We've all seen EVS on fire a result of the lithium ion battery which provides the power to the car experiencing a condition known as thermal runaway. This is when one of the individual cells in the battery is either damaged by an impact or just degrades over time to the point where it causes a short circuit.

This generates heat in the cell which causes an outcof control chemical reaction to become self- sustaining very quickly the heat spreads to the cells nearby heating them to the point where they also go out of control in a kind of avalanche until frequently the whole battery and the car is destroyed.

The scariest thing that can occur when a lithium ion battery degrades or is damaged is a Vapor Cloud Explosion (VCE)

When a lithium ion battery is on fire the escaping cocktail of gases which are highly flammable are at least being consumed in a fairly controlled way. As the flammable gas escapes it is burned in the fire and is therefore no longer capable of combustion. This doesn't apply to the toxic elements of the gases which remain a significant danger and are a separate problem to be dealt with by the First Responders.

However if these flammable components do not initially catch fire, they can accumulate especially when the vehicle is in a confined space such as a parking garage. A source of ignition would then set off the entire gas cloud resulting in a violent Vapor Cloud Explosion.

What's amazing is just how much gas is produced from a battery: it's between 500 and 6,000 liters of gas for a single kilowatt hour of battery capacity. Your average EV can have 60, 70 even 100 kilowatt hours or more battery capacity.

I'm going to hand over to Professor Paul Christensen, an expert on advising First Responders on lithium ion battery fires. You should watch the entire video at the link. He doesn't mince words. At the start of the video he says that lithium ion batteries are “thermodynamically unstable and shouldn't exist.”

The next key point is how much vapor cloud is produced. This is experiments we did in Spring 2021. Again nail abuse (battery penetrated by nail). It doesn't matter what kind of abuse. Again you will see the heavy metal particles blasted out first. Now the Lower Explosive Limit (LEL) for the vapor cloud is believed to be between 6 and 11%....heavy in metal nanoparticles. Lower explosion limit but the L is way above the immediate danger to life and health. Got HF Etc. What we realized from our experiments in the literature if you only partially charge a lithium battery and you abuse it, it need not ignite. You can either delay ignition or it doesn't occur at all, then the hazards flip from fire to explosion. Fom our research we reckon it's between 500 and 6,000 Liter per kilowatt hour of Vapor Cloud not including the small droplets of solvent you always get. Two forms of vapor cloud: heavier than air and lighter than air and only one dominates. We don't know how to predict this yet now you can see the heavier than air Vapor Cloud (video). Imagine that in the bedroom cupboard on the third floor of a Terrace house with a battery energy storage system next to the hot water tank. Lithium ion batteries going to become unstable at about 70° Centigrade.


Wow! The video that MGUY shows is incredible. I highly recommend everybody watch it to see what happens with Li-ion batteries fail in your house or apartment. You have just SECONDS to get out to save your life.

Now we can see why insurance companies are so paranoid about changing out the battery for the smallest scratch (like the poor guy in British Columbia where his car was totaled for a scratch).

The Greeniacs must be stopped!

These video stills are taken from the embedded video in the linked YouTube video. This was an apartment in China. Time stamps are in the upper left corners. Six seconds from the guy grabbing his child and fleeing the room to fireball!


I updated my long list of what's wrong with EVs to include VCE:

Great list—and of course there is “cold” and then “really cold”.

The decline in battery functionality is worse than linear.

They don’t even test these bricks below twenty degrees.

My only question about the list is the 10,000 mile tire life assertion.

That’s an 80% life reduction from the usual 40 or 50K miles.

I thought the effect was more like 25%. Got a reference?

If the circuits that protect the battery allow it to be charged when there are cells which have not reached a high enough temperature... those cells are damaged or destroyed. One damaged cell among hundreds or even thousands can cause the battery to self-destruct.

One of my hobbies is playing with small drones. Even the little batteries that I use in them can put on a spectacular show and destroy the drone. That is why you always get rid of any battery that shows signs of damage. Sometimes you notice a bulging cell, sometimes you notice that they are going dead sooner than they should, many times the primary charger that I use indicates there is a problem.

The scariest thing that can occur when a lithium ion battery degrades or is damaged is a Vapor Cloud Explosion (VCE)

So as an EV battery degrades over time, the driver and passengers are exposed to a toxic vapor cloud?

My father was working on battery research from his PhD in the early 1960’s until about 1980.

He gave up on them, and moved on to other reasearch areas: physics of surfaces, crystal growth, catalysis.

