"It is reported that the total amount of lithium reserves in the oceans is approximately 2.6 × 10^11 tons."
Harvesting it, of course, is not all that viable. We are starting with strip mining "lithium lakes" that dried up and made concentrated deposits. We start with the lazy sources, first. Those areas likely have a lot of salts in them, but we're only interested in one of the salts.
However, there are other chemicals needed to make the hardware, which are much harder to come by.
The Chinese are pushing Lithium Iron Phosphate. And Tesla is onboard with it. It's quite possible that every Model 3 now, ships with Lithium Iron Phosphate packs. Some of the older (more expensive) models, would continue to have Cobalt-based ones.
Cobalt and nickel are expensive.
I didn't know things were this bad, that the cells were roughly the same price ? How is that possible ?
"A second automotive OEM echoed that comment, "LFP batteries will be there for entry level vehicles, but not adopted for premium cars"."
*******And some of the recent astronomy articles on ars, hint at where heavy elements come from. Supernovas are a good source.
But we don't normally sit just outside a supernova, with a catchers mitt, because we'd be fried instantly by the infrared. A safe distance from a supernova, is a long long way.
"Earth would have to be at least 50 light-years away from the exploding star."
And we can't even manage to go the 4 light-years to the "neighbours".
"Proxima Centauri is slightly closer at 4.25 light years"
