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…

EOS Energy (zinc-bromide grid-scale batteries), just christened their first automated manufacturing line and have entered mass production.

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.

Lithium has atomic number 3 and, along with Hydrogen and Helium, was present (at a much lower level) in the early universe. The Earth's crust contains about 20-70 parts per million (ppm) of lithium. It may be tedious to extract, but it is not like we will ever run out.

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.

This is a good overview on some of the environmental impacts: 'Environmental impact of direct lithium extraction from brines' (2023) in Nature Reviews Earth & Environment, PDF: https://www.nature.com/articles/s43017-022-00387-5.pdf

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

Seriously for real? Why did the price of the cars not drop accordingly? Curious.

They have ? Tesla has made aggressive price cuts in the last year or so .

Yes, partly it was to simulate demand, but they can only afford to do so because of their costs going down.

Tesla has not been spending on a lot of new models recently , but they have been spending heavily on making them cheaper and better.

Rivian, ford GM and every other non Chinese car manufacturer has been loosing money per car expect Tesla for a reason

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).

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…

Are there any alternative steel alloys that aren't used now for cost reasons that we'd see if there was a spike in chromium prices?

AFAIK there's no stainless steel without chromium. There are alternatives, like galvanizing or powdercoating.

I think if the price of chromium spiked enough, you'd just see more things move on to different materials. More aluminum, titanium, brass, bronze, etc. There are a lot of things made of stainless that don't necessarily have to be, simply because it's cheap and good enough.
