I've been thinking about this topic a lot lately. The one-million mile battery technology is not nearly as important as the 400 volt vs 800 volt architecture.
Current battery tech from LG Chem that the MME uses will last between 300,000 (75kWh) to 500,000 (99kWh) miles before its useful life in the vehicle has elapsed. Once the batteries are down to 70% of their original capacity, they will be retired to a second life as stationary storage for another 20 years or recycled. Functionally, I don't think many of us are going to be able to take advantage of that many miles so a half-million miles or one-million miles are the same thing.
Going from 400V to 800V has implications for charging time with a reduction from 40-45 minutes to approximately 20 minutes to get 80% SoC. Charging that fast to gain 200+ freeway miles starts to change the paradigm from taking a technological break (car needs to recharge) to a biological break (bladder relief).
As far as 500-600 mile range goes, outside of a tow vehicle I really don't see it happening. But I could easily be convinced otherwise.