Lord, I wish he was still here, but one of the things he said was that the Lithium ion batteries were just too dangerous.

Also, nothing fundamentally has changed in battery developments since 1980.

Everything is a refinment of the Li ion batteries of the 1970’s.

There are still safety issues. And, ironically the batteries have much less energy density than motor fuels, while being much more dangerous.

“Vapor cloud explosions prevent climate change”, is the next environmental claim.

If your car does not explode, you’re a selfish anti-environmentalist.

I'm with you. When it was time to replace my wife's old ICE crossover and I replaced it with an EV crossover, I first listed a bunch of pro's and con's for expenses/savings. A "con" was that the EV weighed 10% more than the ICE and, thus, I assumed a 10% more frequent tire change. (But balanced with less frequent brake pad work because most braking in the EV is done with regen braking.) My experience seems to show I was right. I had to replace the tires at about 24K miles. I've now added another 19K miles with little tire wear (we seem to be driving 26K miles per year). Thus it seems the 2nd set is lasting a lot longer than the first set and confirming my theory that tire wear is only about 10% faster than I'm used to in the ICE. Maybe my first set didn't last long because they were factory tires? I'll have a better certainty when the time finally comes to replace the 2nd set of tires. If it's at about 60K miles then they lasted about 36K miles (10% less of 40K).

You will be screwed if you have to evacuate during a hurricane and get stuck on the highway. Only option is to die while looking for a charge station. You may save yourself and family if you receive a ride from a kind driver driving a gasoline powered vehicle. Not to worry — Greta saves.

That looks like a fire to me.

Think of the lung cancer cases and repiratory ailments that await us because of the rubber dust build-up in lungs and bloodstream. Life is good.

I’ve said it before. EVs may, at some point in time, be a safe, effective, dependable and viable means of transportation for the common, working American public. But now is not that time. Many improvements, safety and otherwise, will need to be made. EVs are currently unsafe, undependable and unaffordable to most Americans.

The only reason this is being pushed now under the bogus label of “green energy to combat global warming/climate change”... is because the PTBs have $$$ heavily invested in this, another of their “grand schemes”. And correct me if I’m wrong, but... aren’t the same ones pushing EVs the ones that are all-in and on-board for global depopulation? Do the logic.

“... causes an out of control chemical reaction to ... “

Nowhere do the speakers tell us the makeup of the gases produced other than saying heavy metal nanoparticles are produced.

That omission makes me think that the gases aren’t that toxic.

Who do you believe? Found this headline:

“Electric vehicle fires are very rare. The risk for petrol and diesel vehicles is at least 20 times higher”

I’ll have to look it up. There have been quite a few articles where EV owners are saying they are getting 7,000 to 10,000 miles which (I agree) is hard to believe.

Some people are blaming it on the high-torque motors and people flogging it during their standing starts. I haven’t read much explanation.

Recently, Washington State put a bill in their hopper requiring “low rolling resistance” tires on all vehicles. That means harder rubber compounds which means harsher ride AND less road traction and more tendency to slide. It sounds like a disaster.

“Sometimes you notice a bulging cell”

I had a couple of large auxiliary battery packs for my computer, iPad and phone when I’m away from an outlet. I noticed one of them was bulging a few years ago and immediately tossed it. The manufacturer sent me a replacement based on the photo I sent them.

Is there a capacity / size below which there is no problem? What about one-time, disposable Li-ion batteries? Do they ever catch on fire or explode?

“the driver and passengers are exposed to a toxic vapor cloud?”

I’m pretty sure these cells do not out-gas during normal operation the way lead-acid automotive batteries used to do. I grew up in an era of lead-acid auto batteries and I was taught in the 60s to NEVER make ground contact on the battery terminal because of the risk of a hydrogen explosion. I never actually heard of a battery exploding due to hydrogen off-gassing, but was warned about it. You always attached the red jumper cable to the positive battery terminal, then the black jumper cable to the car chassis away from the battery. That kept the sparks away from the battery.

If the battery sends out a Vapor Cloud, it happens fast and big. You’ll know it’s time to abandon ship if you see that happening.

Ironic, indeed, isn’t it? The energy density of hydrocarbon fuels is HUGE in comparison to batteries, but the liquid fuels can be handled very safely and are stable.

Or maybe Vapor Cloud Explosions are so hazardous to the climate that we need to ban EVs!

These people flip-flop at the drop of a hat. It’s the nature of communism — favored today, on the outs (or dead) tomorrow. And the proles had better well fall in line with the new party doctrine very quickly.
