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 prices skyrocketing, putting the needed batteries further out of reach.”

Yes, interesting article and battery design, but the university PR folks certainly overplayed the "problems" with lithium. Not unusual.

I don't know much about electricity but surely an anode is necessary for electrons to flow? Sayeth Wikipedia, "Instead, it creates a metal anode the first time it is charged." Ok. I'm still not entirely clear on it but it makes some kinda sense.

The other thing is how is that a benefit?

Why should I be excited that "it creates its metal anode the first time it is charged"?

I mean this question in ELI5-fashion not in a disparaging one.

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?

During WWII Germany had limited access to chromium and cobalt so they developed alternative metallurgy for their engines etc. I know they nickel plated their cylinder bores. I’m sure there’s more detail available somewhere.

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.

They've been around forever, originally with zinc-air batteries. That must have failed somehow.

it's a mere correction, it's still higher than pre-covid

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…

This is why I've been interested in the Graphene Aluminum batteries from GMG for so long. They are producing graphene in bulk without having to mine it. Aluminum is already extremely abundant as well. I'm very optimistic because these solve so many battery issues at the same time, heat, rapid charge, sourcing.

Oh wow this is great technology. (Also surprised that it's driven by the UQ/rio-tinto. Hopefully GMG will learn from the failures of Tritium on the business side of things (as they are from similar stock))
