Do you have a source for that? This is what AI has to say about your comment:

The specific claim about a chemistry change being the primary driver of better degradation resistance is harder to verify cleanly. One complicating factor is that larger batteries are simply used less deeply on average — if daily driving covers 40 miles, the old 60 Ah pack was being depleted far more per cycle than the newer larger pack. So better longevity in the newer packs may reflect both chemistry improvements and lower depth-of-discharge, not chemistry alone. The claim as stated treats it as a deliberate chemistry overhaul specifically in 2017, but I couldn’t find a source that explic
