It may have changed in recent years but several years ago when I was more into EVs it was a reasonable concern. But I do somewhat question the legitimacy of this seeing as how quickly small electronics Lithium batteries degrade.

There are now soooo many studies out showing that capacity in EVs drops significantly slower than ever expected. An EV that is used "normal" is basically best-case for Li-Ion batteries. You are charging the car once to twice a week and then you are charging it slowly over night or at your office, only using fast-charging when you are on roadtrips. You rarely drop your battery percentage below 30% and a lot of cars also dont go higher than 90% capacity without you explicitly activating it

Can you please send a source for the studies?

Do you mean phone batteries? Cause they are often cycled at least once a day. If you drive your ev for 500km a day, yes, don't expect it to last five years. But I would think an ICE car would handle that either.

Electronics batteries degrade within a couple years even with very few cycles in my experience.
