It's crazy to me that the rush to go green has meant the dropping of safety requirements that have been built over decades of vehicle manufacture. Lithium ion is an unsafe chemistry that has been allowed whilst we wait for solid state alternatives. In the mean time fires caused by battery thermal runaway are seen but we are told, ICE cars catch fire too , like that is a good reason to sit on a potential bomb that may just randomly explode because of a battery fault. To me, that doesn't sound "sustainable".

[@gregoswald7723]

One of my friends had a lithium battery from one of his radio control cars "pop" and start on fire in his garage. He used a shovel to throw it out into the driveway. I told him to put his RC car in a plastic bin in the middle of the yard, 20 feet from any structure, and run an extension cord to it when charging. He didn't listen. A couple weeks later, he heard a "pop" in his infant son's bedroom. He ran in and grabbed the child out of the crib as flames shot out of the closet. His house was burned beyond repair. Luckily they both made it out alive. If he hadn't had the previous experience and instantly identified the "Pop" sound, and known what it was and what it meant, his son would have died. Had he been asleep at the time, they could have both died.

@@bestrenderings796 I have not personally heard of cell phone batteries blowing up or even starting on fire. I have read about it on the internet. The potential is there if the battery is damaged or if it is charged or discharged too quickly. Anything that causes the battery to overheat is a potential problem. One thing most people don't know is that you should never charge a lithium battery if it is below freezing. Apparently, lithium batteries grow crystals inside, when they are charged below freezing. IF the crystals grow big enough they will short the battery causing a fire. I had two massagers that had two different voltages. I plugged the massager that used 15 volts into the charger that was 19 Volts. After a couple hours, the massager battery popped, throwing bits of hot metal out. Luckily it was sitting on a hard metal surface so it didn't damage anything else. Both chargers had the same size plugs and fit the other.

About a year ago or so, there was a rain event in Florida and many EVs got too wet. For the next week after the rain had stopped, there were several fires as the batteries failed. Don't know if water or moisture seeped into the batteries, or if something shorted them out and caused them to drain too fast, over heat, and ignite. I suspect moister got into the batteries because it took a few days before they started igniting. If they were shorted out, I'd expect them to ignite while still wet. At any rate, California is getting a rain event right now. The story writes itself at this point. On a positive note, most of us enjoy fire works, so it's reasonable to assume that we'll consider these EVs to be just as pretty.

You are ten times more likely per mile driven to have your gasoline powered car catch fire than an EV. Your gas tank with just three gallons in it it contains more energy than a fully charged Tesla Model Y battery and can explosively release that energy in a small fraction of the time it takes an EV battery to combust. Gasoline is scary stuff, although admittedly it is _much_ easier to extinguish than an EV battery once it is on fire.

Glad to find stuff like this and see that not everyone is ignoring the dangerous that comes with lithium batteries in cars and other storage systems. For the past 5 years I have tried a few times to bring up issues with the batteries and also the lack of updating of building codes both for residential and commercial building. But 100% of politicians and even people in the building industry so far have no idea on the issues and dangours they pose still and given the massive rush to ban ICE around the world this will end up causing a lot of deaths and massive insurance costs because the battery tech is not safe for mass use and the infrastructure is not suitable for it. When I park in a multi story carpark or underground carparks and spot electric cars I go park outside even if the weather is crap. Also one simple fix would be on cars to have an emergency battery water deluge system that firefighters can hook a hose too and then pump water directly into the battery pack. It's a minor design change on the battery pack and then the hose connection to the outside of the car behind a flap just like opening up the fuel door and pumping fuel this simple fix means firefighters open/break open the water deluge flap/cover and then hook up a hose and then pump water directly into the pack to then control the fire and cool the pack. Regulators around the world need to work together to design (With emergency groups that have to use any system) the right type of system and connections and also rules on location of the port opening and so on. Also one other thing is location in cars for battery packs. Some do it right with the pack at least separated from the inside of the car yet other rushed to market electric cars that often where based on ICE designs place the packs inside the cabin eg under the rear passenger seats with little to protect the people inside the car from the packs if they decided to go up. Seeing how powerful and fast they can blow up that then means everyone inside the cabin is now at risk of severe burns but also long term lung damage and even eye damage from the toxic off gassing. Why and how manufacturers thought this type of design was a good idea is beyond me but then when regulators are all clueless then the rules are not there and all manufactures will try and take the cheapest solutions in this mad rush to meet deadlines set by clueless politicians and all other clueless regulators.

Li-FePO4 batteries are not new. They have been around for many years. ( F1 used them in 2009.) It is true that they are much less likely to suffer thermal runaway and should not catch fire. Many motorsport cars (including mine) with ic engines use them as 12V batteries to save a lot of weight c.f. lead-acid types. They have been bypassed by road vehicle manufacturers because their specific energy (joules/kg) is lower than chemistries like Li-NiMnCo. However Li-FePO4 batteries maintain their performance over many charge/discharge cycles and hold charge extremely well. So I agree that they are probably the safest bet albeit with reduced range for a given battery weight.

