I can tell you from personal experience our 2017 e-Golf that now has about 81k miles on it still calculates to something around 90+% of its original range, indicating little degradation. I have spent time with a lot of evs and this car is in my opinion the winner among the cheaper short range cars for handling and driving enjoyment (why we bought it).
Mine will be for sale shortly so stay tuned if you want a super nice car under that $10k mark (in the Northeast).
Since I haven't seen it specifically mentioned, the US Government requires EV batteries to be warrantied for a minimum of 8 years or 100k miles. Some OEM's choose to exceed the minimum requirement.
I don't think I'd have many concerns about longevity of a liquid cooled EV battery. The old stuff suffered primarily because it had improper cooling/thermal management.
Some of the more basic, older batteries can be repaired by swapping individual cells. But many latest gen EVs have battery cells that are essentially glued into the pack and cannot be removed without destruction.
Although they're less serviceable, these batteries are often composed of a handful of modules of cells that could theoretically be replaced more cheaply and easily than a full pack replacement.
