This is quite exciting times we live in. I am hoping the price premium is minimal.

Of course, as with any new tech it still has to happen. We can hope it will.

I thought tesla claimed they had a 1 million mile battery last year.
The problem is do people want to pay for 600 miles of range?
Today 600 miles of range means the car would literally have a ton of batteries in it.
If I can get a leaf plus battery that means I can charge about once or twice per week.
If I had a 600 mile battery, that's 2 or 3 charges a month.

People are willing to pay for a guaranteed 350-400 miles of range, which currently requires 500-600 miles of BEV range when new, if they need to take long trips. But not if it costs $50k or more.

I read the density should increase by a factor of 2x so cut that to weight by half.

600 mile range in a car might seem excessive however when you are looking at large vehicles or towing... this just starts to make them practical.

Great to go EV in an econobox but real savings will be in the large SUVs and trucks.

Doubling density seems reasonable.
But does it scale?
For example if density doubles how much does price price increase?
If it's a 10 or 20% that's good for evetything if it increases prices 50% to double that's still good but only for mobile phones, laptops cordless tools, not so good for cars and trucks.

Price stays about the same per kg. Halves per kWh. Putin will be pissed, don't tell him.

According to who?
Putin is always pissed off about something, nothing new there.

I would love to have a 120kwh, 900lb leaf battery that costs the same as a 62kwh battery but it sounds too good to be true if happening any time soon.

Must really suck to work for him.

Look at past battery costs and densities...