As an EV car owner and lover this is a good video to watch. I don't own a drive way and if I did I'd park my car slightly further away from house after watching this video. In a way the visuals of thermal runaway make sense as my car battery can hold up to 64kw (usable, more actual), if I stood in front of 64x 1kw heaters I think bad things would happen as well. Huge power numbers. I do agree that home battery storage probably shouldn't exist as long as it has the potential to do that. I'm more a fan of using the car battery as the home energy storage - at least it's a bit safer that way. There is a lot of research and upcoming new batteries that are a lot safer and I think the industry does realise this. One sidenote is ICE cars do catch fire: I don't know the numbers but did see an ICE car fire about 5 years ago on the hard shoulder, only just happened maybe 2 mins before, but was well on fire, during summer, within that time it had also caught the fence, tree and field on fire, fire brigade were about 1/2 mile away while I was driving past on the other side. No mention of it anywhere in any news. How often does that happen? And what are the common causes of a random ICE fire while driving along? I guess it's not news if it happens all the time..

I have been in the fire prevention industry for a number of years, if enough education of the public is done, of the causes of fires, most of us shouldn’t buy the furniture and mattress we all have in our homes, these are stuffed full of highly inflammable toxic foams. We shouldn’t wear those polyester fleece and puffer jackets, but we do. There’s no question that EV batteries are highly inflammable when damaged but EV batteries like those in a Tesla has a Battery Management System (BMS)to regulate charging and temperature control to prevent thermal runaway, unless it has been physically punctured. That can’t be compared to an E-Scooter, these do not have BMS. Not all lithium batteries are the same or made the same either. Fires do happen even with gas cars, in fact there has been a lot of fires with gas vehicles and many deaths too.That doesn’t mean we should also not drive gas vehicles right? So education of firefighters and users and general public of lithium batteries fires is required like all new technologies introduced. Not many of us will give up our lithium batteries operated mobile phones, our computers and tablets etc. We need lithium batteries, the issue is how they are made, maintained and used.

There are six types of cathodes for Li-Ion batteries. Three of which are employed commonly in EVs. One of them is LFP (Lithium Iron Phosphate), which I would consider the only reasonably safe variant. But LFP is rarely chosen, because of its low power density. The other two (NMC and NCA) have a much higher power density but are also much more dangerous. Dr. Christensen is talking about the importance of education. It would indeed help to include the distinction of different Li-Ion battery types in that education. EVs with LFP batteries should not be subject to the same restrictions as the other types. What I don't know is if the response to a unlikely LFP fire should be the same as NMC and NCA. Does it release the same amount of gas? Can it also undergo thermal runaways if the conditions are ripe for it? Or is inherently save and self-extinguishing?

From the Seminar, it would appear that all Lithium Batteries are unstable. But there are billions of Lithium Batteries in Phones, Laptops, around the world. I read (recently), that there have been 464 (verified) EV Car Fires around the Globe. Considering that there are now 26 million EVs around the world, the % of EV fires is very low - when compared to ICE vehicle fires. How many (very modern) ICE vehicles today - have a plastic fuel tank?? I have to agree that any Lithium Battery Fire can be extremely dangerous, but (in life), we run risks every day. It is through the valuable work done by Dr. Christensen, we will have a much safer world, and hopefully overcome the issues with Lithium Battery Fires.

@@alkaholic4848 EV's are powered by the grid mix (or your own PV if you have it) which is lower carbon than the grid mix nearly everywhere. The grid carbon intensity is lower than fossil fuel intensity almost everywhere. e.g. in the UK it averaged 153gCO2e/kWh which is several times better than gas (~600-900, depending on leakage rates) or coal (850-1000). And the global grid was down to 436gCO2e/kWh at end 2022. Transport is about 20% of emissions. Road transport is 70% of that. Combustion vehicles are not 'a drop in the ocean' - they are a very significant chunk of emissions which has to be tackled along with everything else.

That’s why I’m moving my solar storage batteries into a purpose-built shed in the garden as soon as possible! Makes sense to have a vent to the outside just in case, it’ll prevent the shed bursting with the amount of gas liberated! There should be a database of installed lithium batteries the fire brigade has immediate access to. Might help avoid unexpected encounters, especially if the battery hasn’t caused the fire but becomes involved.

Wow. Thank you! This is an essential topic that requires massive public awareness. It is hugely worrisome as they electrify the world...I cannot imagine the destruction this will do to all forms of life and it's environment. No wonder our oceans are on fire....

please take a look at our archive and conference at www.tallbuildingfiresafety.com

It'll do an awful lot less destruction than continued use of fossil fuels will. All dangers are relative. The 'oceans are on fire' due to greenhouse gases, not battery fires.

Just checked. The oceans ARE NOT on fire.

@@aeroearth Not literally: it's a figure of speech - they are hotter than they have been for thousands of years. 90% of the warming ends up in the ocean, and from April last year ocean heat has been the highest since records began, and probably a long time before that too. Read Carbon Briefs "State of the Climate: 2023 smashes records for surface temperature and ocean heat" to get an idea of where we are at. Even allowing for El-nino temperatures were significantly higher than expected last year, and it's not yet clear why. This is what people are referring-to when they say 'The oceans are on fire'. It's shorthand for 'things are bad, the hottest they have ever been, and even hotter than modelling suggested they would be, which is also concerning'.

[@rogerphelps9939]

We are now not needing to imagine the massive destruction that internal combustion engines are doing to all forms of life and the environment because it is happening right now in front of our very eyes. EVs are part of the answer and are very early in development. There may be a few fires but far less frequent than ICE fires and Evs are improving all the time.

[@UncommonSense1776]

If it’s a thermal runaway, could they be controlled by super cooling the system with something like liquid nitrogen?

[@aeroearth]

Or of course you could just buy an internal combustion engined car with technology developed and perfected over the last 120 years.....................
