1-Million-Mile (1.8-million-kilometer) batteries

After 2 million kilometers (1.25 million miles), CATL’s EV batteries retained about 400 km (250 mi) of range. Competitor cells, on the other hand, retained considerably less, at around 350 km (218 mi) and less.

The data is based on 12 electric vehicles, 100 sample batteries, and real-world applications across four major cities in China. You can see in the chart from Morgan Stanley Research that Models 11 and 12, which use CATL batteries, exhibit considerably slower degradation than the other suppliers.

What leads you to believe that CATL has been unsuccessful at achieving a 1 million mile battery?
