For my EV, which I charge about once a week on average, with 4,000 cycles that means about 77 years!! That's a huge deal. CATL quoted 10k cycle battery too. Wow. Very cool. Yeah energy density and operating profile and all that. But color me impressed.

It’s not only about longevity in time but also in terms of miles.

For heavy users and given a standard range of 250+ miles, we are talking about a longevity of 1 000 000 miles. I never had a car with more than 200.000km (120 000 miles).

If you look through second-hand car listings in Europe, >400,000km is not that usual to see. In places where cars are relatively expensive, folks keep them running forever...

That said, a million miles is probably enough for anyone :D
