I hope electric cars get longer-lasting batteries, because I can't afford a new one and I wonder when buying a ten year old EV, if the battery will be performing at reduced capacity once ten years old.
Maybe 2030 battery tech will be good for 20 years by then.

We think a lot alike
Battery life is more about discharge cycles than years you would expect 500-1000 discharge cycles before capacity drops to 50% on older batteries, newer should be better but obviously they have not been around long enough to know for sure.
24kWh Nissan Leaf battery is about 50%capacity after 100k miles, Tesla Model S being bigger car uses a bit more electricity but I don't think the difference is huge so say 70kWh is almost 3 times larger so could do 3 times as many miles for the same number of discharge cycles or 100kWh battery 4 times more and Teslas batteries may be better, lasting more cycles.
