I assume you're talking about Colbalt mining? It was difficult to decipher your meaning.

Zero colbalt in a modern LFP battery which some cars are now using. Other battery chemistries do still use it, such as the device you used to type out your comment.

Colbalt is also used in the production of gasoline. And when it's used, it's used: more is required to refine more fuel. Whereas the colbalt in a battery remains useful again and again every time you recharge a battery.

So if you want to be mad about it, remember to be mad at your own usage as well.

edit: so the article claimed to have factored electricty generation. Cant believe you are the one being downvoted this hard. As someone who worked in the renewable energy research institute, each time people equal ev to 'clean' automatically I get crazy. The article especially mentioned china, who has a significant portion of electricty generated by coal. Even its by oil, it would produce more co2 for energy loss in conversion. The article has no merit with such flawed comparison
