    It really should not be surprising that we can get very high recovery percentages from batteries -- we do not mine elemental lithium, so the processes we use for extraction are already designed to extract lithium from fairly low-purity sources. In contrast, lithium batteries are an incredibly high-purity source of lithium. The main question is when it will become cost-effective to create recycling pipelines.

    Lead acid batteries had a similar trajectory and modern lead acid batteries are effectively 100% recycled.

      U.S. lead acid baterries recycling has been outsourced.

      " As the United States tightened regulations on lead processing to protect Americans over the past three decades, finding domestic lead became a challenge. So the auto industry looked overseas to supplement its supply. In doing so, car and battery manufacturers pushed the health consequences of lead recycling onto countries where enforcement is lax, testing is rare and workers are desperate for jobs. "

      Plenty of substances we don't mine elementally are not worth recycling. The main advantage with lithium is it tends to go into large volumes of standardised chemistries.

    according to https://x.com/Mith_/status/2041911606213537971

    > The industry standard for the recovery of lithium (remember there is a difference between recovery and extraction) is 90%, with some platforms now achieving 95%+ like those that use carbonation.

    What about the cost? In China, most used batteries are just burned and buried, so the recycling cost is very low.
  • justnoice 29 minutes ago
    The 90% recovery rate is not groundbreaking by itself. The real value is lower contamination and emissions—but it still needs to prove cost-effective at industrial scale.

    So long or short Lithium?
  • simondotau 1 hour ago
    This article is poor, because lithium is just one part of the value contained within EV batteries. Far more valuable is any nickel, cobalt and graphite. Equally valuable is any copper and aluminium. Unless you're effectively recycling a significant number of the major materials, it's not enough.

    Furthermore, it's not a remarkable achievement. By contrast to this headline, Redwood Materials claims "Redwood’s technology can recover, on average, more than 95% of materials like nickel, cobalt, copper, aluminum, lithium and graphite in a lithium-ion battery."[0]

    I'm so tired of reading articles written by LLM. There are several sites that just ingest material (like studies) and crap out low-effort LLM articles.

      I used to enjoy watching smaller youtubers, but everytime I've given one a chance lately it has been unbearably clear that it was written by an llm. Supposedly people have ingested so much llm writing that they've naturally started writing in a similar style.

    The key point will be the energy inputs, and catalyst or other process input losses. Not the % recovery, its more recovery at an economically viable cost

    Many processes could recover the inputs. Some are tremendously polluting. Cheap methods to recover lead from older lead-acid car batteries would be an example, or the way scavengers burn plastic insulation of recovered copper wiring.

    TL;DR exernalities and economics and pollution drive recycling issues, not % recovery at this point. We know how to recover a lot of the inputs. Knowing how to industrialise and scale it up is what counts.

    John McCarthy (of LISP fame) was an (in)famous curmudgeon on USENET, frequently used to say future generations will thank us for making giant collections in the ground of highly valuable recoverable industrial inputs, what we call "rubbish dumps" -He was only partially less wrong, but had a point to make about the cost of inputs to industry vs raw mining costs. If we do come up with a process to strip mine rubbish dumps and send feedstocks in the appropriate directions there's a lot there. Complex plastics, Metals, Organics, Acids, Methane Gas, you-name-it. We already collect and harvest the methane to drive other dump works, the idea of mining the materials isn't "wrong" as much as insufficiently economic right now against raw material sources.

    why bother? japan hate EV
    • mc3301 1 hour ago
      I used to follow it closely and be in the industry, but it still seems like Japan is gonna be the last "mostly ICE cars" of the developed countries.

      Which is a shame, because it has a perfect combination of short-range needs (I mean, look at kei-cars), tons of wonderful places to hang out while charging (toll-way rest areas are so good), rare sub-freezing temperatures in most of the country, mandatory vehicle inspections (which could collect great safety data as well as preventative maintenance), general love of new cars and brand loyalty, lack of political or individual divide of "big gas trucks are manly", mobile-power-station earthquake preparedness (a nice bonus), generally cooperative nation-wide infrastructure...

      I guess we just have to hope the main automakers can hold on long enough for solid-state batteries and move faster than a snail's pace when it does.

