$this->bbcode_second_pass_quote('Cashmere', 'Y')es Please - I'll get back to the papers.
I need time to do the analysis.
$this->bbcode_second_pass_quote('', 'T')here is some degree of truth to the "peak lithium" theory, but only barely. There is enough lithium to go around. The only issue is finding enough of it concentrated in "economic" deposits, mostly in brine (salt) lakes and ponds.
You should know that this is pure bullshit. It's like saying, "there's 10 times more oil in the ground than has been pumped out."
The issue isn't how much lithium there is "to go around". There's only the actual amount you can dig out, and at what cost. You're making a tar sands argument here. And about the "finding" part - I'm not impressed with future maybes.
$this->bbcode_second_pass_quote('', 'C')urrently people do not even bother to recycle lithium and this gives you some indication of how cheap it is right now, compared with Ni-MH batteries which are mainly nickel, a metal costing an exorbitant $22,000 per metric ton
We don't recycle toilet paper either.
Has it even remotely occurred to you that we don't recycle lithium ions because it would be too difficult to pull it back out of the batteries? This isn't aluminum cans we're talking about here.
Saying that a lack of recycling means that we have plenty is horseshit.
Further, eve IF recycling is easy/possible, the only thing that matters is the cost of recycled lithium versus the cost of new stuff.
If the new stuff is cheaper, then we don't recycle.
Further, if you start putting the stuff in car batteries - several thousand times bigger than cell phones, then you radically change the amount required.
I'll get into the papers in a bit.
By the way, you're saying the main paper saying Lithium is short was written by a Li ion competitor? What's his name?
I would suggest that people are failing to think laterally with electric transport. All existing electric transport is powered conductively from the grid, not using batteries.
The combined issues of cost and poor power density are likely to make fully battery-electric vehicles impractical as a mass market solution.
More likely we will adopt a hybrid solution. This will begin with ICE/battery electric hybrids, but will eventually progress to electric roadway solutions. The real solution is to look for ways of getting direct electric power to vehicles. I would suggest some sort of electrified conduit system embedded within highways, with cars extending contacts into the conduit and earthing through the road.

$this->bbcode_second_pass_quote('mos6507', 'I')'m much more concerned about the rare elements used in thin-film and dye-sensitized solar panels since their whole business model is riding on the future availability of elements like indium, gallium, telluride, and ruthenium, not to mention the platinum in fuel cells. Unlike lithium, there may not be enough of these to even get to the initial scale out point to even think about how recycling would help.
By the time we need to worry about PM shortages,
thin film Silicon will probably be as cheap as they are now. Alternatives are easier to work w/, which is why they are being made first, but Silicon will probably catch up in terms of thin film costs over the next decade or two IMO.
