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).

There was a Korean guy who drove an Ioniq, on its original battery, over 660,000km. Basically going up and down the country every day for work.
