Wait... did they do all three?

“Global action requires working together to access critically important materials,” Meng said.

So... nope.

Huh ?

What information are you trying to convey by quoting that sentence from the article?

[–] [email protected] -1 points 4 months ago (1 children)

If materials are not easy to access, then it won't scale cheaply.

You might want to re-read the article. That quote was talking about lithium ion batteries.

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.

Lithium deposits are also concentrated. The “Lithium Triangle” of Chile, Argentina and Bolivia holds more than 75% of the world’s lithium supply, with other deposits in Australia, North Carolina and Nevada. This benefits some nations over others in the decarbonization needed to fight climate change.

“Global action requires working together to access critically important materials,” Meng said.

Thanks for pointing this out better than I would have!

I know colonizer-speak when I see it.

I know everyone wants to point out that she may be referring to the brutal colonialist exploitation that lithium ion battery technology rests upon - but the way the quote is placed and framed tells me instead that we are not being told everything about this "techno-miracle."

But the materials are more easily accessible for sodium. It's just supposed to have less capacity by volume.

Edit: that portion of the article you mentioned is talking about lithium ion

Fuck

there should be 4th bubble "easy"

[–] [email protected] 2 points 4 months ago

that's what fast is for.

[–] [email protected] 2 points 4 months ago

Probably not fast. You would have to setup tooling and manufacturing and supply chain. That takes years.
