Doesn't tell me anything about Energy Density, Volume, or Recharge Cycle.

Chromium mining is crucial for the steel production industry because chromium is a key ingredient in the production of stainless steel. We've been hunting and mining it for a LONG time now. Stainless is important to so many preexisting industries, such as new construction, automotive, aerospace, and household appliances. Consequently, there have been shortages in the availability and mining of chromium and this has d…
Can you recover chromium from stainless steel?

Research deals with theory. Not everything in research is immediately practical. Lots of engineering, tweaking, and testing goes into market-ready products. This announcement is an achievement for science, not a consumer-ready product.
There is research that deals only with theory, but empirical research deals with practice, even if not always pragmatics.
Lithium extraction is also environmentally damaging, whether from the … brine extraction that pumps massive amounts of water to the surface to dry. That’s a bit of a stretch. Pumping water to the surface of a dry lakebed far from most life and letting it evaporate is pretty low on the environmental impact scale from mining. I wonder how that compares to sodium extraction.
I thought the issue with evaporative brine projects was mainly the water use in generally water scarce areas. There are direct extraction technologies that are better. Sodium you can just let the ocean evaporate in ponds, although this destroys wetlands (see for example a bunch of these around the SF Bay, some being restored to their native state).
Can't wait for this to never go further than this single published paper.

These monthly breakthrough announcements are getting annoying. Seems that "several hundred cycles" was good enough to publish this one.
Eh, we start with 100 cycles and then someone has an idea and we go to 1000 and so on. Interesting times we live in.
can you use existing factories and manufacturing techniques or do you need to invent or build those. we've started hearing about solid state batteries about 15 years ago and we still dont have any at a big enough scale. if solid state batteries do takeoff it will probably takeoff first in electric aviation and supercars which can hide the cost due to a more expensive products and the need for higher density
One will hope this becomes commercially successful and the dirty process of creating and building lithium batteries goes away completely. Hope we become less dependent on China and other countries with shady labor practices (ie, child labor, minimal to no safety regulations).
Disclaimer: I really hope these batteries make it.

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…
I'm very optimistic because these solve so many battery issues at the same time, heat, rapid charge, sourcing.
