If you buy a replacement battery for a phone, it's like $20. I can't imagine there is more than $1 of cobalt in there. Who among us wouldn't be willing to pay $5 more for cobalt for an ethical source? Of course, then you have to add up all the OTHER unethical stuff, environmental damage etc that goes into it...but if I saw 2 batteries on Amazon, and one had Canadian mined cobalt, and the other from Africa, I'd pay the extra $5.
