That's mighty hard of you to really claim, since EV's only started to become common about 12 years ago. It wasn't even until 2017 that the EV market broke 1% of vehicles on the road. Li-NMC batteries will eventually fail. They haven't been in EV's long enough to say they'll likely last 15 years. If they industry was really sure they would, the warranty period on them would be better than 8 years or 100,000 miles to provide 70% total capacity. If I only had barely over 2/3 of my battery capacity left after 100k miles I'd be pretty upset.
Well the original model Nissan Leaf has been available in the UK since about early 2011, which is more like 13.5 years than 11, and I did a quick search for the 2017 Nissan LEAF on more than 100k miles on autotrader and only one of them had lost any battery capacity at all, and it had over 90%. Another one had 120k miles on the clock and was still at 100% battery capacity. You can mistreat a car and it won't last as long, yes, but it really is the older model that has the common battery problems. The new ones don't. And there are brands that have much better battery care than the Leafs, with active cooling etc.
You see, the reason we know they're lasting longer is, you know, science and math, where they measure stuff and do the sums, and given that the old type of battery declined a lot in the first 8 years and the new type isn't declining, then all you've got left on your hands at the end is just an awful lot of FUD about battery life peddled by an awful lot of people who don't actually know.
