If you're the one making claims its on you to provide sources. If you're just saying things and putting question marks on the end people are going to treat it the same way they treat newspaper headlines, which is to say any headline ending in a question mark probably has an answer of no.
Na4MnCr(PO4)3 Chromium is 5 times more abundant than Lithium in earth crust (0.01% vs 0.002%). Better, but not that much ? "Regular" sodium-ion batteries with prussian blue has, it seems, the great advantage of not using any scarce elements. It would be nice to have a comparison between this solid state chemistry and the regular one.
The difference in their geochemistry is substantial so even if chromium isn't technically that much more abundant, it's significantly easier to mine. The Gibbs free energy of formation for chromium oxides and chromite is much more negative than for lithium-bearing minerals so Cr compounds are thermodynamically favored to precipitate out of melts and solutions, forming minerals with high concentrations that then get p…
Lithium has actually dropped in price by 80% over the last two years, so this part of the article is (currently) wrong: “ The lithium commonly used for batteries isn’t that common. It makes up about 20 parts per million of the Earth’s crust, compared to sodium, which makes up 20,000 parts per million. This scarcity, combined with the surge in demand for the lithium-ion batteries for laptops, phones and EVs, have sent…

I read this as asking questions not making claims.
It would have been entirely within the guidelines of polite discussion (and the site) to point out that scarcity isn't the only deciding factor, but the OP never made any assertions to that effect.

Another difference is that chromates are wildly toxic...
Other industrial lithium intermediates are also toxic, as is the concentrated brine it’s often extracted from. Since it’s concentration is so low, most lithium extraction is pretty nasty.

Yes, and conflate "totals" with proven reserves while failing to mention that people aren't really actively looking for more reserve as aggressively. But this is a PR piece for the University for which the standard problem is to magnify both the problems it avoid as well as the impact it produces. But at its core, an anode free battery has a lot of desirable properties which make this engineer feat notable. Perhaps t…
