Is “pristine ceramic” that much harder to create than e.g. “pristine silicon”? Cilicon chips seem relatively cheap these days.

That is an excellent restatement of the core question. Can the process that makes "pristine ceramic" be scaled. (harder is a dependent variable on scaling difficulty.) I don't know how much harder it is to make ceramics pristine. I am inferring that it is the thing in the article that wasn't already part of making batteries so the 'new' bit. And after seeing many, many breakthroughs where the 'new' bit was doable in small scales at great expense in a laboratory, but impossible to do at scale in an automated process, I've watched those breakthroughs go from 'world changing' to 'laboratory curiosity.' So when Nature Materials publishes the paper on the process to repeatedly make tons of pristine ceramic material, then I will be excited for the new batteries that my devices will surely get in an upgrade.

I always thought that inventions were mainly judged by their merit (efficiency), I guess I was blind to the "scaling" (i.e. "actual industry") variable, and just assumed that there must be some way to automate and streamline almost everything, as long as the demand is there (as Elon Musk has recently been showing, with batteries/electric cars and rockets).

    Chemistry(and biology) is one such field: the chemical/biological process behaves very differently whether it's don't in small quantities of the lab or in the huge volumes required for a commercial effort. So think of that large($100mm) factory as a research process , that can often fail. Example: commercializing biotech often fails because it's not possible to control contamination and genetic evolution of the bacteria you grow in huge processes .

    I have found that many times when people are "talking past" each other it is because there is a belief in there somewhere that one holds one way and the other holds a different way. In this case you have illuminated it nicely, which (slightly edited) is this: I ... assumed that there must be some way to automate and streamline almost everything, as long as the demand is there. I have experienced many things over my life where this assumption was invalid. The most common reason I have seen that this assumption breaks down is that "demand" is expressly tied to "price." And more specifically when the price goes up, demand goes down (in the economic sense, the number of people willing to pay that price for a widget) and at some price the demand goes to zero. Thus "not possible" which is not literally true, it is only actually true. Do a search on "Battery breakthrough" (Google Scholar will give you better results but the web search works too) and pick any one where the improvement is >= 50% improvement in any axis (cost, charging, capacity, weight, what ever). This works best for articles that are 5 or more years old (you have to allow some time for them to come up with a way to do it), and then try to find that breakthrough used in any battery today. Sometimes you will find a 'why we couldn't do it' article but mostly it will just not be there. Even though batteries that were 50% better on any axis would seem to have a market right? And then read through to find the 'hard bit' in the break through and go back to Google Scholar and see if you can find papers related to that bit. You will find "the rest of the story" as it is sometimes said where some thing prevents wider adoption than laboratory curiosity. Here is a simpler technology, silicon anodes (announced in 2010) reviewed in 2018 [1], maybe hitting the market if they can go to production [2]. This is a simpler process and as it has matured its impact has gone down to 10 - 15%.

    > and just assumed that there must be some way to automate and streamline almost everything, as long as the demand is there Scaling a solution to the travelling salesman problem would solve many other problems. The demand is definitely there. But many people believe it cannot be done.

      That's a fundamentally different problem. "Scaling" it requires figuring out how to solve a different concrete problem every time. Scaling e.g. battery production requires figuring out how to solve the same real-world problem very efficiently.

        No, you could (possibly) solve TSP once by providing an algorithm that scales well just like inventing an industrial process. My point was that it looks very much like some problems are fundamentally difficult and have no scalable solutions.

But most silicon isn't pristine, that's why we have chip binning.
