Lithium is abundant yes but it's a rare earth metal which doesn't mean it's actually rare but that the ore content is super low. Meaning practically speaking you have to move a whole lot of earth to get a little bit of lithium.

This makes a lot of extractions very difficult for ecological reasons.

Lithium is not a rare earth metal. https://en.wikipedia.org/wiki/Rare-earth_element

It behaves like one though. It is only found in low concentrations and never in pure form or easily accessible ores.

Lithium brines have concentrations of well over 50 ppm. That sounds low, but given that many other minerals are economically viable when measured in ppb, 50 ppm is not low at all.

You're basically referring to noble metals and the like. We use them because they are useful in very small quantities. That's not the case with lithium.

I look forward to 10-15 years from now when lack of scalability is proven and comment sections will say exactly what you're saying here as if everyone knew it all along.
