I think we are both saying the same thing, you are just getting more into the details. The faster chargers generate more heat which is what causes that loss in capacity. My statement was based on the SAE EV Engineering program which presented several studies showcasing number of cycles to 10% loss in capacity and when going from .5C to 1C the cycles went from 5000 to 200 cycles.

The faster a battery is charged though the greater the capacity loss over time. I am curious how that issue can be addressed.

After doing some more digging it looks like the study I mentioned used Nissan Leafs which don't have a robust thermal management system for their batteries (they are air cooled) so newer EVs probably perform much better.
