    there’s no discussion of what the energy density is compared to lithium-based battery chemistries

    Energy density is not a universal concern for low cost batteries. Not every energy storage device is for a car or phone.

      Sure, but as I already pointed out above, it’s very relevant for an article titled:

      China develops iron battery 80 times cheaper than lithium that can last 16 years

      This is a misrepresentation of the facts. While iron may be 80x cheaper than lithium, the iron battery built with this design will not be 80x cheaper than an equivalent lithium battery, because it will require substantially more material, as well as additional mechanical complexity (liquid pumping).

      You’re responding as if I’m criticizing the technology. I’m not. I’m criticizing the sensationalist writing of this article that is intentionally manipulative of the reader.
