This is good news! I hope it works and goes into full production.
I know battery replacements are not cheap. But I wonder if in a few year’s time we’ll see battery replacements with this new technology (assuming it actually does go to production).
The pace of change in this space is one reason we have not bought an EV yet. (The other is that, honestly, we don’t need a new car just yet anyway). What would the resale value of today’s EV be in 4-5 years if new models can charge in 10 minutes?
