It's not a pretty big mistake, it is very intentionally trying to create drama as if this was somehow an unsolved problem threatening Humanity only to then conclude that EV batteries are both heavily regulated and economically valuable. It's just a fluff tech piece like most mainstream tech reporting.

Seems like valid concerns to me. Who is taking the batteries and putting them into grids? Do we reach a limit and then what if there’s no market to buy them? If the world is going to change over to EVs, that’s a big scale of a problem that needs to be thought through or bad things will happen.

  If there was nobody left to buy used batteries for storage, then there would still be plenty of recyclers looking to buy them. And the people who bought a 25% worn battery for storage would be looking for another new one at some point, at which time they will sell the old one off for recycling.

    So a time and resource intensive process for recycling giant heavy objects that can explode will be effective in every country of the planet at the scale of every car? I’m not saying it couldn’t be true, but I’m quite skeptical…

      There's already Li-Cycle and Redwood Materials. No obvious reason why they couldn't scale.

  Reuse like this can extend the useful life of the battery, but not forever. So sooner or later they will need to be recycled anyhow. Accordingly, I don’t think we need to worry about the market for used batteries drying up.

  The problem with the "used EV battery market" is that the damn EV batteries are lasting longer than anyone expected. So there are no batteries to develop an actual industry around, most are just one-offs.

    Nissan created a PowerWall-like division for the secondary market. That division made a commitment to only ever use secondary use batteries. (Unlike PowerWall which has yet to build one from secondary use batteries. They use fresh manufactured batteries.) Nissan's early Leafs have the reputation as the cars with the most degraded batteries coming back into the used car market, and some of Nissan's earliest Leafs were sold under a "battery leasing model" where the car was sold but the battery was still under lease from Nissan giving Nissan incentive to replace the battery if it dropped below certain warranty thresholds. Yet despite the "notorious degraded Leaf battery" and decades of the Leafs existence and batteries that possibly owners could call in lease terms for replacements out there, statistics show that the vast majority of Leaf batteries are still in primary usage (people are still driving those "degraded" batteries, there is a used car market for them) and Nissan claims they've yet to see enough batteries enter the secondary use market to build even a single one of their PowerWall-equivalent products.

      I wonder how many households realized they didn't need all that range after all since they have a second ICE car anyways. So the Leaf pretty much stays in a 30 miles radius of the house.

        From my own anecdotal evidence I think a lot of people absolutely underestimate the impact of home charging (even at "trickle" Level 1 in the US) versus "range anxiety". In the nearly a decade I've had my PHEV, two of my three daily commutes I could and did entirely every day on the range I can Level 1 trickle charge entirely at home overnight. People massively over-estimate the range they think they need because they don't take things like home charging into account.

    Which doesn’t sound like much of a plan once the entire worlds cars contain giant batteries.

      There isn't enough supply to support commercial versions yet. When there is, expect budget powerwalls. Used batteries would be perfect since home backup rarely sees full discharge. This is a problem the market is perfectly capable of solving. Batteries are valuable.

> create drama as if this was somehow an unsolved problem threatening Humanity The number one issue people around me have when talking about EVs isn't even range or cold these days, it's that they read somewhere batteries aren't recycled, together with some total cost back of the envelope calculation that showed an EV pollutes at least as much as a fossil fuel vehicle. Some of them are convinced hydrogen and fuel cells are the only way forward. Now, I try to formulate rebuttals based on my engineering knowledge, but I tried to do my homework and could not find reliable information. My hunch is EV is a young, rapidly scaling product class/industry/market (compared to entrenched fossil fuel engines) so the process has to scale up to be cost efficient and even work at all, it just can't happen overnight, but that no, they're not going to throw batteries in landfills. My second hunch is that those otherwise green-biased, reasonable people get strangely irate about the thing to the point of persisting with buying ICEs so I'm thinking there's some agenda carried through memetic manipulative propaganda somewhere around it.
