New battery chemistry tweak could double EV range

1000 cycles in a 400 miles range electric car (Tesla sells one already, without this fancy battery) is 400,000 miles. Since this battery chemistry will enable longer range, let’s call it 500-600 miles, or 500,000 to 600,000 miles. That’s pretty high.

Also, it’s not true that lithium battery recycling is merely lab scale. Pilot plants, like those operated by Li-Cycle in Toronto, are well beyond lab scale. They’re also in the process of building commercial scale facilities as we speak, not “5-10 years best-case.”

Your argument may have been valid 5-10 years ago but isn’t today.

I'm not sure what counts as a cycle? Does say running it to 70% remaining for 10 days then recharge at night count as 10 cycles?

If so than the actual total lifetime max miles would be way shorter for most city people. Unless IDK if Tesla has a smart setting on their charger or something to maximize cycles at the risk of running out of range.

A full cycle means 0-100% (or roughly that). Charging 30% of your battery capacity counts as just 30% of a cycle in this case. And yeah, electric cars generally do daily cycling up to 80% capacity to extend capacity with 100% capacity being used for long trips.
