The following submission statement was provided by /u/chrisdh79:
From the article: A recycling method developed by Karlsruhe Institute of Technology (KIT) recovers up to 70% of lithium from battery waste without corrosive chemicals, high temperatures, and prior sorting of materials being required. The method combines mechanical processes with chemical reactions and enables inexpensive, energy-efficient, and environmentally compatible recycling of any type of lithium-ion battery. The results are reported in Communications Chemistry.
Lithium-ion batteries are omnipresent in our life. They are not only used for the wireless power supply of notebooks, smartphones, toys, remote controls, and other small devices, but also are the most important energy storage systems for the rapidly growing electric mobility sector. Increasing use of these batteries eventually results in the need for economically and ecologically sustainable recycling methods.
Presently, mainly nickel and cobalt, copper and aluminum, as well as steel are recovered from battery waste for reuse. Lithium recovery still is expensive and hardly profitable. Existing recovery methods mostly are of metallurgical character and consume a lot of energy and/or produce hazardous by-products. In contrast to this, mechanochemical approaches based on mechanical processes to induce chemical reactions promise to reach a higher yield and sustainability with a smaller expenditure.

Lithium reminds me of the story of aluminum, which too was only available via destructive and expensive bauxite mining in third world countries. Now most all aluminum is sourced via recycling and makes for much cheaper manufacturing than sourcing from raw materials like we did decades ago.

The ocean is the biggest practical source but desalination is expensive. They don't really mine it, they use desert floors where old salt water dried up.

Can this be combined with something else to increase the total recovery? 70% in an efficient process is good, but losing 30% each cycle isn't. I'm assuming then a secondary processing with more energy intensive means will recover most of the remaining 30%, but costing approximately 70% less to process due to decreased volume?

> we need to move away from lithium batteries.
Why?
The dominant lithium producer is Australia, which produces via standard hard-rock mining, so producing most lithium is no more harmful than any other developed-world mine.
Compared to the 7,500 Mt of coal mined per year and 4,200 Mt of oil extracted per year, mining 0.1Mt of lithium is not an urgent environmental or social issue.
(In case you were thinking about cobalt, LFP batteries use no cobalt and will reach 50% market share in the next few years.)

That’s cool :) but to play Devils Advocate here, what incentive would the auto manufacturers have to switch to this method? I’m assuming 100% of EVs right now will come off the production line with brand new batteries, especially Teslas since they have a deal with Panasonic. How many will have to be manufactured with 100% mined lithium before we can close this loop? Wouldn’t everyone need to own at least one EV before this is possible?
Also, the cost and energy required to recycle these things. Who’s paying for it? And once enough lithium is mined to have a closed loop, how will we offset the damage and pollution caused by raw mining and how long will that take?
Genuine questions, not trying to sound like a bad guy.

Too many people in the desert using too much water. Farming is the biggest culprit. A long time ago they made a plan to distribute the water but they gave away too much even then. The problem has become worse because there hasn't been enough rain in the region for, like, a decade. Now unless people agree to stop using water the place could become uninhabitable, at least for the number of people who want to live there.

Lithium is lithium. As recycled lithium comes onto the market there will be increasing opportunity for battery manufacturers to use it.
There are already robust salvage markets for copper, steel, aluminum and other valuable, recyclable metals. Auto manufacturers do not necessarily have to do this themselves.
Yes it will cost energy to recycle lithium batteries, and that cost is expected to be small compared to the value of the recovered material.

Another fun story, electrical discharge machining or EDM was independently developed in the USSR and USA at the same time, but for extremely different reasons.
In the USSR they had an abundance of tungsten which is incredibly hard to machine using cutting tools, being as cutting tools are made of softer or equally hard materials most notably tungsten carbide. To make use of the tungsten, EDM was the only process available. In turn many structures and aircraft from the period have parts that would be extremely financially irresponsible to produce in the USA.
However the USA at the time had developed aluminum to build lightweight structures and products across basically every industry and the only problem they faced was that their tools kept breaking inside the relatively soft metal. The solution for this issue was using EDM to burn the broken tool bits out of the workpiece.
Now EDM is used for many purposes beyond these two, and you'd piss off an EDM machinist if you asked them to stop what they were doing to get a broken tap out of something.

I get why people are skeptical about switching vehicles to electric. There are a lot of negatives that people tend to over look just because they want to look cool in a Tesla and brag about helping the environment. But the fact is we can solve most of the problems electric vehicles have with some good old fashioned R&D. As much as oil companies try to look like they can do the same, it's just not possible. Gas cars just can't fix any of their remaining issues.

Govts would have to mandate all products contain a mix of recycled and aluminum. Probably coax with tax breaks then it becomes something you can build a business on and then it gets created.

It depends on the future of course, but like how lithium first showed up in phones, then laptops, then larger and larger things - if something comes out to replace lithium in certain use cases, say iron batteries for grid storage, then all that lithium can be recycled back into the mix.
Or if there's an expensive but newer medium that starts going in phones, then tablets, then laptops, then power tools, and so on - all those batteries get recycled back into the lithium pool

Now, if you consider evaporating water off of brine in a high altitude, uninhabitable desert as environmentally destructive, and would use the same term for destroying forests with much bio-diversity, than the term is meaningless.
Point being, this is where a large chunk of the worlds lithium comes from and it's a desert, and I would consider it non-destructive.

The batteries will always be new. The lithium used to make those batteries will either come from mines, the sea, or recycling.
It's the same with aluminum cans. Every coke can is new but the aluminum in that can might have been mined 50 years ago or a few months ago.
> How many will have to be manufactured with 100% mined lithium before we can close this loop? Wouldn’t everyone need to own at least one EV before this is possible?
The loop will never be closed. Again using aluminum as the example. Despite how easy it is to recycle, new aluminum is always needed. Recycling just greatly reduces how much mining is needed.
> Also, the cost and energy required to recycle these things. Who’s paying for it?
The people who need to buy lithium. They will either pay for the cost to mine it or they will pay the cost to recycle it.
> And once enough lithium is mined to have a closed loop, how will we offset the damage and pollution caused by raw mining and how long will that take?
Mining lithium really isn't that bad and you have to contrast it with oil extraction as that's what EVs are replacing. Oil extraction and subsequent burning of oil is so bad we might have completely fucked ourselves for centuries. People are completely numb to how insanely dirty fossil fuels are as it's all they've ever known.

As I said, it depend entirely on the products in question as well as the market. Aluminum is valuable enough to more than pay for salvaging costs for most products that contain a meaningful amount.
Glass meanwhile is currently not cost-effective because the value of salvaged glass has recently fallen below the salvaging cost, even though glass recycling was quite cost-effective in the past. The market is just as important as anything else here.
Solar panels are not cost effective at all to salvage as their components are not particularly valuable but are quite costly to salvage from the panels. Thus they are piling up in landfills wherever there are no regulations that require proper recycling.
