Nope, just calling out people who might be trolling.
Yes, I am trolling, because Ford's relation with both SK and LG are at breaking point, ditto GM with LG. If you have ever developed high power Li ion battery, you know it is ABSOLUTELY impossible to avoid fire, blaming the fire on them will cause BOTH to quit in a matter of time, according to my sources with both companies.
Note pouch cell has bulging issue, but prismatic has heating issue, while cylindrical cell has poor packing efficiency and more difficult BMS design, each con I cite here will make it more likely to catch fire (but I don't know which one is the worst, my personal preference is the prismatic cell). None of them are immune from fire and all of the EV fires are very violent.
Someone has to force the Fed to let battery maker/automaker get some kind of immunity, or they all gonna quit the EV business in a couple of years.

If you drive a F-150 lighting, make sure you always have a plan to exit (while on highway) in seconds, or you could be burnt to ashes, its fire will be a lot worst than this due to much larger battery pack

For someone who is apparently educated, you really don't have a grasp on how to use forum software that has been around for almost 25 years...
Very sharp tongue with poison in it.

As someone who worked on batteries for 15y and someone who followed the auto industry for 20y, my suggestion: either suck up the idea that EV can never be fire-free OR avoid buying a F-150 lighting. I have communications with folks at Ford ( Ted Miller's team), LG/SK and also know 2 guys at GM, EV will always be compromised in terms of "how fast can you charge it" AND "do I lose range in frigid condition".
These F-150 lighting already on the road, there will be spontaneous fires, absolutely 10000% confident of that, since the battery is underneath, when you drive it and see smoke, you may not have 5 seconds to get out safely.
The LFP based ones will be even worse, partly because CATL will NOT be allowed to bring the safest recipe to Michigan, partly because the iron particles will always be present, if you park inside your garage, it can burst into a huge fire at 2:50AM. Think over it!

My personal experience:
1). US is a country excessively relying on stock market to become rich, hence forcing companies to focus on quarterly results, where research/development can take years or decades, so ideas with NO immediate return will get dropped because investor interest takes priority. I see no change of this, there will be more bad things to come. (Even the so called in-sourcing of manufacturing will NOT succeed, there will be LONG-TERM issue despite short-term gain, please MARK my words in 10-15 years when US loses lead in semiconductor, aviation, biomedical industries. )
2). In 2007, 2008, VC will literally rape you by inserting money into your anus (we need you to innovate and make revolutionary discovery, please take my $$ and DO innovation).
3). If you propose working LFP to VC, they said there is no innovation because LFP is 10-20% less than NCM chemistry, we need you to improve performance by 10x, 100x and decrease price by 10x, 100x (I exaggerate a little bit, but you get the point).
4). So someone like me will work on innovative battery ( I used pure gold to make battery, if I succeed, the battery is shit, it may cost $6m, produce an EV range of 20 feet [no typo], obviously I didn't want to do such shit, but VC insist on it (in my case it is Battelle Venture, other VCs are the same.
The country is on the wrong track, as a scientist, the last thing you want is to have some idiots "direct" you to work on something, also the media hype and the fraud by Tesla ( they are fraud, PERIOD) makes people believe battery price can drop and battery performance can increase by 1000x in 30 years, but there is no Moore's law.

Maybe if we as a country had focused on battery research over the past 30 years the way the Koreans and Chinese have done we wouldn't have needed to partner with outside companies.
Our University's have been come obsessed with the Theoretic aspects of science not the marketable types of it; and Industry led by accountants and MBAs have become obsessed with the bottom line and out source every component them can because they care more about the quarter and year than year 5 and 10 or even 20. Then you get into grant agencies of funding research labs that is focused on the person who runs the lab than what actually the lab produces and worse even after it is published YOU CAN'T DUPLICATE THE RESULTS!
Ford to build $3.5B factory that will make two kinds of batteries with Chinese partner

Kidding of course, I have tremendous respect for Ted J. Miller, Ken Snyder and the group they lead at Ford, the constant concern for battery fire is draining them.
Ford/SK dispute could eventually make the EV business go away completely, despite LG/SK had atrocious relation, but they are both unfairly targeted for EV battery ( The fire root cause analysis is often impossible and the fire hazard will always be there, in 5y, 20y and 60y, it will never go away), the regulator and the consumer eventually have to accept that. IF you have Ford and battery partner foot the bill for the inevitable fire hazard, the EV price has to go up significantly. Now you understand Toyota very hesitant to enter EV business, the non-issue run-away Toyota caused $5.4B loss for them, a large battery fire induced recall will wipe out the supply chain overnight ( no one can pay $400B in a recall). If Ford recall 800,000 F-150 in 2025, it can cost them 15-20 billion dollars.
