But I did read further. I even clicked on one of the links.
This one: https://en.wikipedia.org/wiki/Spodumene

Note the picture of a rock. Composition LiAl(SiO3)2

That isn't double digits parts per million - that is one
atom in ten and so a really nice ore.

The dozens parts per million is the crustal average.

Lets look at a conversation of yours a bit earlier:

Wikipedia was chosen as an accessible site with no third party
links. You can even download an offline version, which is
rather nice.

Lets split that into two claims. My first claim: LiFePo solves
the cobalt problem. The reference in the first paragraph of

https://en.wikipedia.org/wiki/Lithium_iron_phosphate_battery

tells you that two years ago it already was 31% of all EV
batteries and that is cobalt free. It has only gone up since.

But if you don't like wikipedia, then just recall your
conversation with Erik in Australia right here on this
list. If you scroll back just a bit, you'll see the part
where he tells us that he owns 46kWh of them. LFP is real
and pervasive.

The my second claim: "sodium is about to replace lithium too".
That is a statement about the future, and so difficult to
settle conclusively right now. But CATL has already built
a hybrid sodium-lithium pack which can be found in
several car models. Seems like those industrious PhDs are
hard at work on the production line too.

4C charging is big news on its own too. And for Canadians:
Note the claimed temperature range. So strange that your
continent is making it hard to import them.

That is not at odds, that is orthogonal. How they are going about
insulating other parts of their supply chain from external factors
is a different topic.

My point exactly. Hence the propaganda. From the "global
north". An unfortunate term, but has illustrative value
here.

Both can be true. Actually they usually work together. Propaganda
costs money and effective propaganda makes money. Would
it be less triggering if I used the word marketing rather
than propaganda or disinformation ? Historically the
only difference was who is paying for it - the state or
the corporation, but that seems to be blurring too.