        Why cars though I think people are still stuck with the cars mindset. But with electric we can get smaller ebikes/pods for individuals instead of cars

        If you live in Tokyo or Osaka you really shouldn’t own a car
        • klempner 14 minutes ago
          And one of the points that's a little more obvious living here: Japan is a remarkably car centric culture. Not quite to the extent of America, but in much of the country you really do need a car.

          If anything the main exceptions to that are exactly the places tourists are most likely to go.

        Isn't the reason they are so slow to adapt them that they have not enough electricity?

        In your opinion/experience, why is it that they aren't switching?
        • mc3301 3 minutes ago
          Probably a mix between oil-ties and the fact that decisions in Japan are made slowly.

          Edit: I also think there's a fear of this: wide acceptance of EVs open the door to BYD (or similar) huge takeover of the car market.

        • chubs 52 minutes ago
          I have a theory: Japanese car's have excellent reliability, their interiors and design are lacking. If every car in the world is an EV, which due to their relative simplicity tend to be reliable, what remaining unique selling points does eg a toyota have?
      • cyberax 53 minutes ago
        Solid-state batteries are facing production hell now, with lots of issues cropping up when tested at large-scale in real devices.

        So they are not expected in meaningful quantities until the early 2030-s.

        And the LFP chemistry has now advanced so much that solid-state batteries might not even matter anymore, except for some niche uses like aviation/drones.

      It is curious - you would think they would love it? But they don't - is it simply the case of the Chinese beating them - stubbornness and pride? Or is there something more going on?

      Toyota was seemingly decades ahead at one point with their hybrid cars; but now they have resigned to a defensive position compared to Tesla, Chinese automakers, even the European ones.

        > you would think they would love it?

        no. i just found it funny.

        > Or is there something more going on?

        I remember BYD actually had to design models specifically tailored to the Japanese market (k-car)—their preferences are honestly so bizarre. I think a lot of this comes down to their national character. Once external momentum fades—like the industrial transfers from the US—they seem to lose the drive for technological innovation. They just cling to whatever they already have and refuse to adapt to global shifts.People in Japan are still using Yahoo and fax machines(not to mention their own bizarrely proprietary text editors,Hidemaru/SAKURA editor, to compare, in china, it's also vscode).

        Toyota is still digging its heels in on gas-powered cars, even though the fact that Tesla used Japanese batteries in its early days proves Japan was once ahead of the curve.but they always seem to retreat right back into their comfort zone after a brief flash of brilliance, watching the rest of the world race ahead while they continue living in the past.

        • hnav 1 hour ago
          That's probably a good thing, the world needs appliance-like cars for markets where EV charging isn't there yet.

          Meanwhile Toyota is #1, moving millions of units, something like half of them are electrified in most markets. A 2026 Camry, for $30k, gives the buyer a low-TCO, value retaining, 50mpg, 230hp appliance of a car. That's a rarity.

      • BLKNSLVR 41 minutes ago
        Toyota's first Prius (hybrid) came out in 1997 and Nissan's first Leaf (full electric) in 2010. Both Japanese, both ahead of the curve, now way behind it.

        It is an interesting situation.

        Anecdote: I have a 2014 Leaf, purchased a couple of years ago as the first foray into EVs. It's a great little car, perfect for the daily short trips for which we bought it. Use-case matters!

      Every Tesla made in America contains 500 kilos of Japan's finest batteries. Honda may hate the EV but Panasonic does not.

        > Japan's finest batteries

        Aren’t all Teslas made in the US supplied with American made batteries? In partnership with Panasonic, for the Model 3, but still a Tesla factory in Nevada. And I think 4680s are all Tesla made, correct?

        • jeffbee 10 minutes ago
          No, they are all 100% made by Panasonic, with Panasonic technology, in buildings that Panasonic master-leases from Tesla. The only thing Tesla has contributed is the shell and the sign outside. Panasonic developed the 4680 form factor at Tesla's request, by the way that program has been a major failure.

    Scientists found a way to extract up to 90% of oxygen from air! They call it “breathing”.

      > Scientists found a way to extract up to 90% of oxygen from air! They call it “breathing”

      No, they don't and no, they wouldn't. "Inhaled air [at sea level] contains 21% O2 while exhaled breath contains approximately 16% O2 and 5% CO2" [1]. 24% recovery.
