Tesla: Battery Capacity Degradation Averages 12% After 200,000 Miles
The performance of newer chemistries will be revealed once there will be more data.
In the future, Tesla intends to present more data related to battery capacity retention. There are new EVs (Model 3/Model Y), and new battery types (cell formats as well as chemistry types), which might have noticeably different results.
"Performance of newer chemistries (not yet shown here) can vary and we plan to expand disclosure once we have sufficient data."
We guess, that the LFP lithium-ion battery chemistry would be the top contender in terms of longevity, compared to the high energy-dense NCA and NCM families.

The initial Nissan Leaf had poor battery management and did degrade to 70%. New EV's have improved chemistry and battery management and around 10% loss is expected of car life
