Hoping this is a genuine breakthrough, but expecting the first comment to point out some important thing this battery can’t do in the real world…

It's a publication from a research group on a new approach they're working on. The more interesting question if there are any aspects of this that could make it unexpectedly easier to translate to the real world lol. The abstract ends with "This cell architecture serves as a future direction for other battery chemistries to enable low-cost, high-energy-density and fast-charging batteries" - it's important fundamental research and exploration.

At some point universities should really rethink how they do PR around research - at the least try and tamp down on headlines that read like something out of some grifter startup instead of a research lab

Great, yet another new battery revelation that will never come to market. Why is this? Why do we constantly hear of these amazing, technical advances, but yet we never see any of it come to market? - Lithium-Sulfur Batteries - Solid-State Batteries - Sodium-Ion Batteries - Aluminum-Ion Batteries - Silicon Anode Batteries - Magnesium-Ion Batteries - Lithium-Air Batteries - Zinc-Air Batteries - Flow Batteries - Graphen…

Some discoveries founder in the stage of figure out how to go from a science experiment to a process to manufacture actual batteries. Sometimes there are technical or economic issues that prevent commercialization. Most of the research on this has only started in the last 10 years or so and it does take time to work out the kinks. Even within the common Lithium-ion batteries, there have been constant improvements but…

Did you know Tesla Megapacks have declined in price by 44% over the past 14 months? Sometimes the changes become very visible.

Earlier quoted context omitted.

Not sure it is a 1:1 equivalent, but this site[0] claims global chromium production is at 41 million metric tons while lithium is 180,000 metric tons. So, the supply chain already exists. [0] https://www.statista.com/statistics/598320/mine-production-o...

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?

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…

Chromium is also being looked at for resistive thermal storage, due to the stability properties you mentioned. Doped chromia (Cr2O3) bricks act as both thermal storage elements and resistive heating elements up to 1800 C.

Because the market is made up of selfish human beings. First they don't care for long term environmental consequences. If that is not enough, then they use fossil because their enemies are using, and not using it means getting destroyed today.
