Much of the lithium is mined in Australia or via salt brines in Chile.

It’s not worse environmentally than the other mined materials that go into a vehicle.

That doesn't make it a good thing.

Ok so let’s drill into it further.

Lithium gets mined once and then enters a circular system where batteries can be recycled after 10+ years in service.

It doesn’t exist in isolation either. While lithium is mined, its competitors (oil, coal, gas) are too with significantly higher environmental costs. They’re also not reusable.

Zinc Bromide flow batteries look like a great idea for static energy storage but if you’re worried about mining, I have bad news.

Are lithium batteries getting recycled? Because there are millions of pounds of disposable vapes that just get fuckin yote directly into a landfill. Then they crack and leak PFAS into the ground water.

Large car batteries can become second life static energy storage before being completely recycled .

This is one of those instances where capitalism helps us out - there’s money to be made in old batteries.

Single use vapes are pretty damn disgusting all around TBH.

So we should continue mining single-use hydrocarbons because disposable vapes exist?

[–] bizzle@lemmy.world 1 points 10 months ago

That's definitely not what I said lmfao I said I'm excited for better battery technology.

[–] CmdrShepard42@lemm.ee 1 points 10 months ago

But it does mean it isn't any worse as well. Plus lithium can be recycled.
