    The running theory I had seen was that they were licensing out someone else’s tech, and then claiming it as their own.

    And now this article shows that to be more true than I had thought.

    Meanwhile, there’s a company out of Taiwan doing this, https://www.youtube.com/watch?v=xQFVIs4leig

    The guy cuts a cell in half with a pair of scissors, and as soon as the scissors are pulled away the little LED light comes back on.

        Same company, their newest cells are based on that tech, but with 7 years of advances, so 360Wh/kg. Which is about the same as most other top end Lithium-ion batteries, just solid-state rather than a liquid electrolyte.

          There is some specific reason why we don’t use it? Or they last too long so companies don’t want to sell them?

            They’re brand new at that energy density. They just haven’t made their way into many products.

            ProLogium is building a gigafactory in France.

            The newest batteries also seems to solve the charging issues, which was rather slow.

      That’s actually super cool, and more in line with what one might expect from the gradual progression of solid state energy storage.

      (Also, I’m a layperson, so my expectations should be taken as such.)

        YouTube is a platform for millions of accounts, it’s not a monolith of uniform quality.

        Two-Bit DaVinci is respected and credible.
