I can't speak for other EVs, but Samsung (who makes the battery in my 94aH i3) says the battery in the 94aH battery in the i3 will be end of life (80% of original capacity) at an average of 526,000 miles. That seems sufficient to me.

Ours is currently at 80,000 miles, and has lost 3% of original capacity according to the cluster battery test (battery kappa max). Most of that happened when the car was fresh off the lot, as is typical.
