I am very interested in this question, but those who raise it never have answers about the negative impacts of mining lithium.
For example, the amount of lithium needed for an EV is an order of magnitude less than the amount of steel needed. What is so bad about lithium mining that it's 10x worse than iron mining, pound for pound?
Nobody has ever answered my request for environmental concerns with a concrete environmental lithium mining concern, such as acidification that can sometimes happen with iron mining.
I've researched and researched, found nothing, which leaves me thinking that the worst case scenario for lithium is no worse than the worst case for iron.
Meanwhile, we have such immense documented harms from fossil fuel extraction that nobody ever questions again, or with the same intensity that's reserved for supposedly toxic lithium batteries.
The apparent benefit is massive, so any delay seems to cause massive harm to the environment.
I think we need to flip the question: where is the proof that coal/oil/iron is better for the environment than mining and recycling batteries? (BTW, it's at least 20 years now for grid batteries, with lifetime going up all the time...)
