LFP technology which is a positive temperature coefficient chemisty so doesn't suffer the same thermal runaway problem as Li ion.

That’s it. P.s. Fire departments might want to explore carrying 20-30 gallons of liquid nitrogen in a dewar on fire trucks precisely to deal with things like this.

Statistically, ICE vehicles are more likely to catch fire than EV's, but is that just because the ICE car population is on average much older? It is far more likely that an old ICE has faulty wiring or fuel lines than a newer ICE car. Since most of the EV vehicles on the road today are relatively new, perhaps that is why they are less likely to catch fire. What will happen when there are many times more EV's on the road, and their average age is a lot older? Also, the older the EV is, the more likely it will be that the battery pack has sustained some damage. Look at the EV's in Florida that were flooded in the recent hurricanes. They are ticking time bombs.

Because they cram in far far too many electron ions and anti-ions into a confined space - the battery - and the ions/anti ions far too close each other is like an explosive. Even with rockets the oxidiser is kept separate and only mixed at the last moment.

Lithium is a alki metal putting water with a alki metal produces a fire or an explosive. Would fire foam put out the fire?

After the Freemantle Highway fire and the need to evacuate the ship because the fire could not be extinguished, I wonder how long it will be before there is a serious EV fire on a car ferry requiring evacuation. Certainly on car ferries on the English Channel there do not appear to be any additional measures to deal with EV fires despite the increasing proportion of EVs therefore the increased probability of one occurring in or spreading to an EV from a fire in an ICE vehicle.

Electric vehicles catch fire because... diligent EV manufacturers, of course not from the USA, already install sodium-ion batteries in EVs that are in production and for sale... But USA premium brand EV manufacturers insist on using ternary lithium ion batteries instead of non-flammable sodium-ion batteries as if they don't exist... because they're actually only interested in continuing some sort of transportation fuelling investment substance racket after the obsolescence of fossil fuels. THAT'S why EV fires that shouldn't even exist... are so hard to put out. ,🤪
