I think LFP is amazing. Charging to 100%, no babying it, safer, cheaper, less impactful on the planet, no conflict minerals. It is the clear winner IMHO, energy density aside. It was the sole reason, aside from price, that we wanted RWD.
As to my change to LR - I did some research on battery degradation and accepted that the chemistry in LR is more prone to it, and looked at data on high milage Teslas. The worst case I have seen on the modern LR chemistry is
12% loss after 100,000 miles on a 2020 performance M3 on which 50% of all miles driven were supercharged, the car was regularly left at low or high state fo charge, run down to zero and into the buffer before being hit while hot with a supercharger. It was beaten to hell. I'm astonished it was not worse. Tesla's thermal management is second to none and it isn't even close, the car knows how to manage itself. Even if the car loses 12%, that's a EPA mixed rated range of 315 miles. That is MORE than sufficient to fully replace an ICE and road trip. I think the worry about it is valid but also, over-blown because they are very expensive and folks don't want to buy something that isn't solid. But, these cars are not new anymore. You are not beta testing the batteries. They're tested and vetted. Watch that video - Kyle has every electron ever used logged, no one has data as he does.
Now, there is no good answer about the ethics of mineral sourcing for the LR batteries. It is harsher on the planet and there's a real risk they came from operations that mistreat our fellow man. I made a call that switching to an EV and having lower lifetime emissions outweighs the bad. Not everyone feels that way.
