"The process starts with old batteries being separated and burned to strip away non-metal components. What's left gets crushed into something called black mass. This is essentially a powder packed with recoverable metals. From there, a water-based chemical treatment called hydrometallurgy pulls the lithium out. One clever distinction in this new process is that the recovered lithium hydroxide actually replaces a chemical traditionally used during refining. This cuts the carbon footprint by about 40% compared to older methods."

Article also said that previous methods got about 45% of the lithium from recycling.

Jerry Rigs Everything Video about lithium recycling to black mass.

Recycled lithium uses 70% less energy than virgin freshly mined lithium, and lithium, like aluminum, in infinitely recyclable.

Assholes like Jeremy Clarkson don't get this.

Ok it needs to be said. The smart play is to have governments to subsidize this process and build up the raw inventory for lithium. That way, ie (US) could have tons and tons of raw lithium without having to mine it.

[–] besmtt@lemmy.world 23 points 2 weeks ago (3 children)

Wouldn't it be smarter to use old EV batteries for grid storage?

[–] FederatedFreedom1981@lemmy.ca 49 points 2 weeks ago (1 children)

Why not both? Downcycle the old EV batteries for grid storage, then when they reach the end of useful life, recycle them. We need to resurrect the first 2 R's (Reduce, Reuse) to be able to survive on this planet.

[–] Omgpwnies@lemmy.world 12 points 2 weeks ago (1 children)

They are listed in order of importance.. reduce first, if you can't, then reuse. If you can't reuse, then recycle.

Problem is, we saw "recycle" and thougt "infinite resources" and ditched the other two.. turns out that most things cant really be recycled, so now it's just landfill all the way

[–] FederatedFreedom1981@lemmy.ca 12 points 2 weeks ago

I wish I could remember where I read it, but the focus on just Recycle was encouraged as the main narrative by corporations which didn't want to give up the myth of endless growth.

[–] DarrinBrunner@lemmy.world 34 points 2 weeks ago (1 children)

The batteries don't last forever, eventually, they need to be dealt with somehow.

[–] Omgpwnies@lemmy.world 9 points 2 weeks ago

Also grid storage doesn't have the sort of deep, rapid discharge/charge cycles that EVs go through. Once an EV battery is no good in the car, it still has about 80% of it's useable capacity left. Meaning, there will always be a need for "new" EV batteries, but grid storage would saturate and leave surplus batteries. Not to mention, as the grid storage batteries fall out of their useful life for that purpose, they can be recycled into new EV batteries and begin the cycle anew.

[–] SaveTheTuaHawk@lemmy.ca 5 points 2 weeks ago

Not if they are not holding energy any more.

[–] LastYearsIrritant@sopuli.xyz 16 points 2 weeks ago (5 children)

That's great and all, but not all batteries need lithium. When another battery technology gets mature enough to surpass lithium based batteries, then we'll still be stuck on old tech cause the government is subsiding it.

This also reduces the incentive for making more lithium efficient batteries.

Subsidies can help, but they need to be more generalized so they don't create issues moving past current tech. Heck, look at how much trouble we're having getting past oil, that's a perfect example.

[–] AnyOldName3@lemmy.world 13 points 2 weeks ago (5 children)

Under modern physics, Lithium is pretty much the best possible chemical to build batteries out of. Anything else that might be better won't be a chemical battery, and it's not like there's any reason to suspect some new magic thing will be created like a pocket-size fusion reactor that will make chemical batteries totally obsolete any time soon. Decades more of lithium batteries being relevant are as close to guaranteed as can be.

[–] nyan@lemmy.cafe 12 points 2 weeks ago (1 children)

Lithium is pretty much the best possible chemical to build batteries out of.

Depends on how you define "best". Likely the highest possible short-term energy density, yes, but that isn't the only thing we might want out of a battery. "Doesn't catch fire" is one of the areas where the highest-energy lithium battery chemistries are far from the best, for instance.

Sodium batteries? Of course it depends on their use a bit.

[–] ayyy@sh.itjust.works 6 points 2 weeks ago (5 children)

Those are not “better” batteries chemically or electrically. They are just cheaper and don’t use lithium which is considered a feature.

[–] rbos@lemmy.ca 8 points 2 weeks ago (5 children)

Cheaper is a kind of better.

That's great for grid storage. Maybe one day for even EV use, emphasis on maybe. But you'll never have a cell phone with a sodium battery

Kickstarting new infrastructure is one place government money tends to work well. You can always phase out the subsidies and there is an argument that battery tech benefited from a feedback loop (used in phones until infra and tech was cheap enough for cars+) and something needs to kickstart that for their recycling, government stepping in to start that loop isn't uncommon or as terrible as you seem to be making it out

We recover 99% of lead from car batteries. The same lead is used over and over.

[–] BygoneNeutrino@lemmy.world 5 points 2 weeks ago (1 children)

Lead is much easier to purify than lithium.

You know what the richest ore for finding metals for new batteries is? Old batteries. Same applies to solar panels. This is great to see.

Yeah ive played rimworld too.

[–] SkunkWorkz@lemmy.world 7 points 2 weeks ago (2 children)

Also for aluminum it’s cheaper to recycle aluminum than to produce it from raw ore.

I believe 10% of a lithium battery is lithium. I mean, it's impressive and I love a closed loop for the life of any component, but this doesn't really solve our need for more lithium. Reduce it yes, but not end the requirement for more extraction

[–] sunbeam60@feddit.uk 9 points 2 weeks ago (2 children)

But I presume a new battery also only need 10% lithium?

[–] Vetis@sh.itjust.works 10 points 2 weeks ago (1 children)

Right, I don't understand their point. Recycling 90% of a battery is still 90% of a new battery.

Exactly.

The whole reason why lithium is such a good material for cathodes in car batteries is because of its very low mass per cation. So for a Lithium Iron Phosphate battery, the the cathode material is LiFePO4, where the Lithium itself is only 4.4% of the overall mass of the cathode.

So it's important to remember that although the lithium constitutes a small amount of the total mass of a battery, that swings both ways so that not much is actually needed to build the next battery out of recycled materials.

[–] SaveTheTuaHawk@lemmy.ca 6 points 2 weeks ago

Any metal in a car needs mining and extraction.

You would not believe how inefficient mining is for platinum and rhodium in ICE catalytic convertors. The oil and gas industry has really drilled into the heads of people that lithium is evil.

I just want the fucking oil mafia to burn at sun’s temperature. They are such a fucking obstacle and disgrace to humanity’s development. Same goes for the big pharma. All the suffering just because of greed for a piece of paper with £/₹/$/€ on it.

Ok angry rant over.

Capitalism rewards profit. Imagine basing all aspects of life on profit making. Of course human needs, interests, environment health etc. take up a side-role in such a system.

Lithium recycling has never been the problem. The problem is most EVs are new, and people aren't buying enough of them, so there isn't enough capacity of old batteries in the system yet for business to profit from building the plants to do the recycling. And now some stupid orange asshole has been sabotaging production, so we're not going to hit that tipping point for decades.

I remember reading another article that said that their incinerated sewage waste had more gold per ton than their highest yielding mines.

[–] DarrinBrunner@lemmy.world 9 points 2 weeks ago

Terrific. But, I suppose it won't happen at scale until it's cheaper than mining.

Because money is everything, and our environment is replaceable. /s

This is going to make it even less of a reason for companies to invest in sodium batteries
