Early Nissan Leaf batteries degraded relatively quickly (8-10 years) due to poor battery chemistry and no thermal management. Both of these issues have been fixed in all new electric cars (except the new Nissan Leaf which still doesn't have battery cooling).

Even the old degraded batteries are valuable as static energy storage, and several people are using them as house batteries.

Most of the cost of a battery replacement is the manufacturer markup. There is at least one company making replacement Nissan Leaf batteries for significantly less than Nissan, and they include the latest chemistry and liquid cooling (unlike Nissan who just give you a second hand battery).

Most electric cars today have a 10 year warranty on the battery. Manufacturers wouldn't be offering that if there was a reasonable chance you would need to replace the battery in that time.

Even if today's EVs degraded like the first Leaf, when you start off with 250 miles of range you could lose a third of it and still have a very usable vehicle.

Would you mind sharing which EV you have that has a battery that will last 22 years with normal use?

I have a 2011 Nissan Leaf AZE0 24kWh with about 40% battery degradation. It can drive about 80km (50mi), which is perfectly adequate for a second car. It is rarely driven more than 20km in a day.

My other car is a 2018 Nissan Leaf ZE1 E+ G 62kWh with about 4% battery degradation.

The fastest battery degradation happens when the battery is new, and the degradation slows down gradually over time. I expect the 2011 Leaf to still have at least 50km range in 2041, and the 2018 Leaf to still have at least 200km (130mi) range in 2038. Both of these will still suit my needs.
