Thanks, I feel there is something missing when translating the stress tests made in that article to consumer peripherals. I get the impression that longevity is greatly sacrificed for short term performance in phones and laptops. But that is just me trying to explain why (my) phones and laptops loose their battery capacity so quickly.

Regarding Tesla supercharging I found this: https://www.teslarati.com/watch-tesla-battery-thermal-manage...

I also heard of issues of other cars (don't remember brand) who can't perform a supercharge - some driving - and then another supercharge because the batteries would overheat (still from the previous supercharge), preventing long trips.

Yea, it's quite possible that something changes at these (scary) high charge rates. Maybe charge efficiency takes a nosedive, or there are some other effects that are non-linear with charge rate. Thanks for the link.
