New large-scale mining in the US?

You're funny.
The second largest lithium mine in the world is in the US.Thacker Pass is located in Nevada and may be on top of the largest lithium deposit in the world. It was discovered this year. This is in addition to the Silver Peak mine. Also, a large scale mining operation is coming online in the Salton Sea.

The problem with the argument is value: Modern EVs are nowhere near as superior to Modern ICE cars as early cars were to horses. The EV today is a shiny horse designed to act like a traditional car. Trying to make them usable for unstructured, long-distance journeys for holidays or business is making them affordable but that's what people demand (I don't blame them) if it's marketed as a replacement for their 10yo ICE car that's running perfectly fine and will likely be fine for at least another 10 years.
And what will there be after 10 years?

My crystal ball is a little fuzzy.
Better clean energy storage for cars hopefully. If any of the advanced battery technologies pan out, that can be used or something else.
There are fields and fields of early EV's rotting (and unlikely to be easily recycled) in China so jumping in early with a total commitment to the EV might not be the wise thing to do.

Large battery packs that power electric vehicles may contain several thousand cells grouped in modules. The packs also include sensors, safety devices, and circuitry that controls battery operation, all of which add yet another layer of complexity and additional costs to dismantling and recycling.
All these battery components and materials need to be dealt with by a recycler to get at the valuable metals and other materials. In stark contrast, lead-acid car batteries are easily disassembled, and the lead, which accounts for about 60% of a battery’s weight, can be separated quickly from the other components. As a result, nearly 100% of the lead in these batteries is recycled in the US, far surpassing recycling rates for glass, paper, and other materials.

Just wondering.. . does anyone know why are EV batteries made up of thousands of tiny cells? Lead-acid batteries of similar capacity are made up of individual cells weighing 100kg each.
I thought the extra weight of the casings would be something to avoid.

I imagine larger cells are difficult to keep cool, and likely detonate spectacularly.

Just a guess.

BTW, I bought some of these at Amazon:

I assumed they were lying about the capacity, but if they really were 10Ah cells, I had a really good product idea that would make use of them.

Tested out at 1 Ah.

I don't trust any of the new-fangled tech wrt batteries and "sustainable" power.

Get off my lawn.

The most dubious lithium batteries I ever bought went under the trade-name "UltraFire". I note that "UltraFire" is now the trade-name of a specialist fire extinguisher for Lithium batteries.

It's like they created their own new highly-profitable market.

Crony capitalism at its best.

Electric Cars were all the rage a century ago. I wonder why they never caught on and were out of existence by the 1940s... I once saw the remains of one of their batteries in the 60's. Basically, it was a suitcase sized box filled with the remains of what looked like #6 dry cell batteries that apparently fit under the bench seat. They sure didn't look like they were rechargeable.

A $60K battery for a $50K car...

Hi,

Yeah, I am still waiting to see what new battery types come out of China and other places for this application.
How long is it going to take. Lots of claims of lower prices and longer drive distances. But when.

They died out because they were led acid and there was not that much power generated.
