This isn’t even close to true, fwiw. You can easily find stats on EV batteries. There are early Teslas out there with 200k+ miles after 10+ years with minimal degradation.

Those are outliers. It's like saying there are people who live upto 106 years easily.

These batteries are subject to extreme temperatures routinely including fast charge/discharge cycles and we simply can't escape the physics with our wishful thinking alone.

We can’t escape physics, but we can address physics. Car batteries are usually temperature controlled, they are cooled when fast charging etc.

Especially with modern battery tech, you should easily get 200,000km out of the battery before it drops to below 80% of its original capacity

How are they exactly temperature controlled? To control temperature, we would need to circulate something around the cells and that something has to be heated or cooled whereas every tear down I have ever seen of EV batteries contains nothing as such.

Not to mention that such heating/cooling would additionally draw energy thus taking a toll on both the range and battery life.

For actively cooled car batteries, they’re not outliers. At this point, the onus is on you to show the generally accepted data about EV battery lives are wrong.

You aren’t going to be able to find legit data that says EV batteries regularly fail around the 3-5 year mark, like phone batteries.
