The lie that electric vehicles are better for the environment than internal combustion needs to stop. Lithium batteries will pollute the world. We will exploit impoverished counties and extract their lithium reserves while destroying their environments. We will not clean up when we finish. Lithium batteries will pollute our water supplies here at home when they aren't properly disposed. This is a giant environmental…
> We need widespread renewable electricity generation first anyway. Otherwise our electric cars will be running on coal. Even this is preferable to internal combustion engines. ICEs really aren’t very efficient, and electric car is easily 3x more energy efficient than an ICE. Which means that’s even if you include transmission losses and heat losses at a coal power station, you’re still ahead. Because of coal power s…

> Lithium is a mine once, use forever resource. It's an element. It will cost energy to recycle it ... and human labor, and other chemicals. I'm not sure if you read the article, but it claims that recycling is still a somewhat tenuous economic proposition vs digging more out of the ground. This is especially true given the glut of lithium, while cobalt and other rare minerals are slowly being phased out of battery d…
The second company described in the article claims to recycle using nothing but catalysts, and simply grinds up the used batteries in a giant vat before transportation (rendering them inert, and easier to safely move). It sounds like their main problem at this point is continuing to scale the business to meet supply (they are already the largest lithium recycler in the US), and that the challenges there are logical,…
And if a mine can be automated to yield orders of magnitude more material than recycling for the same labor costs, you would need some other financial incentive (government subsidies, backroll by Tesla for marketing purposes) to make it viable.

Tesla's previous CTO and Co-founder, JB Straubel (who spent 15 years at Tesla), left to found Redwood Materials [1] (which intends to scale up battery recycling processes). Fortum, a Finnish clean energy firm (correction provided by @Sharlin), has reached an 80% recycling rate as of 2019 [2]. It's always going to be cheaper to pour end of life cells into a remanufacturing process than to extract raw lithium from brin…
> It's always going to be cheaper to pour end of life cells into a remanufacturing process than to extract raw lithium from brine ponds, so it makes economic sense to do the R&D to do so. This is a major point to assume away.
Aluminum and iron recycling is viable because they are elements in their own right.

This is precisely the literary slight of hand I was talking about! Similar to Musk's hilarious dismissal of hydrogen technology. Hydrogen will obviously in time become the ideal source of energy for electric aircraft and electric long haul trucks.
Has hydrogen storage been solved? How big would a hydrogen tank have to be to power a plane for more than an hour? And what is the conversion rate of hydrogen to electricity?
Efficiency depends on fuel cell type and operating conditions and such, but I think it’s generally pretty high for the useful life of the catalyst material. (The catalyst is another materials challenge itself, since I think most of the good materials are super expensive like Pt/Pd alloys, and they’re vulnerable to carbon monoxide poisoning)
Edit: this DOE program page has some good detailed discussion of the current status, including on compressed liquid/gas storage systems, which I’m not as familiar with: https://www.energy.gov/eere/fuelcells/hydrogen-storage-curre...

I'm not sure that's an accurate assessment. 1. Reduced dependency on oil = less money in oil = less money for a lot of countries that historically act quite poorly on the world stage. 2. 100% better for global warming than combustion cars. 3. Is mining lithium & disposing on lithium batteries incorrectly worse for the environment than oil manufacturing, production & transport? I don't know 100% but the massive oil sp…
Are lithium batteries ever used at grid-scale? I though the point was that the high energy-density was convenient for mobility, but poor on most other metrics, including manufacturing complexity, stability, and safety. Grid-scale wouldn't need to care so much about energy density versus stability and maintenance, in which case lead-acid, or compressed-gas storage should shine.

Uranium isn't necessary. A breeder reactor could manufacture plutonium, or a thorium fueled design could be used. Nuclear power isn't constrained by fuel scarcity at all. If anything, we have too much fissionable material.
That is, how a transition to these alternatives would conceivably integrate in and have an impact on larger market dynamics, and they way they might be either furthered or impeded by local, regional or geo-political dynamics.

That's right, it's better. The old mantra "reduce, re-use, recycle" is in that order because that's the order of "greenness". Recycling should be the last resort.
Re-use of a battery is fine, but it's a stop-gap. The battery will eventually reach a state of health where it isn't useful in any application anymore, so recycling is still necessary. The "re-use" step just delays that a bit.
Batteries are a way too important source of valuable materials to not be recycled.

Yes, John McCarthy hasn't updated his web page in a while, because he's been dead for nine years. Have some respect for the man who invented Garbage Collection!
But more importantly, do you think a lot of uranium has disappeared in the last 13 years? Has the use of uranium increased by an order of magnitude in the last 13 years? Have we forgotten how to extract uranium from low grade ore in the last 13 years? No?! Then how the hell is the age of this web site (13 years) or Bernard Cohen's book (35 years) even relevant?
> My comment referred to commercial viability.
Don't move the goal posts! You specifically wrote "Uranium is finite", and the counter point is that it is practically infinite. As McCarthy points out, this doesn't even depend on seawater extraction, because low grade uranium ores (phosphate ores, later Conway granites) are plentiful.
